Outline
TZW32-24 type outdoor vacuum circuit breaker (hereinafter referred to as circuit breaker) is an outdoor distribution equipment with rated voltage of 24KV and three – phase alternating current (50Hz). It is mainly used for switching off, closing power system load current, overload current and short circuit current. It is suitable for protection and control in substation and distribution system of industrial and mining enterprises, and places where rural power grid is frequently operated.
The circuit breaker has the characteristics of small volume, light weight, anti-condensation, maintenance-free, etc. It can adapt to the bad weather conditions and pollution environment.
