The Square D QDM32125 is a 3-pole molded case circuit breaker from the Powerpact family, designed for thermal-magnetic protection against overloads and short circuits in industrial power distribution systems. It is rated for 125A continuous current at 240VAC, 3-phase, with an interrupting capacity of 25kA at 240V, and features LI (Long-Time and Instantaneous) trip functions for coordinated protection. This bolt-on breaker uses a Q Frame size, weighs 4 lb, and is constructed for reliable performance in panelboards and switchboards. It complies with UL and CSA standards for molded case circuit breakers. Typical applications include motor control centers, lighting panels, and branch circuit protection in commercial and industrial facilities.
