What are circuit breakers and how do they work?

Circuit breakers are electrical devices that protect circuits from dangerous current loads and short circuits. They are activated when the permissible current is exceeded and instantly cut off the power in the protected circuit. The devices use thermomagnetic or electronic mechanisms that detect current deviations and actuate in accordance with established parameters.

These circuit breakers are mainly used in industrial facilities where high currents and intense loads require durable and reliable protective devices. They are also suitable for the protection of large buildings and commercial sites where the safety and reliability of the power supply is of paramount importance.

Types of circuit breakers

Circuit breakers differ in their characteristics and application, the main types being:

Automatic Air Circuit Breakers (ACB) - Designed for heavy current loads and used in severe industrial conditions.
Oil Cooled Circuit Breakers - Suitable for extreme conditions and for the protection of high voltage circuits.
Electronic circuit breakers - High-tech solutions with the possibility of precise control and monitoring of current loads.

Selection of power circuit breaker

When choosing a circuit breaker, it is important to consider several basic parameters:

Rated current: Select a circuit breaker with a rated current corresponding to the needs of the installation, taking into account the maximum load.
Protection type: Different models offer thermomagnetic or electronic protection, the latter providing more precise control.
Breaking Capacity: Specifies the maximum current that the circuit breaker can withstand in a short circuit.
