Detailed Product Description

ZW32-12 outdoor AC high voltage vacuum circuit breakers for rated voltage 12kV, 50Hz three-phase AC power distribution equipment outdoors. Their rated current to 630A, rated short-circuit breaking current up to 20kA. Mainly used in power distribution grid in the breaking off of the combined power system load current, overload current and short-circuit current, and step-by-step to achieve the protection of distribution automation, power distribution network is a novel device. For substation and industrial and mining enterprises in the power distribution system for protection and control purposes, but also for frequent operation of rural power grids and place, in particular, apply to the city network, rural power grid construction and transformation needs.
