Generac RXSW100A3 Automatic Smart Transfer Switch Overview
The Generac RXSW100A3 is a 100-amp, single-phase automatic smart transfer switch in a NEMA 3R enclosure. It is designed for Generac Evolution generators and uses Digital Power Management technology so the generator can work more selectively instead of carrying every circuit at once. The switch monitors chosen circuits and supplies power to them when needed.
It is service entrance rated and installs between the main meter and the service panel, with a disconnecting breaker on both the load side and the line side. Four 24V HVAC loads can be managed with the hardware already built in, and Smart Management Modules, sold separately, extend control to up to eight more electrical loads.
