ZW32-12 Permanent magnet outdoor vacuum circuit breaker
Release time:2015-06-06 01:35 Read:Time

 
●Overview
ZW32-12 type permanent magnet outdoor vacuum circuit breaker (hereinafter referred to as circuit breaker) for a period of 12 kv, rated voltage of the three-phase ac 50 hz outdoor distribution equipment Is mainly used for open circuit close load current overload current and short circuit current in power system for substation and industrial and mining enterprises for protection and control in power distribution system, and the site of rural power grid frequent operation

This circuit breaker has small volume light weight prevent condensation free maintenance and other characteristics, can adapt to the harsh climate conditions and pollution environment


●Performance advantages

This product USES the permanent magnetism operating mechanism type operation; Because of the permanent magnetic operating mechanism to provide permanent magnet retention, keep the switch in the closing position, the number of mechanical parts Mechanical transmission chain is short, thus greatly improving the reliability and mechanical life of the switch
