Description
Ensure uninterrupted power for what matters most—with the 100A 220V 4P Automatic Transfer Switch (ATS), your intelligent gateway between utility power and backup energy. Designed for homeowners, RV owners, small shop operators, and off-grid enthusiasts, this CE-certified switch eliminates the guesswork and risk of manual power transfers. Whether you're using a portable generator during storms, a solar+storage system for energy independence, or a standby inverter for medical equipment, this ATS keeps your essential circuits powered—automatically. How It Works: In Auto mode, the unit constantly monitors your primary (utility) power. If voltage drops below 85V, surges above 145V, or the power cuts out entirely, the switch activates and transfers your load to the backup source in approximately 2 seconds. Once stable utility power returns, it switches back—no intervention needed. Three red LED indicators clearly show which source is active, so you always know your system status at a glance. Need full control? Flip to Manual mode and use the ergonomic handle to select your power source—or place it in the center “OFF” position to isolate both inputs for safe maintenance. Built with dual-pole mechanical interlock design and rugged PA6 housing, this switch ensures safe, spark-free operation even under load. It’s rated for 220V AC, 50/60Hz, and supports continuous currents from 6A up to 100A—enough for multiple critical circuits like refrigeration, lighting, Wi-Fi, security systems, and life-support devices. Perfect for: Homes in storm-prone or rural areas RVs and campers connecting to shore power + generator Small convenience stores, clinics, or server rooms Cold storage units, aquariums, or pet incubators New home builds or panel upgrades planning for future backup Important Note: This is a bare transfer switch only—it does not include a generator, battery, or inverter. Professional installation by a licensed electrician is strongly recommended for safety and code compliance. Invest in peace of mind. Let your backup power work for you—not after you notice the lights are out.
Reliable 2-Second Auto Switching Between Power Sources: This 100A 220V dual-power ATS automatically monitors your main (utility) and backup (generator/solar) power. If the main source fails, it switches to backup within 2 seconds-keeping critical loads running. When utility power returns, it seamlessly switches back. Suitable for homes, RVs, and small businesses needing dependable backup
Dual Operation Modes - Auto and Manual with Clear LED Status: Set to Auto mode for hands-free switching (red LEDs show active source). Use Manual mode to control power selection directly via the handle-useful for maintenance, testing, or emergency override. Center position disconnects both sources for safe servicing
Built-in Over and Under Voltage Protection for Equipment Safety: Protects your appliances from power surges and brownouts: trips at less than 85V (undervoltage) or greater than 145V (overvoltage), and reconnects when voltage stabilizes (95V / 130V). Ensures only stable power reaches your sensitive devices
Compatible with Generators, Solar Inverters and Utility Grid (220V, 50/60Hz): Works with standard 220V North American power systems. Connect your home grid on one side, and a portable generator, solar inverter, or battery system on the other. Rated for 6A100A continuous load-suitable for refrigerators, sump pumps, lighting, medical devices, and more
Compact, Durable and Easy to Install: Made of high-strength, heat-resistant PA6 material. Fits standard electrical panels. Includes clear instructions for DIY or electrician installation. CE certified for safety and reliability. (Note: Battery or generator not included.)
Four-Pole Design with Mechanical Interlock Safety: Features 4-pole configuration ensuring complete isolation between power sources with dual-pole mechanical interlock design that prevents both sources from connecting simultaneously, providing spark-free and safe operation even under full load conditions
