Product description

        ZW20-12F(M) outdoor high-voltage intelligent (permanent magnet) vacuum circuit breaker is an outdoor high-voltage switchgear with rated voltage of 12kV and three-phase AC 50/60Hz. It is mainly used to break and close the load current, overload current and short circuit current of the power system.
        ZW20-12F(M) outdoor high-voltage intelligent (permanent magnet) vacuum circuit breaker is an outdoor high-voltage switchgear with rated voltage of 12kV and three-phase AC 50/60Hz. It is mainly used to break and close the load current, overload current and short circuit current of the power system. It is suitable for substation, industrial and mining enterprises and urban and rural distribution network for protection and control, especially for places with frequent operation and urban network automation distribution network. This product is matched with the controller to meet the requirements of the distribution automation system and to perform the traditional recloser function reliably and efficiently. It adopts a mature box-type sealing structure and has good sealing performance, so that it is not affected by the external environment. It is a maintenance-free product. Its spring operating mechanism or permanent magnet operating mechanism has high operational reliability and is the best for circuit breakers on the column.
