ZW32-12 outdoor column vacuum circuit breaker (hereinafter referred to as circuit breaker) is rated voltage of 12kV, three-phase AC 50Hz outdoor power distribution equipment. It is mainly used to close the load current and break the overload current and short circuit in the power system Current. The circuit breaker can be used as a sectional switch on the 12kV distribution trunk line, branch line and ring network line of the city grid, as well as a section switch on the 12kV distribution trunk line, branch line and ring network line.It can be used as an incoming switch for rural power grids, industrial and mining enterprises, living quarters and construction sites
