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