XD Baoji Electric Co.,Ltd is one of the leading China vs1 12kv vacuum circuit breaker manufacturers and suppliers, as a professional company, our factory is able to produce quality VS1 12kV VCB, vs1 12kv vacuum circuit breaker products at competitive price.
ZN63A(VS1)-12 Series Indoor vacuum circuit breaker is suitable to 12kV, three-phase A.C 50Hz power 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 KYN28 Series switchgear.
The structure of this vacuum circuit breaker is withdrawable truck, the spring mechanism in front of main circuit, the vacuum interrupter was installed in insulating cylinder. Equipped with isolated contacts and secondary air plug to connect to auxiliary circuit. The chassis was installed at the bottom 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.
