Product Detail

XD Baoji Electric Co.,Ltd is one of the leading China 40.5kv vacuum circuit breaker manufacturers and suppliers, as a professional company, our factory is able to produce quality 40.5kV VCB, 40.5kv vacuum circuit breaker products at competitive price.

Product Description
     VXB-40.5 Series Indoor vacuum circuit breaker is suitable to 40.5kV, three-phase A.C 50Hzpower system. It is used for control and protection switch of power distribution system, such as power plant, substation, industrial and mineral enterprise to receive and distribute power. Especially suitable for the place with frequent operation, it can be used with KYN61 Series switchgear.
     The structure of this vacuum circuit breaker is withdrawable truck, the spring mechanism in front of main circuit, the vacuum interrupter was casting in embedded pole. Equipped with isolated contacts and secondary air plug to connect to auxiliary circuit. The driving device was installed at the middle of the frame of VCB, to realize the operation of push in and pull out for VCB in the case of switchgear door closed. It can meet the standard requirments of IEC62271-100?IEC62271-1?GB1984?GB/T11022 etc.
     Overall dimension (W×D×H mm):1192×903×1610.
Technical Parameters
