Hai Bang Single Phase Vacuum Contactor–TypeJCZ1-12D/D1600~2500 is suitable for AC 50~60Hz power systems, main circuit rated voltage 7.2kV, 12kV, rated current 1600A~2500A. This type of Single Phase Vacuum Contactor is mainly used as a grounding switch when a single-phase ground fault occurs. The largest current is 2500A. Single Phase Vacuum Contactors are used in arc suppression cabinets and electrical occasions that require single-phase control. The altitude of the environment where the Single Phase Vacuum Contactor is used does not exceed 1000 meters above sea level (Type G does not exceed 2500 meters).
