## Description

Generac Automatic Transfer Switches are designed for use with single phase generators that utilize an Evolution or Nexus Controller. The 150 Amp open transition switch is available in single phase with service equipment rated configurations and works in tandem with the generator to monitor the utility power. When utility power is interrupted, the transfer switch automatically transfers power from the utility to the generator. When utility power returns, the transfer switch will return the electrical load from the generator back to utility. Through the use of digital power technology (DPM), these switches have the capability to manage up to 4 individual HVAC (24 VAC controlled) loads with no additional hardware. Generac's RXSW150A3 150-Amp 120/240v Single Phase Automatic Smart Transfer Switch with Service Disconnect is UL listed, measures 6.3-Inch by 30-Inch by 13.5-Inch, weighs 39-pounds and comes with a 5-year limited warranty. As the #1 selling home standby generator brand, Generac offers the best in class power products for all your home, business and personal needs.
