Air Circuit Breakers (ACB)

Air Circuit Breakers (ACB)

ACB is a power circuit breaker where the power contacts operate in air. Some versions employ an air blast to extend and clear the arc on contact opening, while others employ arc chutes with magnetic or thermal assists. It functions to protect the largest LV lines from overcurrent, short-circuits and ground fault.
