Wholesale 12KV Zw32-12F series outdoor AC high voltage intelligent vacuum circuit breaker VCB supplier
Summary
hw32-12F series outdoor AC high voltage intelligent vacuum circuit breaker(hereinafter referred to as circuit breaker) is suitable for 12kV and below, AC 50H2 city network and rural power distribution system. It has fault detection function, protection control function and communication function. It is installed in the 12kV overhead line responsibility demarcation point, which can realize automatic cutting, single-phase grounding and automatic isolation short-circuit fault. It is ideal for power distribution line transformation and distribution network automation construction. product
The circuit breaker can be operated manually, electrically operated, remotely operated and remotely operated. The circuit breaker is composed of three parts: the body, the operating mechanism and the controler. The isolation switch is installed by the user. The circuit breaker can be configured with CT protection current transformer) ZCT(Zero-sequence current transformer) and PT(Voltage Transformer) as the detector of the controller.
