The Cummins RA112N3 100 Amp Non Service Entrance Automatic Transfer Switch monitors utility power continuously to deliver automatic power management for residential applications. Operating as a 2-Pole Switch for 120/240V Single Phase Cummins Generators, this unit ensures seamless electricity transfer the moment utility power fails.

Engineered to satisfy strict safety regulations, the Cummins A064G345 features an independent Break-Before-Make mechanism that breaks the connection to utility power before the connection to generator power is established. System security is reinforced with a mechanical interlock and electrical interlock control wiring to prevent simultaneous connection of emergency and normal power sources.

Built for longevity and quiet operation, this switch features heavy-duty silver-alloy contacts that resist burning and pitting. The system is protected by a lightweight Aluminum Enclosure NEMA Type 3R Rated, making it fully certified for both indoor and outdoor installations.
