ZW32-12 outdoor high voltage AC vacuum circuit breaker
The ZW32-12 series outdoor high-voltage AC vacuum circuit breaker (hereinafter referred to as the circuit breaker) is an outdoor power distribution equipment with a rated voltage of 12kV 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 power distribution systems of substations and industrial and mining enterprises. It is an ideal switching device for rural power grids and urban power grid systems. The circuit breaker can be equipped with an isolation switch or an anti-inrush delay protector according to user needs. According to user requirements, it can be combined with corresponding intelligent controllers to form intelligent circuit breakers to realize distribution network automation. The circuit breaker can be equipped with a manual spring operating mechanism or an electric spring operating mechanism. The electric spring operating mechanism can be equipped with a wireless remote control.
