Product introduction
The Aierway GCK Low-Voltage Withdrawable Switchgear is a fully modular, metal-enclosed, and withdrawable low-voltage power distribution and control system. It is widely used for power distribution, motor control, and reactive power compensation in industrial plants, commercial buildings, power stations, and infrastructure projects, delivering high reliability, safety, and flexibility.
Key Features
1. Fully Withdrawable & Modular Design
– All functional units (circuit breakers, contactors, protection relays, etc.) are housed in standardized withdrawable modules (drawers or trucks).
– Each unit can be easily inserted, tested, isolated, or removed without de-energizing the entire system, ensuring minimal downtime during maintenance.
2. Compact & Space-Saving Structure
– Optimized cabinet layout with segregated compartments for busbars, functional units, and cables.
– Suitable for installations with limited space, such as electrical rooms, mezzanine floors, or compact substations.
3. High Electrical Performance
– Rated Operational Voltage: Up to 690V AC
– Rated Insulation Voltage: 1000V AC
– Rated Current:** Up to 4000A (horizontal busbar)
– Short-Time Withstand Current (Icw): Up to 80kA for 1s
