7.2kV high voltage vacuum contactor and fuse combination device

GPVC vacuum contactor with high voltage fuse can break a wide range of short-circuit fault current. It is used in AC systems with a voltage of 3.6~12kV, a frequency of 50Hz/60Hz, and a large number of opening and closing operation cycles, especially suitable for frequent switching occasions. The ideal tool for operation. It is widely used in the protection and control of electrical equipment (such as high-voltage motors, transformers, capacitor banks, induction furnaces, etc.) in thermal power plants, metallurgy, petrochemicals, mining, ships and other fields. GPVC vacuum contactors are available in three configurations: electrical retention, mechanical self-retention and permanent magnet retention. The control electromagnet realizes the closing operation of the contactor through the operating mechanism, and the opening operation is realized by the opening spring.
