The Fenarro GCS Low Voltage Draw-out Switchgear is engineered for high-performance power distribution and motor control in demanding industrial and commercial environments. Its advanced draw-out design allows each functional unit (feeder, motor starter, capacitor bank) to be safely isolated, withdrawn, and serviced without de-energizing the entire panel, maximizing uptime. The structure is built with high-strength aluminum alloy frames and features advanced arc-fault management, ensuring personnel safety and equipment integrity under fault conditions. It seamlessly integrates Power Center (PC) and Motor Control Center (MCC) functionalities.
High Interrupt Capacity: Rated up to 100kA, suitable for large fault current networks.
Easy Maintenance: Plug-in connectors and clear compartment separation simplify testing and replacement.
Enhanced Safety: Shutters automatically close when a drawer is removed; full IP40 protection.
Thermal Management: Optimized ventilation design and optional air conditioners ensure stable operation.
Customizable: Nearly unlimited schematic possibilities to match specific process control needs.
Large Industrial Plants (Chemical, Steel, Automotive)
Power Generation & Substation Auxiliary Systems
Large Commercial Complexes and Hospitals
Water Pumping and Treatment Stations
