Summary

ZW20 series circuit breaker use three-phase non-segregated structure and has the features of stable and reliable breaking performance, no combustion and explosion danger, maintenance-free, light weight (two-thirds of similar products ), high cycle life (mechanical operating life is 10000 times) and so on. New designed spring operating mechanism is exposed in SF6 to effectively avoid traditional spring operation mechanism’s design defects, such as stagnation and rustiness, making a significant improvement in reliability.

Scope of Application

ZW20 series circuit breaker is mainly used to break and close load current, overload current and short-circuit current in the electric power system. It is used to protect and control the power distribution system in transformer substation, industrial and mining enterprises, and it is especially suitable for the transformation of the power network in rural and city. This circuit breaker can be used with FTU/dividing switch controller, so as to automatically detect, isolate and alarm the faults in main line’s section and branch, and monitor line operation. And it has the function of automatically recovering power supply in the fault segment. After adding measure and protection, control and communication functional module to the switch, it can satisfy the requirement of power distributing automation.
