3 Phase 3.6kV Vacuum Contactor - Medium Voltage Vacuum Contactor, rated voltage 3.6kV, rated current 800~2500A
General Description:
Hai Bang 3 Phase 3.6kV Vacuum Contactor – Type JCZ3-3.6D/D-800~2500A is suitable for AC 50~60Hz power systems, main circuit rated voltage 3.6kV, and rated current 800-3200A. The 3 Phase 3.6kV Vacuum Contactoris used to directly or remotely connect and disconnect the main circuit and frequently control AC motors, transformers and other electrical control occasions. Haibang 3 Phase 3.6kV Vacuum Contactor is widely used in petroleum, coal mine explosion-proof equipment and other occasions. The altitude of the environment where the 3.6kV 3 phase Vacuum Contactor is used does not exceed 1000 meters above sea level.
We have other types of 3 Phase 3.6kV Vacuum Contactors, whose rated current are 160A, 250A, 400A, 630A (JCZ3-3.6D/D-160~630A) and 3200A (JCZ3-3.6D/D-3200A). Please refer to the categories for more information.
