Description

11kv 12KV 200A/400A/630A Indoor High Voltage VCB Vacuum Contactor


Product Description
MKVC vacuum contactor is a series of new-generation medium-voltage vacuum switch element series products developed by our company in combination with advanced product technology and experience at home and abroad. The size of the GPVC product is exactly the same as that of A-B-B's VC contactor, which can be installed in a min. 650mm mid-mounted switchgear.
Application
The MKVC vacuum contactor cooperates with a high-voltage fuse that can break a wide range of short-circuit fault currents. It is used in AC systems with a voltage of 3.6~12kV and a frequency of 50Hz/60Hz where a large number of opening and closing operation cycles are required, and it is especially suitable for frequent switching. The ideal appliance 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 plants, shipping and other fields. The GPVC vacuum contactor has three configurations: electrical holding, mechanical self-holding, and permanent magnet holding. 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:
MKVC vacuum contactors can provide rated voltage 3.6~7.2kV (MKVC7) and 12kV (MKVC12) two grades, and can be used with fuses:
MKVC 7 - from 6A to 315A
MKVC12 - from 6A to 160A
