Introduction
ZW32-12 indoor and outdoor vacuum circuit breaker (hereinafter referred to as "circuit breakers") for the rated voltage of 12kV, three-phase AC 50Hz outdoor distribution equipment. Mainly used for breaking and closing the power system load current, overload current and short circuit current. For substation and industrial and mining enterprises in the distribution system protection and control purposes, and the frequent operation of rural power grids.
The circuit breaker has small size, light weight, anti-condensation, maintenance-free characteristics, can adapt to poor weather conditions and dirty environments.
