GCK Low-voltage withdrawable switchgear
Product description
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 In the power distribution
system with current up to 3150A, it is used for power distribution,
motor control and lighting and other power distribution equipment
for power conversion and distribution control.
