| Message: | HCJ3 12KV 630A vacuum interrupter for vacuum contactor
1. Brief introduction
The interrupter adoption porcelain and ceramics makes to insulate the outer shell. Contact is WCCu metal alloy material advanced technique of adoption Including bulk small. Breaking the abiliting strong the life span is long, maintenanle is simple ,no explosion dangerous, no contaminate and the noise is low . The pack vacuum contactor can operate the ebery kind of electric appliances equipments, and fuse match f-c cabinet
