Description
Generac Automatic Transfer Switches are designed for use with single phase generators that utilize an Evolution™ or Nexus™ 
Controller. The 100, 200, and 400 amp open transition switches are available in single phase in both service equipment rated and 
non-service equipment rated configurations. The 150 and 300 amp open transition switches are only available in a service rated 
equipment configuration.
Standard Features
Service rated (RXSW) Generac Automatic Transfer Switches are housed in an aluminum NEMA/UL Type 3R enclosure*, with 
electrostatically applied and baked powder paint. The Heavy Duty Generac Contactor is a UL recognized device, designed for 
years of service. The controller at the generator handles all the timing, sensing, exercising functions, and transfer commands. All 
switches are covered by a 5 year limited warranty.
* Non-service rated (RXSC) switches are housed in a steel enclosure.
DPM Technology
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. When used in tandem with Smart Management Modules, up to 8 more loads can be 
managed as well, providing the most installation efficient power management options available.
