Built for industrial distribution, the Q221175AB is a 175-amp molded case circuit breaker featuring a dedicated AB phase connection. This 2-pole breaker utilizes Square D’s proven I-Line mounting system, allowing for rapid, plug-on installation into compatible I-Line panelboards. It delivers a 10kAIC interrupt rating at 120/240VAC and includes a Visi-Trip indicator for fast troubleshooting. For modern panel upgrades, this legacy Q2 frame has been replaced by the QBA221751 model.
