Circuit Breaker
Circuit breakers protect overload, short circuits, and overcurrent damage to the circuits. When a fault occurs in circuit, breakers cut off the current flow and then restart it once the issue is fixed. A circuit breaker may be reset and used again, unlike a fuse, which needs to be changed after just one use.
