Introduction
Product Overview
The 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. Mainly used for breaking and closing load current, overload current, and short-circuit current of power systems
Suitable for protection and control of substations, industrial and mining enterprises, as well as urban and rural distribution networks, especially suitable for frequently operated places and urban automation distribution networks. This product is paired with a controller, which can meet the requirements of distribution automation systems and reliably and effectively complete traditional recloser functions. It adopts a mature box sealing structure and has good sealing performance, making it not affected by the external environment. It is a maintenance free product. Its spring operating mechanism or permanent magnet operating mechanism has high reliability in operation, making it a good choice for pole mounted circuit breakers.
Product Features
