MVC series high voltage vacuum contactor-Shenzhen Hertz Electric Co., Ltd

MVC series high voltage vacuum contactor

The vacuum contactor is an electrical component that opens/closes the main contact part by electromagnetic force and performs circuit switching operations in a vacuum. Due to its superior performance, it is more and more widely used. Hz medium voltage vacuum contactors are also widely used in AC systems below 15kV where multiple opening and closing operation cycles are required. They are especially suitable for users who frequently operate, such as: squirrel cage winding induction motors, wound rotors and synchronous motors. Start at full or reduced voltage; turn off the power supply and capacitor. For heavy load applications and harsh environmental conditions in many industries such as mining, pulp and paper, petrochemical, and automotive, the Hz medium pressure vacuum contactor is especially recommended.

MVC vacuum contactors take electrical hold as the standard model, and can provide three types of fixed, FC combined and withdrawable rated voltages of 7.2kV (MVC-7) and 12kV (MVC-10).

Generally, FC combined and withdrawable vacuum contactors contain a fuse holder and a fuse, and the electrical performance of the fuse meets the IEC 60282-1 (2002) standard.
