Steel Frame GCK Extraction Type Low Voltage Switchgear Motor Control Center Panel

The GCK Series Low Voltage Withdrawable Switchgear is a high-performance power distribution and motor control center designed for AC 50Hz/60Hz systems. Rated for operating voltages up to 660V, the GCK is the industry standard for facilities where power continuity is non-negotiable.

The "Extraction" design features modular, pull-out drawers (withdrawable units) for circuit breakers and motor starters. This allows technicians to replace or maintain functional units while the rest of the cabinet remains energized, virtually eliminating system-wide shutdowns. It is the premier choice for power plants, petrochemical refineries, metallurgical works, and high-rise intelligent buildings.

• Advanced Withdrawable (Draw-out) Design: Functional units are housed in independent, interchangeable drawers. The mechanical interlocking mechanism ensures a clear "Connected," "Test," and "Separated" status for maximum maintenance safety.

• High Breaking & Withstand Capacity: Engineered to handle high-current industrial loads with a short-circuit breaking capacity up to 50kA / 80kA, protecting your infrastructure from catastrophic electrical faults.

• Modular "Flexible" Framework: The cabinet utilizes a 20mm modular hole system (C-type profile), allowing for high-density arrangements—up to 9 units of 1-unit size drawers can be installed in a single cabinet.

• Total Compartmentalization: Features strict physical separation between the functional unit area, the busbar area, and the cable area. This localized design prevents arc-faults from spreading between sections.

• Superior Thermal Performance: Designed with specialized ventilation channels that utilize natural convection to keep high-amperage busbars and breakers within safe temperature limits.

1. Power Generation: Main and auxiliary power distribution for thermal, hydro, and nuclear power stations.

2. Petrochemical & Mining: Centralized Motor Control Centers (MCC) for pumps, fans, and conveyor systems in harsh industrial zones.

3. High-Rise Infrastructure: Reliable power hubs for data centers, airports, and hospitals where maintenance cannot interrupt service.

4. Water Treatment: Protecting and controlling large-scale water pump arrays with automated switching logic.

• Turnkey Customization: We build to your single-line diagram (SLD). Choose your preferred component brands (ABB, Schneider, Siemens, or CHINT) for a fully integrated solution.

• Safety Mechanical Interlocks: Our GCK units feature a "Triple-Lock" system that prevents the drawer from being pulled out while the switch is in the "ON" position, preventing accidental arc-flash.

• Precision Busbar Engineering: Tinned T2 copper busbars are used throughout to ensure maximum conductivity and resistance to oxidation in high-humidity environments.

• Space-Saving Vertical Layout: The high-density drawer arrangement allows for a significantly smaller footprint compared to traditional fixed-panel GGD cabinets.

Q: Can I mix different drawer sizes in one cabinet?

A: Yes. The GCK system is highly modular. You can mix 1/2-unit, 1-unit, 2-unit, and 3-unit drawers in the same vertical column to accommodate different motor starter sizes or circuit capacities.

Q: What is the benefit of GCK over the GGD (Fixed) type?

A: GCK is all about "Uptime." If a breaker fails in a GCK cabinet, you simply pull out the drawer and swap it for a spare in minutes. In a GGD cabinet, you would have to shut down the busbar and perform hours of manual rewiring.

Q: Are the drawers interchangeable?

A: Drawers of the same size and functional type are 100% interchangeable, which simplifies spare parts inventory for large facilities.
