Product FAQs
8 answersWhat does the "1" suffix mean in the QGA221501 catalog number?
The "1" suffix indicates an AB phase connection. This specifies which two bus bars the 2-pole breaker will draw power from when installed in a 3-phase I-Line panelboard.
What panels accept the QGA221501 breaker?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It uses a plug-on jaw configuration that connects directly to the I-Line bus structure.
Do I need extra hardware to mount this breaker to the bus?
No. The I-Line plug-on design includes integrated jaws that snap directly onto the panelboard bus. No separate mounting brackets or bus connectors are required.
What wire sizes do the load lugs on the QGA221501 accept?
The factory-installed load lugs accommodate aluminum or copper conductors ranging from 4 AWG to 300 kcmil.
Is the PowerPacT Q-frame a replacement for older Square D breakers?
Yes, PowerPacT Q-frame breakers are direct replacements for legacy Square D Q2 series circuit breakers.
What does the "G" in the QGA frame designation represent?
The "G" indicates the interrupting capacity tier of the breaker. For this Q-frame model, it signifies a 65kA short-circuit current rating at 240VAC.
Can the QGA221501 be used on a 208Y/120V system?
Yes. While it has a maximum voltage rating of 240VAC, it is fully compatible with 208Y/120VAC systems and maintains its 65kA interrupting rating at that voltage.
Can I adjust the trip settings on the QGA221501?
No, this breaker features a non-interchangeable thermal-magnetic trip unit with fixed long-time and fixed instantaneous trip functions.
