Product FAQs
8 answersWhich panelboards accept the Square D QGA221502 circuit breaker?
This breaker is specifically designed for group-mounted construction in Square D I-Line panelboards and switchboards. It uses an I-Line style plug-in connection on the line side.
What phase connection does the QGA221502 use?
The 2 at the end of the catalog number indicates this 2-pole breaker is factory configured for an AC phase connection on the I-Line bus.
What are the wire size requirements for the load side lugs on the QGA221502?
The box-type lugs accommodate 4 AWG to 300 kcmil aluminum or copper conductors.
How does the QGA221502 differ from QBA or QDA breakers?
The G in the catalog number designates a 65kA at 240V AC interrupting rating. QBA and QDA models share the same physical footprint but have lower interrupting ratings of 10kA and 25kA respectively.
Is the QGA221502 a suitable replacement for older Q2 series breakers?
Yes, the PowerPacT Q-frame is the direct replacement for legacy Square D Q2 series devices. Ensure the amperage, voltage, and phase connection match your existing breaker.
Does this breaker require a separate mounting bracket for I-Line panels?
No, the QGA221502 features an integrated I-Line shroud on the ON end for direct plug-in mounting to the panelboard bus.
What type of protection does the QGA221502 trip unit provide?
It includes a fixed thermal-magnetic trip unit that provides long-time (overload) and instantaneous (short circuit) protection. The trip elements are non-interchangeable.
Does the QGA221502 include a mechanism to manually test the trip function?
Yes, all PowerPacT Q-frame circuit breakers feature an integral push-to-trip button on the cover to manually trip the breaker and verify the mechanism is operating correctly.
