Product Overview

The ZW20F-12 outdoor column mounted high-voltage intelligent vacuum circuit breaker is an outdoor high-voltage switchgear with a rated voltage of 12kV and three-phase AC 50Hz. Mainly used for breaking. Close the load current, overload current, and short-circuit current of the power system. 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, filled with SF6 gas inside, and has good sealing performance, making it not affected by the external environment. It is a maintenance free product. Its spring operating mechanism adopts a direct acting chain main drive and a multi-stage release system, which has high action reliability and is a good product for column mounted circuit breakers.
