With practical application, it is important not only to know the characteristics of the circuit breakers, but also to understand what they mean. Thanks to this approach, you can decide with most technical issues. Let's look at what is meant by those or other parameters specified on the labeling.

Used abbreviation.

Marking devices contains all the necessary information describing the main characteristics of the circuit breakers (hereinafter AB). What they designate will be talked below.

Time-current characteristic (VTX)

Using such a graphical display, you can get a visual representation, under what conditions the circuit power failure mechanism will be activated (see Fig. 2). On the graph, the time required to activate AV is displayed as a vertical scale. The horizontal scale shows the I / IN ratio.

The permissible excess of the standard current determines the type of current characteristics for releases in devices producing automatic shutdown. In accordance with the current standards (GOST P 50345-99), each specifies is assigned a certain designation (from the Latin liter). The allowable exceeding is determined by the K \u003d I / IN coefficient, for each species, the value set by the standard is provided (see Fig.3):

• "A" - maximum - triple excess;
• "B" - from 3 to 5;
• "C" - 5-10 times more regular;
• "D" - 10-20 multiple excess;
• "K" - from 8 to 14;
• "Z" - 2-4 more regular.

Note that this chart fully describes the conditions of activation of the solenoid and thermoelement (see Fig.4).

Considering all the above, it is possible to summarize that the main protective characteristic of AV is due to the current dependence.

List of typical time-current characteristics.

Deciding with the labeling, we turn to the consideration of various types of devices that meet the specific class depending on the characteristics.

Characteristic of the type "A"

Thermal protection AV of this category is activated when the current ratio of the circuit current to the nominal (I / I n) exceeds 1.3. Under such conditions, the shutdown will occur after 60 minutes. As the nominal current is further exceeded, the shutdown time is reduced. The activation of electromagnetic protection occurs at twofold exceeding the nominal, the trigger speed is 0.05 seconds.

This type is set in chains that are not subject to short-term overloads. As an example, the schemes on semiconductor elements can be brought, upon failure of which, the excess of the current is minor. In everyday life, this type is not used.

Characteristic "B"

The difference between this species from the previous one lies in the trigger current, it can exceed regular from three to five times. In this case, the solenoid mechanism is guaranteed to be activated at a fivefold load (de-energization time - 0.015 seconds.), Thermoelement - three-time (it is necessary to turn off no more than 4-5 seconds.).

Such types of devices have found applications in networks for which high starting currents are not characterized, for example, lighting chains.

Characteristic "C"

This is the most common type, its permissible overload is higher than that of two previous species. With a fivefold exceeding the standard mode, thermoelement is triggered, this is a circuit that turns off the power supply for one and a half seconds. The solenoid mechanism is activated when the overload exceeds the norm ten times.

The AB data is designed to protect the electrocups in which moderate start-up current may occur, which is characteristic of the household network for which the mixed load is characteristic. Buying a device for the house, it is recommended to stop your choice on this form.

Characteristic "D"

For AV of this type, high overload characteristics are characteristic. Namely, tenfold excess of the norm for thermoelement and twenty-fold for the solenoid.

Supports are used in circuits with large starting currents. For example, to protect the launchers of asynchronous electric motors. Figure 9 shows two instruments of this group (A and B).

Characteristic "k"

In such AV, the activation of the solenoid mechanism is possible when the current load is exceeded 8 times, and it will be guaranteed when there will be twelve multiple standard regime overload (eighteen more for constant voltage). Time to disable loads not more than 0.02 seconds. As for the thermoelement, its activation is possible when 1.05 is exceeded from the standard mode.

Scope of application - circuit with inductive load.

Characteristic "z"

This type is characterized by a small permissible excess of the standard current, the minimum border - two multiple from the standard, the maximum - four multiple. The parameters of the timing of thermoelement, the same as those with the characteristic K.

This subspecies is used to connect electronic devices.

Characteristic "MA"

A distinctive feature of this group is not used thermoelement to shut down the load. That is, the device protects only from the KZ, it is quite enough to connect electrical engine. Figure 9 shows such a device (C).

Talk of staff work

This parameter describes the maximum allowable value for the standard mode of operation, when it is exceeded, the operation of the load shutdown system will be activated. Figure 1 shows where this value is displayed (IEK products are taken as an example.

Thermal parameters

Under this term implies the conditions for the operation of the thermoelement. This data can be obtained from the corresponding time-current schedule.

Limit disconnecting ability (PKS).

This term denotes the maximum permissible load value at which the instrument can break the chain without losing performance. In Figure 5, this marking is marked with a red oval.

Categories of current program

This term is used to describe the ability of AV to disconnect the circuit before the CW current in it becomes the maximum. The devices are available with the tocoscience of three categories, depending on the time of turning off the load:

1. 10 ms. and more;
2. from 6 to 10 ms;
3. 2.5-6 ms.

Note that AV relating to the first category may not have the appropriate marking.
