The Cummins RA112S3 100 Amp Service Entrance Automatic Transfer Switch provides reliable automatic power management for residential backup systems. This heavy-duty system functions as a 2-Pole Switch for 120/240V Single Phase Cummins Generators, ensuring safe electricity delivery during utility failures.
Engineered for safety, the Cummins RA112S3 features a Break-Before-Make mechanism that completely isolates generator power from utility power. Security is reinforced through both a mechanical interlock and an electrical interlock control wiring system to prevent simultaneous connections to emergency and normal power sources.
Built to last, this unit comes with long-life high-pressure silver-alloy contacts that resist burning and pitting. The system is protected by a durable Aluminum Enclosure NEMA Type 3R Rated for quiet operation and flexible indoor or outdoor installation.
