7.2kV Vacuum Contactor 1250A
Hai Bang 7.2kV Vacuum Contactor is applicable on AC 50-60Hz power systems, rated voltage 7.2kV and 12kV, rated current 800A, 1000A, 1250A, 1600A, 2000A. This type of 7.2kV (12kV) high voltage vacuum contactor is used to directly or remotely connect and disconnect the main circuit , and to control electrical equipment such as non-inductive AC motors and transformers. The altitude of the environment where the 7.2kV high voltage Vacuum Contactor is used does not exceed 1000 meters above sea level.
We have another type of 7.2kV Vacuum Contactor, whose rated current is 160A, 250A, 400A, 630A. Please refer to the Categories for more information.
