Outdoor Vacuum Circuit Breakers

Zw32-12 outdoor vacuum Circuit Breaker (hereinafter referred to as circuit breaker) is outdoor power distribution equipment with rated voltage 12kV, three-phase AC 50Hz. It is mainly used for switching off load current, overload current and short circuit current in power system. It is suitable for protection and control in substation and distribution system of industrial and mining enterprises, and the place of frequent operation of agricultural power grid.

Standards compliant of CCC,ISO9001,CE, CB,IEC60898.

Features

High reliability, high mechanical and electrical life;

No maintenance;

The circuit breaker has the characteristics of small volume, light weight, anti-condensation, maintenance-free, etc., and ADAPTS to harsh weather conditions and dirty environment;

Standard relay protection and quick automatic reclosing function.
