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.

Healthcare Facilities: Ensuring life-support systems and operating theaters remain powered during grid outages.
Data Centers & Telecom: Protecting server uptime by bridging the gap between utility power and UPS/Generator sets.
High-Rise Buildings: Managing emergency power for fire elevators, smoke extraction fans, and emergency lighting.
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.
Q: Can this ATS cabinet start my generator automatically?
A: Yes. The integrated controller includes a dry contact signal specifically for "Remote Start" to trigger your diesel generator as soon as grid failure is detected.
Q: What happens if both power sources fail?
A: The controller will remain in a "Wait" state. Once either source returns to within pre-set safety parameters (voltage/frequency), the cabinet will automatically select the priority source.
Q: Is it possible to customize the cabinet for outdoor use?
A: While GGD is typically indoor-rated, we offer an Outdoor Version with an IP55/IP65 enclosure, rain hood, and internal climate control (heaters/fans).
