Panel mount single-pole breakers with stud terminals on the back. Ring terminals on the wire are required. Breakers mount from the front with two small screws. 10A- 125A breakers are 1 inch wide. 175A and 250A breakers are 1.5 inches wide

Use these breakers in the side knockouts of the old Xantrex/Trace DC disconnect, and in the large breaker spaces in the OutBack FLEXware 500/1000 enclosures.

The panel-mount 175A/250A breakers are also used in the Xantrex XW distribution panel.
