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