GPVC(R)-12 removable embedded vacuum contactor and its fuse combination

Product Description

GPVC vacuum contactor is a new generation of medium-voltage vacuum switch element series products developed by our company in combination with advanced product technology and experience at home and abroad. GPVC products are the exact same size as ABB's VC contactors and can be installed in a minute. 650mm center-mounted switchgear.

application

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.

Technical features:

GPVC vacuum contactors can provide two levels of rated voltage 3.6~7.2kV (GPVC7) and 12kV (GPVC12), which can be used together with fuses:

GPVC7 - from 6A to 315A

GPVC12 - from 6A to 160A
