Eaton Automatic Transfer Switch Breaker Operation

Number of Poles for Switch


Automatic transfer switches offer a safe, quick, and convenient method of swapping from utility power to auxiliary or portable power sources in the event of an emergency. When an outage occurs the automatic switch will shift to emergency power sources within a fraction of a second, minimizing safety risks and downtime.

The Eaton automatic transfer switch with breaker operation allows for smooth transition so that your business can remain productive and safe in any event, planned or unanticipated. The product is available in a range of 200-1000 amps per your needs, with the 1,000 amp product offering ground fault protection in addition to standard protections. The switch also features both three and four pole configurations.

A breaker-operated ATC-300+ Controller allows for greater flexibility and control, allowing businesses to control switching parameters as well as threshold ranges.

Wall Mounted NEMA 1, 3R, and 4X enclosures offer additional defense against snow, rain, sleet, and high winds and are capable of effectively protecting products both indoors and outdoors. The 4X enclosure also features additional resistance to corrosive materials common to industrial workplaces.
