With a robust 63A rating and compatibility with both gasoline and diesel generators, this switch ensures precision monitoring through true RMS measurements and offers user-friendly external voltage adjustments. ## Description The ATS-63A changeover switch is designed to transfer loads automatically and manually from one power source to another in a wide variety of 1-3 phase applications. FEATURES: - 1-3 phase operation, 4 pole; - Built-in mechanical and electrical interlocking; - 3-position manual switching handle (Main-OFF-Reserve); - High reliability due to stable positions of the change-over mechanism energized during switching process only; - Internal position indication lamps and externallamp outputs; - Input protection fuses. OPERATION: Device monitors mains and generator control phase voltage. In case if there is the mains control phase voltage, the device connects the load circuits to the mains inputs. If the mains control phase voltage is lost, the device comes to a waiting mode keeping the load circuits connected to the mains inputs. In case if, there is the generator control phase voltage (while mains control phase voltage is absent), the device connects the load circuits to the generator inputs. If the generator control phase voltage is lost, the device comes to a waiting mode keeping the load circuits connected to the generator inputs. In case if the mains control phase voltage is recovered, the device connects the load circuits to the mains inputs independently on having the generator control phase voltage or not. If the Auto mode switch in the OFF position, you could switch the load circuit connection between mains and generator inputs manually. Mains inputs always have priority.

The 120VAC single phase sources are not supported. **Q: Has this device some protection inside, in order to never connect accidentally both energy sources (normal grid and reserve)?** A: Dear Luis, The switch design has a built in mechanical and electrical interlocks excluding simultaneous energy source connection. ## Frequently Bought Together - 4PRO ATS-63A-4P Automatic Changeover Transfer Switch, 4 Pole, 63A, 230/400V, 50/60Hz, 1-3 Phase - ABB TLM812RCUP 125A Outdoor Load Center β€’ PowerMark Gold Outdoor Main Lug Circuit Breaker Panel β€’ Top or Bottom Feed, 3 Wire, 22,000 AIR β€’ 125 Amp, 8-Space, 16-Circuit Outdoor Load Center - Chtaixi AC Miniature Circuit Breaker, 32 Amp 120V/240V 2 Pole DIN Rail Mount Circuit Breaker, Thermal Magnetic Trip, Solar AC Disconnect Switch MCB C32 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/69604935-4pro-ats-63a-4p-automatic-changeover-transfer-switch-4-pole](https://www.desertcart.at/products/69604935-4pro-ats-63a-4p-automatic-changeover-transfer-switch-4-pole) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-06-07*
