GCS Low‑Voltage Draw‑out Type Switch Cabinet, Motor Control Center MCC Panel

GCS low‑voltage draw‑out switch cabinet is a modular motor‑control‑center switchgear, widely used in power distribution systems of power plants, petroleum, chemical, metallurgy, textile, high‑rise buildings and other industries.

It is especially suitable for large‑scale power‑plants and petro‑chemical projects with high automation requirements and computer‑interface access. Working at AC 50/60Hz, rated voltage 380(400)V / 660V, rated current up to 4000A, it undertakes power distribution, motor centralized control and reactive‑power compensation tasks in low‑voltage power supply networks.

This equipment strictly conforms to standards: IEC439‑1, GB7251, ZBK360001.

‑ Ambient temperature: ‑5℃ ~ 40℃, average temperature within 24h ≤ 35℃
‑ Installation altitude: ≤ 2000 m
‑ Relative humidity: ≤ 50% at 40℃; higher humidity allowed at lower temperature (condensation protection required)
‑ No severe vibration, impact, corrosive gas or conductive dust in installation environment
‑ Indoor installation only, avoid rain & snow erosion

1. High‑strength 8MF profile frame The main frame is welded by 8MF open‑type section steel. Both sides are pre‑drilled mounting holes of 20 mm, 100 mm pitch and Φ9.2 mm, flexible for internal component installation.
2. Two optional assembly forms Fully‑assembled structure; Partial‑frame & beam welding‑type structure, for customers to select according to site requirements.
3. Independent isolated compartment design All functional areas are physically separated: drawer unit compartment, bus‑bar compartment, cable compartment. Each section operates relatively independently, greatly improving operation‑safety, preventing fault‑spread risk.
4. Convenient hot‑swap maintenance Single drawer loop can be pulled‑out for inspection or replacement, without shutting‑down the whole cabinet, minimizing production downtime.
5. Flexible expandability Modular drawer‑unit design, you can add, remove or modify motor & feeder loops later without reconstructing the main cabinet.
