The GCK low-voltage withdrawable switchgear is widely used in power plants, substations, industrial enterprises, and high-rise buildings for power distribution centers (PC) and motor control centers (MCC). It is designed for AC systems with a frequency of 50-60Hz, rated operational voltage of 660V or below, and rated current of 4000A or below. The switchgear is utilized for power distribution, centralized motor control, and reactive power compensation in power generation and supply systems.

The GCK low-voltage withdrawable switchgear is used in three-phase three-wire or three-phase four-wire systems, serving as substation, feeder, or motor-specific low-voltage distribution equipment. It enhances the capacity and mechanical strength while maintaining superior electrical performance compared to similar products. The switchgear features a robust structure, attractive appearance, high protection level, reliability, and ease of maintenance, making it suitable for upgrading low-voltage switchgear assemblies.
