Schneider Electric QO2100BN Circuit Breaker Enclosure

Schneider Electric's Square D QO2100BN circuit breaker enclosure is a 100 A, 120/240 V, single‑phase, two‑space indoor enclosure in the QO family designed to house QO‑series breakers. Available variants include QO2100BNF (flush‑cover), QO2100BNS (surface‑cover), and QO2100BNRB (surface variant), all UL listed and rated for NEMA 1 environments. The enclosure measures about 13.19 in wide by 5.9 in deep by 3.4 in high and is intended for indoor use where a compact two‑space distribution solution is needed. It provides provisions for double‑pole installations and can accept QOM2 breakers with factory‑installed accessories, enabling flexible configurations for two‑pole or two single‑pole arrangements depending on interior trim. This enclosure is commonly used in residential or light commercial installations as a protective housing for branch‑circuit protection, with compatible 2‑pole breakers such as the QO series used to protect feeders or branch circuits up to 100 A.
