Schneider Electric MO481111 Molded Case Circuit Breaker

Schneider Electric's Square D MO481111 Molded Case Circuit Breaker is an older 15‑amp protective device designed for 120/240‑volt AC circuits in distribution panels that accept MO‑series MCCBs. This MO481111 model—often referenced in legacy catalogs—belongs to the molded‑case family used to provide overcurrent protection in residential and light commercial installations where Square D equipment is installed. As a molded case circuit breaker, it interrupts current when an overload or short occurs, with a 15‑amp rating suitable for protecting standard branch circuits wired to typical residential loads; in secondary marketplaces, MO481111 is frequently listed as a 4‑pole configuration in 120/240 V service, reflecting its historical packaging and compatibility in multi‑wire or split‑phase installations. When sourcing a replacement, verify mechanical fit and panel compatibility with your specific Square D MO‑series enclosure and ensure the part number MO481111 matches the required rating and terminal configuration for your installation.
