A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by current in excess of that which the equipment can safely carry (overcurrent). Its basic function is to interrupt current flow to protect equipment and to prevent fire. Unlike a fuse, which interrupts once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation.
