A circuit breaker is a switching device that interrupts the abnormal or fault current. It is a mechanical device that disturbs the flow of high magnitude. A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by over-current/overload or short circuit. Its basic function is to interrupt current flow after protective relays detect a fault.
Circuit Breakers and Switches. Circuit Breakers and Switches have been crafted to cut down the flow of irregular power in industrial and naval applications.
