GCS1 Widely used indoor urban low voltage switchboard
- Good practicability
- Flexible design
- High security
- High reliability
GCS1 fixed-separated low voltage main marine switchboard is a domestic advanced product, based on the withdrawable switchgear and self-developed according to the user's powder distribution special requirement and project practicability.
GCS1 fixed-separated low voltage main marine switchboard is widely applied to power distribution system and powder control center of power plants, petroleum, chemical, metallurgical ,textile and high-rise buildings. It is applicable to three-phase four-wire and three-phase five-wire power systems with three-phase AC 50, rated voltage 380V and rated current 6,300A and below as power acceptation and distribution. The device can be divided into power distribution center (PC Cabinet) and motor control center (MCC cabinet) by its application.
