Product FAQs
6 answers
What older Square D circuit breakers does the QGL32225 replace?
The PowerPacT Q-frame QGL32225 is a direct drop-in replacement for discontinued Square D Q2 Series breakers, including the Q23225.
Can I install the QGL32225 in an NQ panelboard?
Yes, but because it is a unit-mount breaker with non-removable lugs, it requires a specific adapter kit. For a main breaker application, use the NQMB2Q kit. For a sub-feed application, use the NQSFB2Q kit.
What is the recommended tightening torque for the lugs on the QGL32225?
The factory-installed lugs, which accept 4 AWG to 300 kcmil aluminum or copper wire, should be torqued to 248 lb-in (28 N.m).
What are the magnetic trip thresholds for this thermal-magnetic breaker?
The QGL32225 features a fixed magnetic trip with a hold current of 1200A and a tripping current of 2400A.
Does this breaker connect directly to the panelboard bus?
No. The QGL32225 is a unit-mount breaker with factory-installed lugs on both the line and load sides. When installed in a panelboard, it connects to the bus via cables rather than a direct busbar connection.
Is the QGL32225 rated for 100 percent continuous current?
No, this breaker has a standard 80 percent continuous current rating.
