Generac 100 Amp RTS Automatic Transfer Switch

120/240-Volt 3 Phase NEMA 3R Cabinet


The transfer switch monitors utility power and signals the generator to start when utility power is interrupted. When utility power returns, the transfer switch returns the electrical load from the generator back to the utility. This ensures your most important electrical loads are powered, within seconds, even when you’re away.


All RTS transfer switch
