VS1 Series Indoor HV Vacuum Circuit Breaker is the indoor HV switch with three-phase AC 50Hz, rated 7.2-12kV voltage. This circuit breaker fits the GB1984<AC HV breaker>, Jb3855<3.6~40.5kV indoor vacuum circuit breaker>, DI403<10-35kV indoor HV vacuum circuit breaker order technical specifications>and IEC standard, and possesses the reliable interlock merit ability. The breaker can carry on operation frequently, possesses the ability of opening or breaking many times and quick coinciding the floodgate. The breaker is designed front and back branch load structure, and can regard the cell installed fixed admittedly, but also can pretend to be the handcart use with hand car.

VS1 Series Indoor HV Vacuum Circuit Breaker architectural structure uses operation organization and front and back load extinguish arc room, the leading electricity loop feature is three-phase console model constructs. The arc room vertical installs in pope type insulation muff, the insulation muff is poured by APG’s technology, thus it especially resisted creeping discharge. This kind of design has reduced the dust greatly together on the surface of arc room, and not only can prevent the vacuum arc room from influence of outside, but also can ensure to appear high prevent type even in the environment of damp and hot and serious filth environment.
