What is an AC Circuit Breaker?

An AC circuit breaker is a safety switching device that automatically interrupts electrical current when it exceeds safe levels due to overload or short circuit. Unlike fuses, circuit breakers can be reset and reused — making them the preferred protection device in modern electrical installations.
