Schneider Electric Q2B32125H I-Line Circuit Breaker

Schneider Electric's Square D Q2B32125H I-Line circuit breaker is a 125-amp, three-pole device designed for 240-volt three-phase service, delivering reliable overcurrent protection for feeders and branch circuits in commercial or light-industrial power distributions. Engineered for I-Line mounting, it installs quickly in compatible Schneider Electric panelboards using a plug-in connection, simplifying replacement and maintenance in busy electrical rooms. This unit is part of the I-Line family of breakers, which use a dedicated bus interface and standardized footprint to support compact, modular protection solutions in panelboard systems. With its three-pole construction, it interrupts all phases simultaneously to secure a balanced shutdown during fault conditions in 240 VAC networks. Designed for use wherever three-phase protection at 240 V is required, the Q2B32125H provides a straightforward, compatible option for upgrading or expanding protected feeder circuitry in facilities that rely on Schneider Electric's I-Line hardware. The model number Q2B32125H identifies the 125 A rating, 3-pole, 240 V configuration within the I-Line line for quick cross-reference with panelboard inventories.
