IGEYAPA 100A 4P Automatic/Manual Transfer Switch AC110V — Din-Rail ATS for Home, RV & Solar, Fast 0.05s Changeover

IGEYAPA 100A 4P AC110V Automatic/Manual Transfer Switch is a compact din-rail mounted ATS that automatically or manually swaps between two power sources in under 0.05 seconds to keep critical circuits running. This compact 4-pole transfer switch is built for homes, RVs, small data closets and solar-plus-generator systems where uninterrupted power matters. It supports AC 110V at 50/60Hz, handles up to 100 amps, and accepts two independent power inputs (mains, generator or PV inverter). The unit offers automatic changeover back to the primary source when voltage stabilizes, manual override for maintenance, and clear LED status indicators for each supply.

How does the ATS make sure power keeps flowing when the main supply fails?

The ATS constantly monitors both input supplies and, if the primary (Source A) falls outside the set voltage window, it switches to the backup (Source B) in about 0.05 seconds. When the primary source returns within normal thresholds, the device transfers back automatically to restore normal operation.

• Automatic detection of overvoltage/undervoltage with preset thresholds (85V/95V undervoltage, 145V/130V overvoltage)
• Fast changeover time: approximately 0.05 seconds
• Automatic retransfer to Source A once voltage recovers
• Four-pole design supports full isolation for single-phase plus neutral or 3-phase applications

What manual controls and indicators will I use for testing or maintenance?

The switch includes a manual mode and a rotatable red handle to lock selection to Source A or Source B. LED indicators show which source is active so you can confirm status at a glance while servicing or testing your backup power setup.

• Left-side mode selector: Auto / Manual
• Right-side red handle for choosing Source A or Source B in Manual mode
• LED status lights: red for Source A, green for Source B
• Supports manual testing without interrupting connected loads during planned maintenance

What electrical ratings and protections should I consider before installing?

This ATS is rated for AC 110V at 50/60Hz with a continuous current capacity of 100A. Voltage protection thresholds are fixed for the 110V model—choose the matching version for your system voltage. The enclosure and components are designed for DIN-rail mounting inside distribution boxes.

• Rated current: 100A (continuous)
• Voltage thresholds: undervoltage 85V (recovery 95V), overvoltage 145V (recovery 130V)
• Suitable for mains, generator and photovoltaic inputs
• Designed for PZ30 distribution box installation and indoor/outdoor generator connections

How reliable and serviceable is the IGEYAPA transfer switch?

The unit is molded from high-strength PA6 polymer for heat resistance and durability while remaining lightweight for din-rail installations. Built as a PC-level infrequent switching device, it is intended for reliable automatic changeover and straightforward manual operation. IGEYAPA backs the product with a 30-day return window and a 3-year warranty for added peace of mind.

• PA6 housing for high temperature and mechanical strength
• PC-level infrequent switching design for changeover applications
• 30-day no-reason returns plus a 3-year warranty
• Customer support for installation and troubleshooting

Who is this for? This IGEYAPA 100A 4P mini ATS is aimed at homeowners with standby generators, RV and marine system integrators, small business owners protecting critical equipment, and solar installers pairing inverters with backup gensets. Choose this unit when you need a compact, fast-acting automatic/manual transfer switch for 110V dual-power setups that fits DIN-rail distribution panels and provides clear status feedback during automatic changeover and manual tests.

FAQ

Q: Can this ATS be used with a solar inverter and generator at the same time?

A: Yes. Both inputs can accept mains, generator or a photovoltaic inverter—connect one to Source A and the other to Source B.

Q: What happens when the main supply returns after a cut-out?

A: The ATS detects voltage recovery and automatically switches back to the main supply once it stabilizes within the recovery thresholds.
