The Generac RXSW100A3 is a 100‑amp, smart automatic transfer switch engineered to provide seamless, reliable switching between utility and standby generator power for residential applications. Designed for 120/240‑volt single‑phase systems, this switch continuously monitors incoming utility power and automatically transfers the home’s electrical load to generator power the moment an outage is detected. When utility service is restored, the RXSW100A3 safely re‑engages normal power without user involvement, ensuring uninterrupted comfort and protection.
Built with a durable NEMA 3R enclosure, the RXSW100A3 is suitable for both indoor and outdoor installation, offering flexibility across a wide range of home layouts. Its Smart Switch technology enables advanced load management, allowing compatible Generac standby generators to prioritize essential circuits and optimize performance during high‑demand conditions.

Heavy‑duty contactors and robust electronic controls ensure consistent performance even in demanding environments.
