GGD Series Automatic Transfer Switch Cabinet IP30 IP40 Low Voltage Power Switchgear

The GGD Series Automatic Transfer Switch (ATS) Cabinet is a critical power management solution designed to ensure uninterrupted electrical service for mission-critical loads. Operating in AC 50Hz/60Hz systems with rated voltages up to 415V, this cabinet serves as the "brain" between two power sources—typically the Utility Grid and a Standby Generator.

Utilizing the proven GGD fixed-type framework, this cabinet houses high-performance motorized changeover switches or interlocked circuit breakers. In the event of a primary power failure, the integrated smart controller detects the loss of voltage and automatically transfers the load to the backup source within milliseconds, protecting sensitive equipment and maintaining operational continuity.

• Seamless Automatic Transition: Equipped with a programmable logic controller (PLC) or specialized ATS controller that monitors phase loss, under-voltage, and frequency fluctuations to trigger instant switching.

• Dual-Power Mechanical & Electrical Interlocking: Features a foolproof interlocking system that physically prevents both power sources from being connected simultaneously, eliminating the risk of back-feeding or short circuits.

• High Breaking Capacity: Engineered within the GGD chassis to handle significant short-circuit stresses, with a rated withstand current (Icw) up to 50kA.

• Flexible Operation Modes: Supports "Auto-Lead/Auto-Restore," "Auto-Lead/Manual-Restore," and "Manual Override" modes to give facility engineers total control during maintenance or grid testing.

• Robust GGD Frame: Constructed from 2.0mm thick cold-rolled steel with an 8MF profile, providing the structural integrity needed to house heavy motorized switches and large-gauge copper busbars.

1. Healthcare Facilities: Ensuring life-support systems and operating theaters remain powered during grid outages.

2. Data Centers & Telecom: Protecting server uptime by bridging the gap between utility power and UPS/Generator sets.

3. High-Rise Buildings: Managing emergency power for fire elevators, smoke extraction fans, and emergency lighting.

4. Continuous Manufacturing: Preventing costly production line stoppages in semiconductor or chemical processing plants.

• Turnkey Customization: We build to your specific load requirements. Choose from leading switch brands like ABB, Schneider, Socomec, or CHINT.

• Visual Status Monitoring: The front panel includes high-visibility LED indicators for "Source Available," "Source Connected," and "Fault," along with digital meters for real-time voltage and frequency tracking.

• Ease of Maintenance: The GGD fixed-panel design offers a spacious interior, making it easy for technicians to inspect cable terminations and test the motorized mechanism.

• Corrosion Protection: Every cabinet undergoes a rigorous multi-stage treatment process followed by an industrial epoxy powder coating, ensuring a service life of over 20 years.
