With true RMS measurements and an external voltage adjustment feature, this switch ensures precision and reliability for your power needs. ## 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: - A design based on 63A automatic circuit breakers; - Motorized or manual mode switching; - 2-3 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. 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. ## Features - WE DO NOT SELL THIS PRODUCT FOR USAGE IN USA AND CANADA - Suitable for 2-3 phase gasoline and diesel gensets - True RMS measurements - Provides external voltage adjustment feature - Works with any contactors and changeover switch types ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B078KK31JS | | Actuator Type | Push Button | | Best Sellers Rank | #1,918,600 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #1,435 in Outdoor Generator Transfer Switches | | Brand Name | 4PRO | | Connectivity Protocol | X-10 | | Connector Type | Crimp | | Contact Type | Normally Open | | Control Method | Touch | | Current Rating | 63 Amps | | Customer Reviews | 5.0 5.0 out of 5 stars (1) | | International Protection Rating | IP54 | | Item Dimensions | 9.76 x 4.92 x 4.45 inches | | Item Weight | 1.39 Kilograms | | Manufacturer | 4PRO | | Material Type | Plastic | | Model | ATS-63A, 120/208V | | Number of Positions | 3 | | Operating Voltage | 208 Volts | | Operation Mode | Automatic | | Switch Type | Push Button | | Unit Count | 1 Count | ## Product Details - **Actuator Type:** Push Button - **Brand:** 4PRO - **Connector Type:** Crimp - **Contact Type:** Normally Open - **Current Rating:** 63 Amps - **Item dimensions L x W x H:** 9.76 x 4.92 x 4.45 inches - **Material:** Plastic - **Operating Voltage:** 208 Volts - **Operation Mode:** Automatic - **Switch Type:** Push Button ## Images ![4PRO ATS-63A-4P Automatic Changeover Transfer Switch, 4 Pole, 63A, 120/208V, 50/60Hz, 2-3 Phase - Image 1](https://m.media-amazon.com/images/I/81Eeup6N8lL.jpg) ![4PRO ATS-63A-4P Automatic Changeover Transfer Switch, 4 Pole, 63A, 120/208V, 50/60Hz, 2-3 Phase - Image 2](https://m.media-amazon.com/images/I/91dfHfA5RwL.jpg) ![4PRO ATS-63A-4P Automatic Changeover Transfer Switch, 4 Pole, 63A, 120/208V, 50/60Hz, 2-3 Phase - Image 3](https://m.media-amazon.com/images/I/81ecgoDYqqL.jpg) ![4PRO ATS-63A-4P Automatic Changeover Transfer Switch, 4 Pole, 63A, 120/208V, 50/60Hz, 2-3 Phase - Image 4](https://m.media-amazon.com/images/I/916cpfLmWCL.jpg) ![4PRO ATS-63A-4P Automatic Changeover Transfer Switch, 4 Pole, 63A, 120/208V, 50/60Hz, 2-3 Phase - Image 5](https://m.media-amazon.com/images/I/81AKoH8HmXL.jpg) ## Frequently Bought Together - 4PRO ATS-63A-4P Automatic Changeover Transfer Switch, 4 Pole, 63A, 120/208V, 50/60Hz, 2-3 Phase - 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 - Mollom 6 Way Power Distribution Box with Bus Bars and Din Rail for Miniature Circuit Breaker MCB, Waterproof IP66.Padlock Available for Indoor and Outdoor Use --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/60924229-4pro-ats-63a-4p-automatic-changeover-transfer-switch-4-pole](https://www.desertcart.co.uk/products/60924229-4pro-ats-63a-4p-automatic-changeover-transfer-switch-4-pole) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-19*
