The QJA32175 is a PowerPact Q-Frame molded case circuit breaker from Schneider Electric's Square D product line, designed for reliable overcurrent protection in 240V AC distribution systems. This 3-pole device is rated at 175A with 240V AC voltage capability and an interrupting capacity of 100kA@208Y/120Vac, 65kA@240Vac. It features fixed thermal-magnetic trip elements in each pole, providing both overload (thermal) and short-circuit (magnetic) protection calibrated at 40 degrees Celsius ambient temperature, rated at 80% continuous current per NEC Article 240.6. The QJA32175 is featuring I-Line plug-in mounting for rapid installation and maintenance in Square D I-Line panelboards and switchboards. This device is UL 489 listed, CSA C22.2 No.5 certified, and NOM approved for use across North American installations, with an over-center toggle mechanism providing quick-make quick-break operation and trip-free functionality. Ideal for branch circuit protection and similar applications, the QJA32175 delivers the proven reliability and performance that engineers expect from the PowerPact platform. Physical dimensions of 6.47" H x 4.50" W x 4.25" D with an approximate weight of ~4 lbs ensure compatibility with standard enclosures and panelboards. The PowerPact Q-frame platform supports multiple termination options including lugs, studs, bus connections, and control wire taps for flexible installation. Compatible with Q2-series enclosures including Q22200NS, Q22200NRB, Q23225NF, Q23225NS, and Q23225NRB for individual mounting applications.
