Square D PowerPact QGA32125 Q-Frame 3P 125A MCCB I-Line 80% ABC
250A Frame | 125A | 3P | 65kA@240Vac | Thermal-Magnetic (Fixed)
Designed for branch circuit and feeder protection, the Square D QGA32125 Q-Frame circuit breaker delivers proven reliability with fixed thermal-magnetic trip technology. This 3-pole device is rated at 125A with 240V AC voltage capability and an interrupting capacity of 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 QGA32125 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. With its combination of fixed thermal-magnetic protection and robust construction, the QGA32125 is an excellent choice for demanding electrical distribution applications requiring dependable overcurrent protection. A visible trip indication mechanism with three handle positions (ON, tripped, and OFF) provides clear visual feedback of the breaker's operating status. The integrated push-to-trip button allows manual tripping for maintenance and testing as part of a regular preventive maintenance program. Compatible with Q2-series enclosures including Q22200NS, Q22200NRB, Q23225NF, Q23225NS, and Q23225NRB for individual mounting applications. The PowerPact Q-frame platform supports multiple termination options including lugs, studs, bus connections, and control wire taps for flexible installation.
