Product Overview

Uninterrupted Power, When It Matters Most
The GT Power GTATS125 Automatic Transfer Switch is built for homes, businesses, and off-grid setups that simply can’t afford to go dark. With dual inlets and seamless switching between mains and generator power, it delivers total peace of mind—whether you're managing backup power or living off the grid.

Smart Switching, Your Way

In AUTO mode, the ATS uses a 2-Wire Auto Start to activate your generator the moment mains power fails. Its onboard microprocessor ensures fast, safe, and smooth transitions—keeping your appliances or systems protected and running.

Prefer hands-on control? Switch to MANUAL mode to take charge via the selector switch—ideal for load management and on-site adjustments.
