ZW32-12 outdoor on-column vacuum circuit breaker
Product Details
Product overview
ZW32 type outdoor column vacuum circuit breaker (below) for rated voltage 12KV, three-phase AC 50Hz outdoor high-voltage power distribution equipment.
It is mainly used for the load current, overload current and short-circuit current in the power system. It is suitable for protection and control in substations and distribution systems of industrial and mining enterprises, and is more suitable for urban and rural power grid construction and transformation and frequent operation places.
