Socomec disconnect switches provide make-and-break power under load, and most styles are front, right-side, flange or direct-handle operable. The disconnect switches are available as nonfusible three-pole, nonfusible heavy-duty and enclosed nonfusible, as well as compact fusible and multipolar load switches that are rotary disconnect switches. Blown-fuse monitors detect fuse openings using a latching relay and a signaling LED. They can be mounted on a 35-mm DIN rail, on a back plate or next to the disconnect switch or on the door, or they can be mounted on the side of Fuserbloc 3861 series switches. The switches are UL-listed.
