Overview
The GCS device is suitable for power distribution systems in power plants, petroleum, chemical, metallurgy, textile, high-rise building and other industries. In large power plants, petrochemical systems and other places with a high degree of automation that require computer interfaces, it serves as a low-voltage complete power distribution device for power distribution, centralized motor control, and reactive power compensation in power generation and supply systems with a three-phase AC frequency of 50(60)Hz, a rated operating voltage of 380V(400V), (660V), and a rated current of 4000A and below.
