Description

Overview:

GCK low-voltage withdrawable switchgear consists of two parts: power distribution center (PC) cabinet and motor control center (MCC). It is suitable for power users such as power plants, substations, industrial and mining enterprises as AC 50Hz, maximum working voltage to 660V, maximum working current In the power distribution system up to 3150A, it is used for power distribution, motor control, and lighting and other power distribution equipment.

This series of products have high breaking capacity, various scheme units can be combined arbitrarily, a cabinet can contain more circuits, saving It has the advantages of high protection level, safety and reliability, and convenient maintenance.
