Description
       ZW32-12MF series outdoor boundary Vacuum Circuit Breaker is the outdoor distribution equipment of rated voltage 12kV, three-phase AC 50/60HZ. This VCB is mainly used in load current, overload current and short circuit current of power distribution lines opening and closing of electric power system. 

      The application of circuit breaker outdoor intelligent boundary vacuum circuit breaker on 12kV feeder overhead line can avoid the power failure of the fault-free line, reduce the power failure range, shorten the power outage time, and protect the safe operation of the main network. It can also has fault detection function, to protect control and communication function, which can realize automatic cut-off single phase ground fault and auto.isolation phase to phase short fault. The installation point uses the responsibility boundary point for the user incoming line of the 12kV distribution line, and can also be applied to the branch line connection that meets the requirements.
