Square D PowerPact QBL32000S22 Q-Frame 3P 225A Automatic Switch
250A Frame | 225A | 3P | 10kA@240Vac | Magnetic Only
Schneider Electric's Square D QBL32000S22 PowerPact Q-Frame automatic switch provides magnetic-only trip protection for switching and disconnect applications in power distribution systems. This 3-pole device is rated at 225A with 480V AC voltage capability and an interrupting capacity of 10kA@240Vac. It features a magnetic-only trip mechanism with a factory-set 4500A instantaneous trip point, providing short-circuit protection without thermal overload sensing, rated at 225A continuous current. The QBL32000S22 is configured with box-type lug connections accommodating 4 AWG-300 kcmil Al/Cu conductors for reliable cable termination. 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. Engineers and contractors rely on the QBL32000S22 for its proven track record of reliability, ease of installation, and comprehensive protection capabilities in low-voltage systems. The breaker operates reliably at ambient temperatures up to 40 degrees Celsius with correction factors available for higher temperature environments. 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. Field-installable accessories include handle padlock attachments (QBPA), service barriers (QSB2/QSB3), and mechanical interlock kits (QBMIK) for enhanced safety. A visible trip indication mechanism with three handle positions (ON, tripped, and OFF) provides clear visual feedback of the breaker's operating status.
