Product Overview
Operating flawlessly as a Power Center (PC) or a Motor Control Center (MCC), the GCK Switchgear utilizes a highly specialized modular framework constructed from FA profiles or C-shaped profiles with a strict 20mm modular hole pattern. This advanced system delivers high breaking capacity, excellent thermal stability, and precise alignment of internal components. It strictly complies with global electrical standards, including IEC60439-1 and GB7251.1, ensuring seamless and highly secure integration into modern power infrastructure.
GCK Switchgear Features & Benefits
- Modular Safety Compartments: The cabinet is strictly divided into functional unit (drawer), busbar, and cable compartments, effectively isolating faults and preventing arc propagation.
- Flexible Drawer Configurations: Supports multiple drawer unit sizes (1/2 unit, 1 unit, 1.5 units, 2 units, and 3 units) providing immense flexibility to accommodate varying electrical components and dense functional requirements.
- Superior Mechanical Strength: The highly rigid frame provides exceptional resistance to severe short-circuit dynamic forces and operational stresses.
- Reliable Mechanical Interlock: Equipped with a foolproof mechanical interlocking device that ensures the drawer can only be operated when in the correct position, preventing unauthorized or accidental removal under active load.
- Optimized Thermal Management: Features strategically placed ventilation ports and intelligent internal partitioning to effectively manage temperature rise during continuous, high-load operations.
- Ergonomic & Maintenance-Friendly: Functional units are designed for smooth push-pull operation, with clear position indicators and easy-access cable terminals to drastically simplify field maintenance.
- Robust Environmental Protection: The main enclosure offers solid protection grades of IP30 and IP40, safeguarding critical internal components from foreign solid objects in demanding environments.

Reliability and Conclusion
FAQ
It is designed to operate seamlessly in ambient temperatures between -5°C and +40°C, at installation altitudes not exceeding 2000m. The relative humidity should not exceed 50% at +40°C, though higher humidity is permissible at lower temperatures (e.g., 90% at +20°C).
Depending on the application, the largest functional drawer (such as the 2-unit or 3-unit size) supports a maximum rated working current of up to 630A, making it ideal for heavy motor control circuits.
The GCK features a highly modular structure assembled from C-shaped or FA profiles with 20mm modular mounting holes. This withdrawable architecture allows for the rapid replacement of individual drawers without shutting down the entire distribution panel, drastically reducing maintenance downtime.
