The outdoor vacuum circuit breaker has function of overload and short circuit protection,controlling,measuring,remote control and remote monitoring.

ZW32-12 type outdoor high-voltage vacuum circuit breaker is used in three-phase power system of AC 50Hz, rated voltage 10kV to 12kV, as breaking, making load current. Also, the circuit breaker has the function of overload and short circuit protection, controlling, measuring, remote control and remote monitoring. This circuit breaker is applied in industrial and mining enterprises, power plant and substation for electric equipment's control and protection, and also it can be used on the occasion of frequent operation of rural power grids due to circuit breaker's repeatedly interrupting and fast reclosing ability.
