    ZW32 Outdoor AC high voltage vacuum circuit breaker

    ZW32-12 outdoor AC high voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is an outdoor power distribution equipment with rated voltage of 12kV,24kV,40.5kV and three-phase AC 50Hz. It is mainly used to break and close the load current, overload current and short circuit current in the power system. It is suitable for protection and control in power distribution systems of substations and industrial and mining enterprises, and places where rural power grids are frequently operated. The circuit breaker has the characteristics of small size, light weight, anti-condensation and maintenance-free, and can adapt to harsh weather conditions and dirty environment.
