This VCB is the new green generation VCB. It adopts monopole vacuum interrupter, which is safe, reliable and can stand extreme low temperature. The N₂ of high purity is filled as insulation gas between vacuum interrupter and ceramics. The spring-loaded cam linkage makes remote-control possible. This VCB has simple structure, high current breaking ability, safe operation and no risk of explosion. It is suitable in places of frequent operation for the loads close-opening and the opening of fault current.
