Miniature circuit breakers

Miniature circuit breakers are reliable devices that protect the electrical network in which they operate. They are also referred to as overcurrent circuit breakers or colloquially as ESKA. As you know, various types of short circuits and overloads in the electrical network destroy the insulation of electrical wires. This can lead to a malfunction or even a fire. The switches work immediately, disconnecting the electrical system, so they are safe and useful.

Miniature circuit breakers: Reliable network protection devices

Miniature circuit breakers are available in several types and are labeled A, B, C and D. Circuit breakers marked with the letter A operate immediately, without delay. If there is an overload in the network, they will disconnect the electrical system immediately. Switches marked with letters B, C and D act with a slight delay. The delay time depends on the ratio of make current to rated current.

The very division of circuit breakers into types B, C and D proves their application. Group A is responsible for securing electronic devices. Group B protects devices with lower starting currents as well as resistant to thermal overloads. Group C is used for low-power installations, up to several kilowatts. Group D is used to protect devices with high power, i.e. for electric motors.

The maximum voltage at which the eska works is 440 V, and the rated current up to 125 A.

The breaking currents for circuit breakers in groups B, C and D are 25 kA. Miniature circuit breakers are appreciated for their high sensitivity and the possibility of multiple use. In our store's offer you can find switches only from reputable manufacturers. Therefore, you can be sure of their reliable operation.

In each switchgear, circuit breakers are placed in such a way that each circuit is protected by a separate circuit breaker. Often, a main switch is also installed, i.e. an isolating switch, which makes it possible to cut off the voltage in the entire installation when necessary.

Miniature Circuit Breakers: Application

Each eska allows you to quickly disconnect power in the home when there is a risk of fire. The offered miniature circuit breakers do not allow any short circuits and overloads in electrical circuits. They ensure that the lighting circuit is maximally secured. Or, you can stop it without cutting power elsewhere in your home. The available miniature circuit breakers should be selected depending on the total power of devices simultaneously operating in a particular circuit. You should also take into account the cross-section of the cables used to make the cable. Each lighting circuit has a conductor cross-section of 1.5 mm2. The switch, on the other hand, is to be its most sensitive element. This allows it to work, interrupting the flow of electricity and preventing the entire circuit from melting the wires. The miniature circuit breakers work without any problems when the conductors of the cable touch each other or when the short circuit results from accidentally entering the conductors of a metal device.

Undoubtedly, this type of circuit breaker is a great alternative to fuses that were used in households until recently. Their compact design guarantees much better protection against electric shock or fire. The principle of operation is simple: the lighting circuit is interrupted when the switch detects an increase in the value that the rated current is taking at a given moment.

Therefore, it is not surprising that this solution is becoming more and more popular - miniature circuit breakers, popular E-connectors, are more and more often found both in single-family houses and in public utility buildings. They are the basic protection of any electrical installation. Durability, resistance and excellent parameters of the miniature circuit breakers contribute to their perfect operation. Therefore, it is worth looking at the specifications of individual components and choosing the most appropriate solution for a specific electrical installation.
