Generac RXSW100A3SPD 100A 1ph-120/240V Service Rated Nema 3R Automatic Transfer Switch with Integrated SPD Features:
Generac RXSW100A3SPD 100A Automatic Transfer Switch
Designed to deliver seamless and reliable power transfer for your home standby system. Fully service-rated, it meets the requirements to function as the main disconnect device, making installation simpler and code-compliant in most jurisdictions. What sets this switch apart is its integrated Surge Protection Device (SPD), providing an added layer of defense against damaging voltage spikes and transients that can harm sensitive electronics and appliances.
When utility power fails, the RXSW100A3SPD automatically transfers power from the grid to your standby generator. Once utility service is restored, it switches back smoothly and safely. Its open-transition design includes built-in safety delays to prevent nuisance switching and to protect both your generator and household circuits.
Engineered for durability, this switch is housed in a NEMA 3R-rated aluminum enclosure, making it suitable for both indoor and outdoor installation. Its powder-coated finish resists corrosion in harsh environments, ensuring years of reliable service. Built-in load management features allow it to control up to four HVAC loads, with the ability to expand further through Smart Management Modules (SMMs). This gives you the flexibility to prioritize critical circuits and maximize efficiency without oversizing your generator.
Backed by Generac’s trusted engineering, the RXSW100A3SPD combines automatic power transfer, whole-home surge protection, and intelligent load control into one compact solution—bringing unmatched protection and convenience to your backup power system.
