What is circuit breakers?

A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by overcurrent or short circuit. Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect individual household appliances up to large switchgear designed to protect high voltage circuits feeding an entire city.
