1. 33kv 400A 630A Vacuum Circuit Breaker Control And Protection

Vacuum Circuit Breaker can not only cut off or close the no-load current and load current in high-voltage circuit, but also cut off the overload current and short-circuit current through the function of relay protection device in case of system failure. It has quite perfect arc extinguishing structure and sufficient current breaking capacity, which can be divided into oil circuit breaker (multi oil circuit breaker, high-voltage circuit breaker, high-voltage circuit breaker) Low oil circuit breaker, sulfur hexafluoride circuit breaker (SF6 circuit breaker), compressed air circuit breaker, vacuum circuit breaker, etc.
