The Generac RXSC100A3 is a 100‑amp automatic smart transfer switch designed to provide reliable, seamless switching between utility and standby generator power in residential applications. Engineered for 120/240‑volt single‑phase systems, this smart switch continuously monitors incoming utility power and instantly transfers electrical loads to generator power when an outage occurs. Once utility service is restored, the RXSC100A3 automatically re‑engages normal operation, ensuring uninterrupted comfort and protection without manual intervention.
Built with a durable NEMA 3R enclosure, the RXSC100A3 supports both indoor and outdoor installation, offering flexibility for a wide range of home layouts. Its integrated Smart Management technology allows compatible Generac generators to intelligently prioritize and manage household loads, helping maintain stable performance even during high‑demand conditions.
The RXSC100A3 is fully compatible with Generac’s air‑cooled standby generator lineup, providing dependable operation, simplified installation, and long‑term durability backed by Generac’s proven engineering. Heavy‑duty contactors and robust electronic controls ensure consistent performance and reliable switching under demanding electrical conditions.
Ideal for essential‑circuit or partial‑home backup configurations, the Generac RXSC100A3 delivers smart, automatic, and efficient power transfer—keeping homes protected and powered when it matters most.
