What Is an Air Circuit Breaker?

The air circuit breaker working principle differs slightly from other kinds of circuit breakers . The basic function of any circuit breaker is to stop the restoration arcing when there is a disconnection between the contacts that resists the recovery of the system’s voltage.

That is also what the air circuit breaker will do the same thing, but it works differently. The air circuit breaker operates with its contacts in the free air. They are mainly used for low voltage interruption, and they are becoming more popular and replacing high voltage oil breakers.

An air circuit breaker switches the devices which can turn on, carry and break the current under normal circuit conditions. It also helps to break the current under certain abnormal circuit conditions. The main purpose is to distribute electric energy and protect lines and power supply equipment during overloads, short circuits and under voltage.
