Square D PowerPact QDA221002 Q-Frame 2P 100A MCCB I-Line 80% AC
250A Frame | 100A | 2P | 25kA@240Vac | Thermal-Magnetic (Fixed)
The Square D PowerPact QDA221002 represents the Q-Frame series of compact 250A-class molded case circuit breakers, combining robust thermal-magnetic protection with versatile mounting options. This 2-pole device is rated at 100A with 240V AC voltage capability and an interrupting capacity of 25kA@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 QDA221002 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. Engineers and contractors rely on the QDA221002 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 3.00" W x 4.25" D with an approximate weight of ~3 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.
