This automatic transfer switch monitors both generator and shore power circuits simultaneously, seamlessly connecting whichever source is available to your RV’s electrical loads. Dual 80-ampere Chint contactors provide reverse polarity and open ground protection when operating on shore power.

The mechanical interlock design prevents both contactors from engaging simultaneously, protecting your system from damage. A rugged plastic enclosure eliminates corrosion concerns and sharp edges associated with metal boxes. Built-in LED indicators signal reverse polarity or open ground faults, while a 30-second delay at power-up prevents nuisance transfers.
