Square D Q2M2125MT Molded Case Circuit Breaker

Square D Q2M2125MT is a two-pole molded case circuit breaker rated for 125 A at 240 V AC (2P, 1PH), part of Schneider Electric’s Square D Q2M family. This bolt-on, top-mounted device uses load-side lug terminals and a thermal-magnetic trip mechanism to protect feeders and branch circuits, offering an interrupting rating of 10 kA at 240 VAC along with long-time and instantaneous (LI) trip functions. Designed for panels that accept Q2M breakers, the unit provides compact, high-current protection for commercial or light industrial electrical systems where space is at a premium and fast fault interruption is essential. The molded-case construction and 125 A, 2P configuration make it well suited for feeders or branch circuits in applications such as lighting, HVAC equipment, and general power distribution within control panels and distribution boards that accommodate Square D Q2M devices. This model is commonly used as a main or sub-feed protective device in spaces where reliable bolt-on installation is required.
