Generac RXSC100A3 100 Amp 120/240 Smart Switch (NEMA 3R CUL)

Generac 100A 120/240V 1-Phase Non-Service Entrance Smart Switch (NEMA 3R)

The Generac RXSC100A3 Smart Switch is a 100A non-service entrance automatic transfer switch engineered for single-phase standby generator systems operating at 120/240V. Housed in a weatherproof NEMA 3R steel enclosure, this switch uses a heavy-duty Generac contactor to perform smooth, automatic open-transition transfer between utility power and backup power.

Equipped with an integrated Smart A/C Module (SACM), the unit manages up to four 24 VAC HVAC loads out of the box without requiring external hardware. System managers can expand control to eight additional high-draw loads using external Smart Management Modules (SMM), enabling smaller generator sizing while maintaining full-home resilience backed by a 5-year limited warranty.
