[0002] A circuit breaker is a switch device that can close, carry and break the current under normal circuit conditions and close, carry and break the current under abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, protect power lines and motors, etc., and automatically cut off the circuit when they are seriously overloaded or short-circuited or undervoltage. Its function is equivalent to the combination of a fuse switch and an overheating relay. Moreover, it is generally not necessary to change parts after breaking the fault current, and has been widely used.
