GCS-type low-voltage withdrawable switchgear (hereinafter referred to as the device) is a low-voltage withdrawable switchgear designed and developed by the joint design group of the two ministries according to the requirements of the competent authorities of the industry, the majority of electric power users and the design units, which is in line with the national conditions, has high technical performance indexes, and is able to meet the needs of the development of electric power market and can compete with the existing introduced products. The device has been widely used by power users.

The device is suitable for power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries in the power distribution system. In large-scale power plants, petrochemical systems and other high degree of automation, the requirements of computer interface, as a three-phase AC frequency of 50 (60) Hz, the rated operating voltage of 380 (400, 660) V, rated current of 400 OA and below the power generation and power supply system in the power distribution, centralized control of motors, reactive power compensation of the use of low-voltage power distribution equipment.

The design of the device complies with the following standards: IEC439-1 Low-voltage switchgear and control equipment.
