Application

ZW8 12KV, three-phase AC 50HZ, which is mainly used for making and breaking load current, over-current, short-circuit current rural network, city network and miniature power system.

ZW8-12G is formed with ZW8-12 circuit breaker and isolation knife, called combined circuit breaker, may use for breaking switch.

This Circuit breaker can be installed with surge arresters, surge arresters can be installed in the entry according to user requirements, inter-office outlet side;

This Circuit breaker can be equipped with inrush current controller, it has to eliminate inrush current and over-flow-off functions.
