Generac RTSN600K3: Specs & Datasheet
MPN: RTSN600K3The Generac RTSN600K3 is a 600 A non-service-entrance-rated three-phase automatic transfer switch for commercial and industrial standby power. Below are the published specifications for this large-frame model.
At 600 A, the RTSN600K3 sits at the large end of Generac's RTS family and is typically installed downstream of a main service disconnect — its non-service-entrance rating means no utility-side breaker is built in. The NEMA 3R steel enclosure allows indoor or outdoor placement, and at 439 lbs the unit requires proper rigging and a certified technician for installation. It is UL and CUL listed for transfer switch duty in both US and Canadian jurisdictions.
