Square D PowerPact QBL32090 Q-Frame 3P 90A MCCB Lug 80%
250A Frame | 90A | 3P | 10kA@240Vac | Thermal-Magnetic (Fixed)
The QBL32090 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 90A with 240V AC voltage capability and an interrupting capacity of 10kA@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 QBL32090 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. Ideal for branch circuit protection and similar applications, the QBL32090 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. Schneider Electric provides extensive technical documentation, installation instructions, and trip curve data for proper application and coordination. All PowerPact Q-frame devices meet NEMA AB-1 requirements and are built to withstand demanding commercial and industrial operating environments.
