Generac RTSW100G3: Specs & Datasheet
MPN: RTSW100G3The Generac RTSW100G3 is a 100 A service-entrance-rated three-phase automatic transfer switch for light commercial and larger residential standby systems. Below are the published specifications for this model number.
The RTSW100G3 continuously monitors the utility feed; on an outage it starts the paired Generac generator and moves the load automatically, with no user intervention. As a service-entrance-rated unit it can serve as the main disconnect for the standby service, simplifying new installations. The NEMA 3R enclosure supports outdoor mounting, and the 30 × 24 × 10 inch cabinet keeps the footprint compact for a 100 A three-phase switch.
