Overview
The Square D QBP22175TM is a PowerPact Q Series molded case circuit breaker rated at 175 amperes, 240V AC, 2-pole. Engineered for distribution panelboard applications, this breaker features thermal-magnetic trip technology for reliable overcurrent and short-circuit protection. The unit-mount lug configuration enables bottom-of-panel installation with lugs on both line and load sides. With an 80% continuous current rating, it is suitable for continuous-duty loads such as feeders and branch circuits serving industrial, commercial, and facility systems.
