Square D PowerPact QBL32080 Q-Frame 3P 80A MCCB Lug 80%
250A Frame | 80A | 3P | 10kA@240Vac | Thermal-Magnetic (Fixed)
Designed for branch circuit and feeder protection, the Square D QBL32080 Q-Frame circuit breaker delivers proven reliability with fixed thermal-magnetic trip technology. This 3-pole device is rated at 80A 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 QBL32080 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. With its combination of fixed thermal-magnetic protection and robust construction, the QBL32080 is an excellent choice for demanding electrical distribution applications requiring dependable overcurrent protection. Compatible with Q2-series enclosures including Q22200NS, Q22200NRB, Q23225NF, Q23225NS, and Q23225NRB for individual mounting applications. Field-installable accessories include handle padlock attachments (QBPA), service barriers (QSB2/QSB3), and mechanical interlock kits (QBMIK) for enhanced safety. The breaker operates reliably at ambient temperatures up to 40 degrees Celsius with correction factors available for higher temperature environments. The PowerPact Q-frame platform supports multiple termination options including lugs, studs, bus connections, and control wire taps for flexible installation.
