Overview
Vacuum contactor uses vacuum interrupter to extinguish arc to frequently connect and cut off normal working current. It is usually used for 6-40.5kV system AC motor in long distance connection and disconnection.
Product Details
Product description
Vacuum contactor is electrical unit of circuit switch operation in vacuum,and main contact part of the electromagnetic force to open / close. Hertz medium voltage vacuum contactor is widely used in the application of below 15kV AC system of demanding multiple opening and closing operation cycle, especially for frequent operation, such as: squirrel cage winding induction motor, winding rotor and the full voltage or Step-down start of synchronous motor; It is particularly recommended in heavy load and bad-condition applications such as mining, pulp and paper, petrochemicals, and autos etc.
