product description:

       ZW20-12F(M) outdoor high-voltage intelligent (permanent magnet) vacuum circuit breaker is an outdoor high-voltage switchgear with a rated voltage of 12kV and three-phase AC 50/60Hz. It is mainly used for breaking and closing 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 a rated voltage of 12kV and three-phase AC 50/60Hz. It is mainly used for breaking and closing the load current, overload current and short-circuit current of the power system. It is suitable for protection and control of substations, industrial and mining enterprises, and urban and rural distribution networks, especially for places with frequent operations and urban network automation distribution networks. This product is matched with the controller to meet the requirements of the distribution automation system and can reliably and effectively complete the traditional recloser function. It adopts a mature box-type sealing structure with good sealing performance, which makes it unaffected by the external environment and is a maintenance-free product. Its spring operating mechanism or permanent magnet operating mechanism has high action reliability and is an excellent product for pole-mounted circuit breakers.
