Circuit Breakers and Switches

Voltage class classification: low voltage circuit breaker, high voltage circuit breaker;
Structural classification of low-voltage circuit breakers: air circuit breakers, molded case circuit breakers, and miniature circuit breakers;
Classification of power supply properties: AC circuit breaker, DC circuit breaker
Classification of structure and arc extinguishing principle: air circuit breaker, oil circuit breaker, sulfur hexafluoride circuit breaker, vacuum circuit breaker.
The function of the circuit breaker is to quickly cut off the power supply when a short circuit or overcurrent fault occurs in the circuit to prevent the fault from expanding. It can also be used as a general switch to realize the distribution and control of electric energy.
