Hai Bang 3.6kV Medium Voltage Vacuum Contactor is suitable for power systems with AC 50~60Hz, main circuit rated voltage 3.6kV, rated current respectively 160A, 250A, 400A, 630A. It is used to directly or remotely connect and disconnect the main circuit and frequently control AC motors, transformers and other electrical control occasions. This type of 3.6kV medium voltage Vacuum Contactor is widely used in petroleum, coal mine explosion-proof equipment and other occasions. The altitude of the environment where the 3.6kV Vacuum Contactor is used does not exceed 1000 meters above sea level.
We have other types of 3.6kV Medium Voltage Vacuum Contactor, whose rated current are 800~2500A (JCZ3-3.6D/D-800~2500A) and 3200A (JCZ3-3.6D/D-3200A). Please refer to the categories for more information.
