Hai Bang High Voltage Single Phase Vacuum Contactors are suitable for AC 50~60Hz power systems, main circuit rated voltage 7.2kV, 12kV, rated current 160A, 250A, 400A, 630A. This type of Single Phase Vacuum Contactors is mainly used as a grounding switch when a single-phase ground fault occurs. High Voltage 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 High Voltage Vacuum Contactors are used does not exceed 1000 meters above sea level (Type G does not exceed 2500 meters).
Types:
JCZ1- D(G)/D-7.2/12-160-1.6
JCZ1- D(G)/D-7.2/12-250-2.5
JCZ1- D(G)/D-7.2/12-400-4.0
