ZW32-12 outdoor vacuum circuit breaker
I. Overview
The ZW32-12 outdoor vacuum circuit breaker (hereinafter referred to as the circuit breaker) is an outdoor power distribution equipment with a rated voltage of 12kV and a three-phase AC 50/60Hz. Mainly used for breaking and closing the load current, overload current and short circuit current in the power system. It is suitable for protection and control in power distribution systems of substations and industrial and mining enterprises, and places where rural power grids are frequently operated.
This circuit breaker has the characteristics of small size, light weight, anti-condensation, maintenance-free, etc., and can adapt to harsher climatic conditions and dirty environments.
