ASAP Semiconductor LLC
Circuit Breakers How to Protect Electrical Circuit from Damage : A circuit breaker is designed to protect an electrical circuit from damage if it ever short circuited or from overloading. This is an electrical switch that is automatically operated in the event of overload. Its core function is to interrupt the current flow when it detects a fault condition. Unlike a fuse, a circuit breaker does not have to be replaced after its operation. The circuit breaker can be reset, manually or automatically, to go back... (read more) -
