1250A Vacuum Contactor
Hai Bang low Voltage Vacuum Contactor – Type CKJ3-1.14J(D)/D-800~1250 is applicable on AC 50-60Hz power systems, rated voltage 1140V, rated current 800-1250A. This type of low voltage vacuum contactors are used to Directly or remotely connect and disconnect the rotor circuit of the winding motor. This type of 1.14kV vacuum contator is suitable for electrical control occasions requiring high current control under AC-1 or AC-2 usage category.It is widely used in phase advancers, soft-start cabinets, and high-frequency electric furnaces. The altitude of the environment where the Vacuum Contactor is used does not exceed 1000 meters above sea level.
