Our low voltage switchgears have two models, GCK and GCD. GCK Low voltage withdrawable switchgears are specially engineered for power distribution and electric motor control operations. It is suitable for 380V alternating current three phase four line and three-phase five line systems.

This product uses a combined assembly basic framework and withdrawable structure, so it can be equipped with components such as a door, baffle, separator, drawer, installation rack, bus and other electric component according to your needs. The withdrawable structure also makes maintenance convenient. Its internal structures are zinc plated or plastic spray painted to maximize corrosion resistant performance.
