What is ACB – Air Circuit Breaker?

Air Circuit Breaker (ACB) is electronic equipment that is used for the protection of electric circuits from short circuits or overcurrent. The ACB operates at atmospheric pressure in air. ACB is used in the switching mechanism and protection of the electrical system.

Working Principle of Air Circuit Breaker

When a fault occurs in a circuit, the first main contacts of ACB are separated and current of the circuit is shifted to another contact termed as arching contact. The arcing contacts get disconnected and the arc is pulled away from the contacts. With the phenomena of electromagnet effect the arc is moved upward. The arc runner allows the arc ends to travel with itself. With the movement of arc runner, arc is allowed to move upward and the connection is split in this way.
