Description

7.2kV 630A Vacuum Contactor - High Voltage Vacuum Contactor, rated voltage 7.2kV, rated current 160A, 250A, 400A, 630A

General Description:

Hai Bang 7.2kV 630A Vacuum Contactor is applicable on AC 50-60Hz power systems, rated voltage up to 7.2 kV, rated current 160A, 250A, 400A, 630A. Haibang 7.2kV 630A Vacuum Contactor is widely used in power grid reactive power compensation, chemical industry, metallurgy, water supply and drainage treatment, underground coal mine equipment and other occasions. This type of high voltage vacuum contactor is used to directly or remotely connect and disconnect the main circuit and frequently control capacitive loads, AC motors, transformers and other electrical equipment. The altitude of the environment where the 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 800A, 1000A, 1250A, 1600A, 2000A. Please refer to the categories for more information.
