Yak bachimo, characteristic "D" in living booths is unacceptable. Characteristic "C". Automation with the characteristics of the largest expansion and available for sale. You can get stuck in electrical circuits, which you can change at the same station

Sixteen amperes automatic wimicach, which can be designated as an electric machine 16 A, is brought up to the type nominal strum 16 amperes, regardless of the type of hour-stream characteristics and the number of poles of the machine. The 16A automatic machine often zastosovuetsya at the hands of the vagrant minds.
Three main parameters are passed to the article of the machine, which are important for zastosuvanna in automation, and as indicated on the butt in the image, the number of poles of the machine, then the nominal strum of the machine is indicated, and in the article the indication of the hour-strum characteristic is indicated.

Pressure 16A automatic vimikacha

Automatic machine 16A can trim three hours. full of tightness connection to the electrical wiring with a sixteen-ampere automatic device, which is protected, to become 3.5 kW at a time of single-phase life change strum with a voltage of 220 volts active ambition. Three and a half kіlovati v_dpov_daє rated strum machine equal 16 amperes, with great strums, which runs three times along the lancet, which is protected by an automatic machine, the automatic guard 16A spratsyuє and turn on the livelihood up to its own hour-strum characteristic.
When the automatic switch 16a is connected to the outage of a three-phase electric lance, the intensity of the automatic switch can reach 11.6 kW, so it can be set to 3.5 kW per one phase pole of the automatic switch trikutnik, which allows you to connect great excitement.
When connected three-phase vanishing a trick-or-treater, total exhaustion, which reaches 18.2 kW, (6 kW per pole) can be cut off by electrical devices powered by wires that are protected by a 16A machine, regardless of the very power of 16A that flows through the skin of the pole of the machine.

Zastosuvannya automatic vimicach 16A

16 Amp automatic vimikach, so we call it one of the sixteen amps, it is one of the most popular types of automatic vimikacha that you can get stuck in. The popularity of the 16A automatic machine is due to one side with a great strain, which allows you to provide electricity to a small apartment, or a house, from the other side, with a small installed strain, which allows you to easily supply electricity.

In addition, a 16A single-pole and two-pole machine can protect the line of life of other electrical devices, such as a storage boiler (do not put pressure on the flow), a cleaning machine, dishwasher and others, from the reduction of up to 3.5 kW of electrical equipment.
Okremo it is possible to choose the automatic switch 16A in three and a half-pole switch as an introductory automatic device at three-phase circuit zhivlennya living object (booth), which happens not too often, but allows you to take a great deal of pressure and connect not even harder three-phase energy supplies, for example, an electric motor, for butovih needs.
Staying in the industry knows more about single-phase and three-phase options 16A machine. With this, it is often seen that automatic tripoles with curve D are switched to power the electric motors.

Ni, dear reader, the language of today is not about the selection of a virobnik, if you want, not a good one, until the trinity, what’s on the photo, I’m unbelievable. Today, I will try to find out how it is necessary to choose the parameters of automatic machines, out of their minds. Prior to the choice of automatic switches, it is necessary to approach the maximum as quickly as possible, but the most modest workers of the electric power industry will take the head blow on themselves in most emergency situations.

Whether it’s some kind of serious virobnik (well, or the one who wants to be serious) shows on the front side of the body of the machine gun a sprinkling of unintelligent, but even more important designations. Let's look at the pictures:

Numbers 1,2,3 indicate the same type of identification on automatic machines of various pickers. What the hell are you talking about? Let's sort it out in order. As if the words and abbreviations will be unintelligible, take a look at. And be patient, dear reader, the article will be long. Father:

NUMBER 1

In the photo, the number 1 indicates the nominal strum of the machine, which is measured in amperes. The most important parameter of the automatic wimicach. On the letter levoruch in the name of the nominal strumu, we still don’t have any respect, but nothing more about her.

Now, okay, do you need an automatic vimic? Correct for the zakhist, but why the zakhist? Perhaps, by-butovy tehnіk? Ni. Pobutov technique vіn protect nі. The machine protects the wiring. This is the same wiring harness, as it is connected to the PISLYA of the machine, and not in front of it. Wiring can be wired with a cable of different cut, vidpovidno, and trivaliy strum can be vitrimuvat different. The task of the machine is to prevent a trembling strum, which exceeds the value allowed for this cable. What does it seem like PUE to the drive?

Table 1.3.4. Permissible trivalium strum for wires and cords with gum and polyvinylchloride insulation with midwires

Peretin strum-conducting lived, mm 2	Strum, A, for wires, gaskets
	openly	in one pipe
		two single dwellings	three single dwellings	chotirioh one residential	one two-wire	one three core
1,5	23	19	17	16	18	15
2,5	30	27	25	25	25	21
4	41	38	35	30	32	27
6	50	46	42	40	40	34
10	80	70	60	50	55	50
16	100	85	80	75	80	70

I edited the table, cleaned up the cuts from it, so that they don’t streak in the butt. Wash the cooling cable laid in the duct, practically the same as when laying in the pipe. Tri-core cableіz zahisnym PE-conductor here you need to look like a two-person, shards in normal mode to the good guide The strum does not leak. Therefore, we need to quote the front page of the table (visions of chervonim), in which the trival of permissible streams for a two-wire cable laid in a pipe are indicated. I started to understand everything; a cable with a peretina lived 1.5 squares is protected by a 16A automatic machine (the closest standard rating for a smaller one is 18A), 2.5 squares - 25A thin ...

Ale not here Bulo! Tse in the SRSR it is possible to buy a cable from the declared virobnik peretin, it is alive at 2.5 squares and we are 100% upgraded, which is so out of the way. At the same time, "effective managers" are ready for anything for the sake of taking away additional benefits. І more important is the greater cable production, even from the underestimation of the core. Let's say we bought a cable with a 2.5-square span, measured the diameter with a micrometer, looked at the area of ​​the stake and realized that you were deceived. Real pereriz lived vyyavivsya, for example, 2.1 square.

But still not all. Did they sell you a cable like midny? Electrotechnical copper is due to a red thread, easily bent and not springy when it is done. Now wonder what you have in your hands. Did you live to be able to zhovtuvatiy vіdtinok, to bend іz zusillyam and obviously spring? I drink you. Vyrobnik protected the bag in the chemical warehouse. It's not mid, but rather brass. And the electrical conductivity of brass is lower, lower midi.

What is work? Well, first of all, not all virobniks shamble. Yes, for example, "Ribіnsk elektrokabel" or Kolchugіnskiy "Elektrokabel", which produces honest GOST produktsіyu. It's true, you'll be more expensive. І buy її in Yaroslavl without a swoop, you need to beg. Yakshko treba - zrobimo, I have a small amount of є. If you need it cheaper - you can buy it from specialized stores, the cable there is also of good quality, you can’t buy a levee. Golovnya - do not buy the cable in the vegetable store and stores that trade in the usual supply chain, from the miners to the cars.

Ale, let's turn to those of ours. Let's say, the cable you attached, let's say, is not fair. There is nothing terrible for anyone. It would be better to reduce the face value of the machine by one shave. For example, as per Table 1.3.4 for a cable with a crossover, 2.5 squares of permissible strum 25A are alive, we will install an automatic machine with a nominal value of 16A. For a cable with 6 conductors, the table allows 40A, but we can install an automatic 32A. In short, better than a troch to play it safe. Ale on the right here is no less for reinsurance. There is one more reason for lowering the nominal value of the machine by one slot from the table value. Goodbye about her.

Briefly, it’s necessary to add a bag of a part of the article, having given the wire a cable that the rating of the automatic vimikacha with the protection of reasonable reinsurance and the sphere of congestion:

We continue Rozmov about the number 1 in the photo. Now let's talk about the letter levoruch as the designation of the nominal stream of the machine:

Tsya letter indicates the characteristics of an electromagnetic (mitt) rozchipluvach. Who does not know about the attachment of an automatic vimikacha and does not know what electromagnetic rozchipluvach(EMR), please. EmR spratsovuє at times vyniknennya struma short zukannya (TKZ). But the automatic machine is guilty of vmiti vіdіznjat koroten vіd navantazhennya. For example, through a machine with a nominal value of 16A pishov strum 25A. Tse perevantazhennya, but not strum short zamikannya. Bimetal plate thermal splitter(TR) heats up and the machine turns off. But an hour is needed for this, TR is not able to spratsovuvat mittevo. And how will the strum be not 25, but 200? The axis is already similar to a korotun. So long as TR is spratsyuє, maybe you can get started! Here, on the right, EmR enters, which turns the machine off in a negligent way.

Where to go through the boundary, for which EMR can roznitsi vantazhennya like a short zamikannya that mittevo turn on the machine? On the line between and indicate the levoruch of the designation of the nominal stream of the machine. It is called out as a characteristic of an electromagnetic rozchipluvach. Tsya letter designates the multiplicity of the strum of the EmR (Iots) according to the ratio to the nominal strum of the machine (In). Tobto, vіdnoshennia Iots/Ін. Letters qi can be different, but there are three running ones themselves:

Letter "B". Iots = 3 ... 5In

Letter "C". Iots = 5 ... 10In

Letter "D". Iots = 10 ... 20In

Let's take two butts:

First example. Through an automatic vimic with a nominal strum 16A and characteristic C (C16) pishov strum 100A. Chi spratsyuє vіdsіkannya (EmR) or the machine will need an hour to spratsyuvannya TR? We multiply the nominal stream of the machine by the multiplicity factor, which gives the characteristics “C” the highest values coefficient of multiplicity from the range of the given characteristics; so that the characteristics "C" range become 5 ... 10, in rozrahunka, the value of the coefficient equal to 10 is accepted):

16x10 = 160A

Electromagnetic (mitteviy) rozchipluvach C16 automatic spratsyuє not less than strum, lower 160A. Ale, we have a strum through a warehouse machine 100A. Mean what? That's right, EMR in which butt doesn't work, it spodіvatisya is left only on TR.

Another example. Think about it, what is in the front butt, but the EmP characteristic is no longer C, but B (automatic B16):

16x5 = 80A

The minimum strum of the EMP at times is 80A. And we have 100A. Therefore, we may have a margin of 20A and that vіdsіkannya vpevneno spratsyuє; Automatically turn on automatically.

For accuracy, I erased the following picture on the Internet:

The picture is called "Hour-strum characteristic of automatic vimikacha". Knowing that the number of times the strum through the machine is higher than its nominal value, according to it you can calculate the hour of spratsovuvannya. On the little one, a light-gray color indicates the area of ​​​​spratsovuvannya of an electromagnetic rosette, and above it - a thermal one, with a dark color. I know a sprinkling of applications:

1. Strum through the automatic machine to a higher value. From the picture, it is clear that the machine can be switched on in an hourly interval from 10 to 50 seconds.

2. Strum through the machine at a higher rate than the nominal one. The automatic machine with characteristic "B" is switched on in an hour 0.01 seconds, using EMP. And the automatic machine with characteristic "C" spratsyuє in the interval of 0.01 ... 3 seconds. Do you remember the strum multiplicity interval of 5…10In for characteristic “C”? We have an eight-fold ambition, which lies in the middle of the interval. That is the hour of spratsovuvannya stale for a particular instance of the machine. For one machine EmR spratsyuє (0.01 seconds), for the other - nі, і the machine will turn on the thermal dispenser in 3 seconds.

3. Strum through the machine for 15 times changing the nominal. Here the automatic machine with the characteristics "B" and "C" is correct, and the machine with the characteristic "D" (interval of the multiplicity of the strum is 10 ... 20In) can be correct, or maybe think for 2 seconds. I know the same, tse stale in the form of a particular instance.

4. Thirty-fold revisiting of the nominal struma. Specific korotun! At this point, all three automatics ("B", "C" and "D") "click" negainno.

But still not all the “cicavos” of the pictures. Run at the upper left corner of the two lines, how to go uphill and entrust two numbers from them - 1.13 and 1.45? Tse duzhe tsіkavі figures. The coefficients of the multiplicity of the changeover, for which the machine can be used for more than a year (1.13) and less than a year (1.45). In other words, if the pressure is less, lower than 1.13, then the machine will not work. If in the interval from 1.13 to 1.45, then it will take more than a year. And if the multiplicity of revantation is greater for 1.45, for example, 1.6, then the machine will work in an hour less than a year.

Let's turn a little back, to the choice of the nominal strum of the machine. Remember table 1.3.4? Let's worry about what will be, like blindly speeding up with the table and not thinking with your head. For a cable with cores of 2.5 kV, when laid in a strobe, the table allows a trivalium strum 25A. Turn off the lights and stupidly put automatic 25A on the line. And then let's go ahead; let's say 1.4 times. 25x1, 4 = 35A! And the hour-strum characteristic tells us that the machine needs more than a year to spratsyuvannya with such a drive. Tobto, more than a year on the cable, strum mayzhe in the second time, which exceeds the limit of admissibility! And how is the laying cable so that it is not important to cool off the cold, for example, in the corrugations or in the balls of the insulation, or else at once? About those that the cable, it is possible, because of the underestimation of the peretina lived it is not forgotten. What can you see? Ta smear mi cable! Zaymannya, svidshe for everything, do not waste time, but inevitably there will be degradation of isolation, as if to make yourself known for a sprat of fate. And if such a change is made regularly, then it is richly earlier. Axis tse i є one more reason for lowering the nominal value of the machine by one slot in the form of a table value. Greetings to you, jamshuti, automatic 25A, what to stick on the rosette lines! I repeat especially for you:

1.5 sq. mm. - 10A. Lighting lines.

2.5 sq.mm. - 16A. Lines of sockets.

4 sq. mm. - 25A. Lines flowing water heaters moderate (up to 5kW) exhaustion.

6 sq. mm. - 32A Lines of electric stoves or flowing water heaters of great pressure; introduced at the apartment with gas stoves.

10 sq. mm. - 50A. Introduction at the apartment with electric stoves.

There is one more nuance before the speech. Most significant butt sockets recognized for connection to them lived іz peretina 2.5 square. And the axis of admissible strum, indications on rosettes is 16A. This machine is guilty of a mother nominal value of more than 16A, as before, that table 1.3.4 allows for a cable with cores 2.5 squares of trivalium strum 25A. Buy fit, which can be used with an ordinary plug, which is recognized for being included in a normal socket, it cannot be more than 3.5 kW, which means that it is easy to fit into the 16A limit.

Ale, let's turn to the characteristics of the electromagnetic rozchipluvach. How is it correct to choose the very letter levoruch in the nominal stream of the machine? It is clear that it is necessary to pragnate before the EMR of the machine is instilled into the practice of executing TKZ. In other words, the TV of the nominal strum of the machine on the coefficient of multiplicity may be less than the TKZ, which can be blamed in the division of the border, which is protected. If the TKZ is better, then the automatic machine will be better. But why lay up ochіkuvany TKZ? Usyi vyd three factors:

1. The length of the line. What is the greater distance from the transformer substation to your booth, what is your distance from the booth of the ASU and what is your hanging on top, the smaller the TKZ will be.

2. Peretin conductors. Like the risers of your booth are laid aluminum wires with a reline of a total of 6 squares, and at the “Lokshina” apartment of the APPV, a reline of 2.5 squares, it is not varto for the great TKZ.

3. Stan Z'ednan. A cup of "snotty" twisting in overhead shields will also reduce the amount of TKZ.

Іsnuyut spets_alnі prilad for vimіru okіkuvannogo TKZ. The price of the stench is inhumane, more homemade stench is inaccessible to that. Ale, when choosing the characteristics of an electromagnetic rozchіpluvach, you can turn the bill by simple rules:

Characteristic "B". It is important near the old housing stock, where there was no reconstruction of the internal electric lines. So, among the strong ones dacha booths, yakі otrimuyut kharchuvannya vіd repeated lines, scho mayut great dozhina. Here it is necessary to indicate that the price of automatic machines with the characteristic “B” is three times higher, the lower one with the characteristic “C” and for the free sale is not possible, the locking position. Ale, I know the same, dear reader, as if I needed it - zrobimo.

Characteristic "C". Automation with the characteristics of the largest expansion and available for sale. You can victorious in electrical circuits, which is in your master's station.

Characteristic "D". Such automatic machines, through the great multiplicity of the strum (10 ... 20In) at the industrial level, are victorious for the defense of the lines with the great starting strums, which they blame, for example, when starting the hard electric motors. But they don’t have a place! Axis to say DERZHSTANDARD 32395-2013 "Space shields for living quarters":

"6.6.5 Automatic vimikaci ..... due to the mother of the short-circuiting strums (electromagnetic, types B, C)"

Yak bachimo, characteristic "D" in living booths unacceptable.

Well, the axis, dear reader, with the nominal strum of an automatic vimikacha and with the characteristic of an electromagnetic rozchiplyuvacha, we got it. Now let's move on to number 2 in the photo.

NUMBER 2

On the photographs, the number 2 indicates the setting of the machine (OS), what is turned off, what is switched off in amperes. Tse maximum short-circuit strum, like a building machine, turn it off, saving your practice. More specifically, I’m talking about those who have no TKZ in the old housing stock, in the rural area and in the country villages great quantities And for the sake of safety, the zakhist should be brought to automatically with the characteristic “B”, so that with more sensitive EmR, which will react to the equally small stream of a short chirp.

But the situation can be directly opposite. Like you have an apartment-Novobudova, risers at the foot of the great peretina, and the stand is laid out right at the yard, the TKZ can reach even great values, up to 2000 ... 3000A! The automatic machine, obviously, will work, but if some of the contacts are formed, there will be a tight arc between them, which will need to be extinguished negligently. Axis to the building of the machine, extinguish the arc, call out to short chimes and indicate the building, which is turned on.

Vimical building can be 3000, 4500, 6000 and 10000A. Before speech, automation of OS 3000 and 4500A in the countries of the European Union before the fence. Automation from OS 3000A European firms do not vibrate; 4500-amps vibrate, but they are less likely to be sold in the open spaces of the SND. Vlasne, there is no crime at whom; vіdklyuchayuchoyu zdatnіstyu 4500A appendage for zastosuvannya at the housing stock. Axis machine type ABB model SH201L from OS 4500A:

This series is called Compact Home by ABB, so it is recognized for stasis in the living life.

Ale, I still see the priority of zastosovuvaty automatics with the inclusion of a building 6000A. On the right, in what is the main building of the machine, there is more than one resource. And for those that the difference in the price of automatic machines with OS 4500 and 6000A is about 20 rubles, the meager savings on safety are not worth it.

Well, come on, dear reader, we got the numbers 3 on the pictures.

NUMBER 3

The number 3 on the photo indicates the class of jet exchange. What is it?

Let's see how the automatic machine works when a short buzz is made:

1. A short-wave strum indicates an increase in the magnetic flux in the coil of the electro-magnetic blower.

2. The core of the coil moves under the influx of a magnetic field and shearing (provoking) the mechanism of splitting the contact group.

3. The mechanism of opening opens and closes contacts.

4. The arc, which is vinyl between the contacts, is extinguished by an arc-extinguishing chamber.

It is clear that the skin of these several stages takes an hour. Ale, we have a korotun and a majestic strum flows through the emergency line! Otzhe, the hour of spratsovuvannya of the machine can be buti yaknomenshe; If there is less than an hour, then less will you be able to make a strum short. And it’s even better, so that the machine spratsyuvav before, like a short circuit strum reaches its maximum value.

It is possible to control electric energy with the help of special jumpers with one or more active poles. The fallow type of needs for which is often a double-pole or single-pole machine.

Single-pole vimikachi (IEK) GOST R 50345-99 is an important part of the electrical rose-and-under system, the shards help to safely turn the wires in the panel of the rose-under the shield. Basically, the stench is used to supply 120 volts of life, as well as a bipolar supply of 240 volts to the circuit. Single-pole automatics are produced in a wide range, in the store you can buy 16, 20 and 30 Amperes automatic. The largest extension is a single-pole automatic switch for 16A and 25A.

Photo - single-pole machine ABB

The scheme of a single-pole vimikach, like a bipolar one, is protected for protection electrical tethers and attached, connected to them. Differential attachment (difavtomat) turns on the advancement, if it changes allowable rate. When the electrics are turned on, it may happen at the moment of a short chime in the system, otherwise the parallel mesh is overwhelmed.

Photo - priladovy case іz single-pole automatic machines

Tse needed attachments at the dacha or at home. Perevagi single-pole ELV from independent connections:

1. Defender of electrical fittings in the form of voltage strips. Also, it is necessary to control the number of devices, connected to the local line, and in case of rewitching - attaching the flow of the stream. If Yakby did not hesitate, then the immovability of the wiring appeared;
2. Defendant carried out at the apartment for the purpose of arranging;
3. Availability - cost price is cheaper, lower two-pole electric machine.

Active contactors are also equipped with a thermal response mechanism. Їx is called a single-pole thermomagnetic machine. Similar systems can be placed in chains, as if they are rewound, they heat up and can collapse.

Technical characteristics

Obviously, in the skin model, there are parameters of tension and throughput capacity. It's worth taking a look technical characteristics automatic single-pole machine type ABB (ABB):

1. Pochatkova voltage of the mesh - 230-400 V;
2. Nominal (cob) struma strength - 16A;
3. Frequency - 50Hz;
4. Throughput building (up to vimikach with a power of 60 A) - not less than 4.5 kA;
5. Pratsezdatnіst up to 10 thousand inclusive - inclusive;
6. Guaranteed validity of the scheme - up to 10 thousand inclusive - inclusive;
7. There is one pole (stars and names are single-pole), on the front of a bipolar automaton, for which they, obviously, have two;
8. class fire safety that zahistu vіd penetration pіd corpus vagita and hard particles - 20IP;
9. The maximum size of the connection port is 25 mm2;
10. Turn-on speed - less than 0.1 seconds;
11. Strum will issue a certificate for a particular building.

In the third series of the series, the automatic modular vimikach VM40 is most often installed. Vіn vіdomy its zdatnіstyu pass up to 32 Amperes, with which the maximum number of working cycles (included - switched on) - up to 30. SH201-B6.

Photo - marking of single-pole automatic machines

Krim tsyogo, a single-pole machine is also subdivided into see:

1. A - this type is victorious for the connection of group recruitment in living quarters and apartments, vicorist in the minds of butovs;
2. B - zastosovuetsya for zahistu merezh, connected to great vanity. Most of all, special lighting, or budinka with a greater need for reduced energy. Vykoristovuyutsya in systems іz spіvіdnoshennyam 3÷5 Inom;
3. C - necessary for the connection of industrial businesses, factories, companies and other measures of recognition.

Installation of a single-pole machine

Let's look at how to connect a single-pole vimikach-machine to a din-rail:

To finish often home electricians vikoristovuyutsya automatically іz spet_alnym rozch_pluvach. Attachments with such fastenings can be removed from din-rails and others on the surface even more quickly, so it’s easy to press on the current “crocodile”.

Photo - the principle of connecting automatic ELVs

Since it is not possible to independently connect a contactor, it is recommended to turn for help to fahivtsiv. Installation of a single-pole machine will cost approximately 150-200 rubles (the price may depend on a specific electrical company).

Photo - the principle of installing automatic vimics

Remember, in front of them, how to set up or change whether there is a machine (with one or a dek_lcoma poles), it is necessary to take it from your company. Otherwise, you can be fined. It is also recommended to move forward professional electrician Use the parameters and technical characteristics of the selected contactor.

Price overview

In order to buy a single-pole machine, it is necessary not only to sort out the installation parameters for you (vanity, building capacity, turn-on speed), but also dimensions. Orientation prices for see different automatic:

Models of production of Russia and the country of SND do not succumb to the quality and practice, but to do much cheaper. You can get in touch directly at the factory or at any time from the official dealers.

You can buy automatic machines from any store of electrical tools in St. Petersburg, Moscow and other places. Before that, how to choose the model you need, check your passport and quality certificate in order to secure yourself a passport.

For a long time I wanted to write a note about the correct choice of the nominal value of the machine and a short explanation about those, the stars we have, bad electricians, go out like this on a cable of 2.5 sq. mm, which pull through itself is roughly 25A, put automatic ) ) only at 16A, and not at 25A. If I’m so vvazhav, but it’s been a long time ago and it’s not like that.

Respect 1. The value of "10A struma per square millimeter of the cut" was taken by me from one of the documents of the 1990s. Yogo can be vikoristovuvati as averaged from the tables at PUE. Just look at the information for the tables from the PUE, my rozrahunki are 1-3 amperes. Well, as for the shards of automation and cables, we choose from the reserve, then it’s better to round everything up and reshape.

I thought that there are special tables, we can’t take it more easily, that everything is mega-foldable and stingy, and then it turned out that it was more necessary to open a catalog, for example, ABB…

And in catalosis we are checked by the axis of the same cicatrix of the side. I sighed out of the PDF and turned it over for a deep look. I give small pictures with active messages under them. For help, you can send a message to this forum, or get yourself started, so that you can turn on the electrics in nіs.

First, the top page of the catalog, de descriptions themselves important parameters, Designate the hour and stream of the machine’s spratsovuvannya (explanations will be later).

In a different way, I was given corrections for temperature and the number of outbuildings, which should be instructed. Tsіkavimi, more deyakі comrades z deyakikh, ahem, the office calls the snail and seems: “You know, here we have automatic switches. Sure enough, they messed up. It is necessary to replace. It’s not mine, I didn’t try anything there, but I know that their lines are revantaged, automatic warm, and the spec only adds savory.

І correction for the number of outbuildings:

So from pochnemo razbiratis. First and foremost. AUTOMATIC PROTECTION IS NOT NAVANTAGE (in the form of a flicker or something else). AUTOMATIC PROTECTION LIVE LINE (CABLE)! It is not necessary to put yourself in the brain! The machine does not give a damn about those who are following the cable there. The next task is to turn the cable into the winding, overheating it later. Tom correct choice ratings and parameters of the cable, the machine and the sockets are to blame for the offensive sequence:

1. Marveling at the vanity, yakі we need to yearn. Skilki stench spozhivayut for exhaustion, and then the strum of such a magnitude will flow through the line of life. For pereakhunku struma tension can be victorious formula: P = U * I, de P - tension, U - measure voltage (220 volts for different apartments), and I - strum. So, for strumu it will be like this: I = P / U. In fact, the formula is only valid for resistive fittings such as superb light bulbs, heaters, and teapots. But for our taste, it is possible to more roughly vikoristovuvat її і with other outbuildings.
2. To live our ambition, we need cable line(Shmat cable). Which same? We marveled at the wild sumarny strum, which we need and choose the necessary cable to cut (as I know the normal table - clad). For a hardwired laying, you can mentally estimate that 1 sq. mm cable = 10A. For prihovanoy I "on the vіki i stock" vvazhu yak 8A/sq.mm. Divimosya pererіz i rounded yogo in the bіk of the nearest zі standard row: 1.5; 2.5; 4; 6; 10.
3. The automatic machine is selected in such a way that the wine is turned on earlier, there is a kirdik below our cable. So, marveling at such streams, the machine will turn on, and marveling at the maximum stream through our cable. If the cable is not to be rolled, it is better to take it for more reworking.

Other. Let's look respectfully at the machine. The machine is folded out of two openings. Thermal and electromagnetic. Thermal expansion valve- this is a bimetal plate, as it is played when a struma passes through it, with a strong overheating it bends, making the middle of the machine important, and the machine turns on. The head of the thermal rozchіpluvach to react properly and protect the line from the shift. Vіn spratsovuvatime the same thing, if you connect five heaters and a dozen teapots. At this point, a too great (for a new one) strum will flow through the cable, and you can burn it. The axis at this point is thermally rozchіpuvach “vičіkuє” deykiy hour (and raptom short-hour navantazhennya) and turn on the line, ryatyuchi її.

Electromagnetic rozchipluvach appointments for zahistu in the form of a short zamikannya. In this case, the strum of the line will be even greater in the case of equal interests (for dozens of times), and the line needs to be turned on mittevo. For whom there is an outstanding electromagnet: a cat with a dart and a core, which I still want to bring the mechanism of an automaton to, zmushyuyuchi yogo turn around. Pishov majestic strum - the electromagnet is drawn in, breaking the line.

And the axis gave rise to cicadas. In the description of that inertia, I spoke about those who, in certain periods, a short-time variation of a parameter beyond the limits of the norm may not be critical, and the latter is not guilty of doing this paranoidly. Tse rule is introduced to automatic devices. It turns out that if you turn on the motor, for example, the pilosos or the dacha pump, in the line you can finish the big shot of the strum, I’ll change the normal one again. Obviously, for the logic of the robot, the machine is to blame for the switch. Well, for example, the motor in the working mode is 5A, and in the starting mode - 12. What work? Put the machine on 16? Ale then trapisya scho - the motor jammed, the cable shorted - fig yogo know, turn on the chi n. And the smaller one is to protect the line well, but to spratsovuvatime in the form of a dermal sneeze.

Axis schob іz tsim not soar, sensible people guessed such a river yak " characteristic of the machine“. It's right to ring out " Hour-strum characteristic Ale, in jargon, just sound like a characteristic or a category of inclusion. It is indicated by the most unremarkable letter in front of the nominal value of the machine, call all the bad things you want :) Buvaє B, C, D and for special problems - K and Z. Axis three main:

• B: 3-5 par
• C: 5-10 ratings
• D: 10-20 ratings

Characteristic B is the most sensitive and is shown before zastosuvannya in apartments and living quarters, de-energization is more active, and if the power is turned on rarely. Characteristic C - the widest (to that tezh kotit, hehe, pіd zhitlovі budіvlі), and be suitable for wild vipadkіv. And the characteristic D is sharpened for the liveliness of any evil versatility, great motors and other outbuildings, where there can be great excitement when they are turned on.

So the axis shows that for our native machine in C16 the range of strums, with which vein turns off (~ 0.1 seconds) will be 80-160 A. The axis is so! Do you hang yoga on a qualiy cable? Well, the cable is not a fool, and short-term attention can be seen.

Ale let's get busy thermal opening. As we remember, vin appointments for the defense of the line of trivial ambition. Tobto, the machine is not guilty of switching off at once, yoga hour NOT included you can become like ONE YEAR, And then more. Let's check out the catalog, but I'll tell you for C16. Before speech, for all parameters B, C, D the parameters are the same, so I will give a list for larger ratings of automatics.

Hour of swearing BILSH YEAR:

• 6A: 6.78A
• 10A: 11.3A
• 16A: 18.08A
• 25A: 28.25A

And now it's turn-off time LESS THAN A YEAR(ale does not mean that it is not the same time):

• 6A: 8.7A
• 10A: 14.5A
• 16A: 23.2A
• 25A: 36.25A

So the axis turned on by the protyazh of the year means in the highest variant those that the machine is heated for a whole year, trim the strum 23A (for a nominal value of 16A) and only then turn on. The rhodium is hateful (zadovbavsya yogo on the bachiti sockets!) denomination at 25A, especially to tell a story about the fact that before connecting your cable to 2.5 sq. mm, fuck the hell out. Axis about tse zahіd all zazvichay zabuvayut, itself vono i vyznaє nebhіdny retin cable. The cable is to blame for the trimati of the strum for the long run.

Let's get excited for the sake of interest. We take an automatic machine for 16A and a cable of 2.5 sq. mm. For this cable, for example, the maximum strum will be 2.5 * 10 = 25A. When tsimu vin dosit suttєvo heat up. A trivalium strum for laying at the wall will be 2.5 * 8 = 20A. As a result, the cable is badly cold, lie behind some clapboard in wooden booth. Vvazhaemo, so bimoviti, the biggest vpadok. Once again we wondered at the automatic machine: more than a year old automatic at 16A trim 18A, and less than a year old - 23A. The best option is more than a year old, 18A. The weakest strum on the cable is 20A. 20>18, again, you can twist the cable. Well, for a simpler explanation for customers at the tank, sound like this: “Do you have 16A written on the rosette? Otozh automatic tezh treba for 16A. And that's right! And what about our native denomination 25A, which everyone so loves to put in that fall, like 16A deceived and wines (such a bastard!) beats? And there the strum is not switched on over the year - 28A. Tse means that as long as the machine is allowed to turn on, your cable will be a good one.

Let's try to confuse a friend with a crap, about those that the machine is guilty of no more than 10A on a cable of 1.5 sq. mm. 1.5 sq. mm tse 15A or 12. For a 10A strum machine, 11 or 14A. You don’t need to marvel at it - we’ll move on. And as for lying, that at once it’s either, or else the cables with a greatly underestimated peretina, then I’m going to step on the step:

• For a cable of 1.5 sq. mm, the automatic machine is not more than 10A
• For a cable of 2.5 sq. mm, the automatic machine is not more than 16A

You can try out other cables. I looked far away for growing. So for 4 sq. mm you need 25A, and for 6 - 32. In practice, it’s so that through the inertia of the thermal dispenser of the machine, with an increase in the line of interest in C16 on all 16A, it will be possible for 5 minutes to reach the kettle of boiling join .

Now I understand why I have a lot of hair in all parts of my body, if I'm getting some sort of shield with the signature "Rosette of the fireplace" and the denomination in C25? Well, if you have another summer of sintering, then it appears that at 50 degrees of sintering, an automatic machine in 16A will turn into 14.1 A. The axis is such a cicava arithmetic!

Disrespectful, stupid and impudent salesmen and managers I zhorstko stebatim, as if the stench did not look into, but rather rush to call.
