ZW32-12FG/630 high pressure intelligent vacuum circuit breaker function and parameters
ZW32-12FG/630-20 outdoor pole permanent magnet vacuum circuit breaker, Z-represents a vacuum circuit breaker, W- stands for outdoor installation, 32-representative design serial number, 12-represents rated voltage 12KV. ZW32G-12 is a three-phase AC 50Hz outdoor high-voltage power distribution equipment. It is 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 distribution systems of substations and industrial and mining enterprises, and is more suitable for places where urban and rural power grids are built and frequently operated. zw32-12FG/630-20 General 1.2 The supplier shall implement the current national standards and power industry standards.
