Square D QOM22225NF Circuit Breaker Enclosure

Square D QOM22225NF is a QOM2 series circuit-breaker enclosure designed to house a 2-pole QO breaker up to 225 A in flush-mount, indoor installations. The enclosure is NEMA 1 rated (with NEMA 3R variants available separately) and UL listed, offered in metallic and non-metallic options. Constructed from steel, it measures roughly 8.55 in wide, 3.95 in deep, and 23.92 in high, providing space to mount a standard QO two-pole breaker with wiring contained behind the door. It is intended for use as service equipment in locations where the current code does not require service barriers, but it is not service-entrance rated where barriers are mandated. The QOM2 enclosure accepts QO-type breakers (to be ordered separately) and its flush-mount design supports a compact, accessible disconnect solution in control rooms or distribution panels.
