[0002] A circuit breaker is a common switching device. A circuit breaker refers to a switching device that can close, carry, and interrupt the current under normal circuit conditions, and can also close, carry, and interrupt the current under abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, protect power supply lines and motors, etc. When they encounter serious overload, short circuit, undervoltage and other faults, they can automatically cut off the circuit. Its function is equivalent to the combination of a fuse switch and an over / under heat relay, etc. And generally no components need to be changed after interrupting the fault current.
