Circuit Breaker

The circuit breaker is generally composed of contact system, arc extinguishing system, operating mechanism, trip unit, and housing.

Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, etc. It can automatically cut off the circuit when serious overload, short circuit, and undervoltage faults happen. Its function is equivalent to a combination of a fuse switch and overheating and underheating relays, etc. Moreover, generally there is no need to change parts after breaking the fault current.

In the generation, transmission, and use of electricity, power distribution is an extremely important link. The power distribution system includes transformers and various high- and low-voltage electrical equipment. Among them, low-voltage circuit breakers are widely used as electrical appliances.
