Prepared for power outages? This automatic transfer switch switches your power from mains to generator in milliseconds — so you never lose electricity. Rated at 100A, 220V, it’s built from flame-retardant PC plastic, so it’s safe, durable, and resists heat and aging. You can set it to auto or manual mode, and it mounts easily on a standard 35mm DIN rail. Perfect for homes, workshops, farms, or small businesses. When the grid fails, your generator kicks in almost instantly. It handles up to 50 kA short-circuit current and works in temps from -5°C to 40°C. Comes with protective covers and a manual. Just make sure a qualified electrician installs it. Stay powered, no matter what!
