The unit monitors 3-phase normal and reserve source voltages, sends remote start command to the generating set and performs changeover switching between those 2 sources connecting the load circuits to a power source having voltages within preset limits. Device has a manual load switch lever, a manual/auto mode switch and a mechanical locking. Inputs and outputs: fire linkage control, generator remote start, external indicators. The front panel leds provide information about mains and generator power availability as well as a current switch positions. External display shows phase voltages (phase-phase), current workign mode and etc. It can be placed in a distance of 1-3 meters from the device via standard Ethernet cable. Power source voltage limits, transfer-, start- and stop delays and transfer modes are front panel configurable. Note: The delays apply only in case if the device is connected to 24VDC auxiliary power supply. Features  compatible with 120/208VAC 3 phase and 120/240 2 phase 50/60 Hz applications;  displays phase-phase voltages and current state on external LCD Display;  3 working positions: main power ON - backup power OFF; main power OFF - backup power ON; main and backup power OFF;  double complex contacts/ horizontal pulling mechanism/micro motor energy pre-storage and microcomputer control technology;  reliable mechanical interlock and electric interlock;  "Zero Position" technology. Device can be set to Zero Position under emergency situations with two way power supply cut off meeting the fire linkage requirements; ## Features - Works with any contactors and changeover switch types - Suitable for 1-3 phase gasoline and diesel gensets - True RMS measurements - Provides external voltage adjustment feature ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DL7P44Y | | Actuator Type | Push Button | | Brand | 4PRO | | Circuit Type | 2-way | | Connectivity Protocol | Ethernet | | Connector Type | Auxiliary | | Control Method | Remote | | Current Rating | 100 Amps | | Date First Available | June 15, 2018 | | International Protection Rating | IP54 | | Is Discontinued By Manufacturer | No | | Item Weight | 9.02 pounds | | Item dimensions L x W x H | 12.99 x 4.53 x 7.17 inches | | Manufacturer | 4PRO | | Number of Positions | 3 | | Operating Voltage | 208 Volts | | Operation Mode | Automatic | | Product Dimensions | 12.99 x 4.53 x 7.17 inches | | Unit Count | 1 Count | ## Product Details - **Actuator Type:** Push Button - **Brand:** 4PRO - **Circuit Type:** 2-way - **Connector Type:** Auxiliary - **Current Rating:** 100 Amps - **Item dimensions L x W x H:** 12.99 x 4.53 x 7.17 inches - **Material:** Copper - **Mounting Type:** Panel Mount - **Operating Voltage:** 208 Volts - **Operation Mode:** Automatic ## Images ![4PRO ATS-100A-4P-i Automatic Transfer Changeover Switch, 4 Pole, 100A, 120/208V, 50/60Hz, 2-3 Phase - Image 1](https://m.media-amazon.com/images/I/91NmijpqQ0L.jpg) ![4PRO ATS-100A-4P-i Automatic Transfer Changeover Switch, 4 Pole, 100A, 120/208V, 50/60Hz, 2-3 Phase - Image 2](https://m.media-amazon.com/images/I/81rwK1lB9rL.jpg) ![4PRO ATS-100A-4P-i Automatic Transfer Changeover Switch, 4 Pole, 100A, 120/208V, 50/60Hz, 2-3 Phase - Image 3](https://m.media-amazon.com/images/I/813lhsogH4L.jpg) ![4PRO ATS-100A-4P-i Automatic Transfer Changeover Switch, 4 Pole, 100A, 120/208V, 50/60Hz, 2-3 Phase - Image 4](https://m.media-amazon.com/images/I/81S6a2vHUQL.jpg) ![4PRO ATS-100A-4P-i Automatic Transfer Changeover Switch, 4 Pole, 100A, 120/208V, 50/60Hz, 2-3 Phase - Image 5](https://m.media-amazon.com/images/I/815tb46yWUL.jpg) ## Questions & Answers **Q: Hello, will this work with a Honda EU6500is generator without buying additional components?** A: This ATS switch is compatible with any type of generators having a remote start input. In case, if your generator controller does not have the remote start input, you can install one of non-expensive controllers having such input there. For example, it could be this model: SMARTGEN MGC100 Manual/Remote Start Generator Controller Module https://www.amazon.com/SMARTGEN-MGC100-Manual-Generator-Controller/dp/B06WWQVHPY/ --- ## 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.ae/products/69604938-4pro-ats-100a-4p-i-automatic-transfer-changeover-switch-4](https://www.desertcart.ae/products/69604938-4pro-ats-100a-4p-i-automatic-transfer-changeover-switch-4) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-04-23*
