Overview
The ZW32-12 series outdoor AC high-voltage vacuum circuit breakers (hereinafter referred to as circuit breakers) are outdoor distribution equipment with a rated voltage of12kV and three-phase AC 50Hz. Mainly used for breaking and closing load current, overload current, and short circuit current in electronic systems. Suitable for protection andcontrol in substations and distribution systems of industrial and mining enterprises, as well as in places with frequent operation of rural power grids. It can also serve as asegmented switch for the power grid, and after installing a controller, it can achieve automation of the distribution network.
