Product FAQs

7 answers
What does the "4" at the end of the QGA221004 catalog number indicate?

The "4" indicates that this 2-pole I-Line circuit breaker is factory-configured for a BC phase connection. For an AB phase connection, the correct catalog number is QGA221001.

Is the QGA221004 a direct replacement for older Square D Q2 series breakers?

Yes. The PowerPacT Q-frame circuit breakers, including the QGA221004, are designed as direct replacements for legacy Square D Q2 series I-Line circuit breakers.

What size and type of wire can be used with the load lugs on the QGA221004?

The standard load lugs accept wire sizes ranging from 4 AWG to 300 kcmil. They are dual-rated for use with both copper (Cu) and aluminum (Al) conductors.

How much mounting space does this 2-pole Q-frame breaker require in an I-Line panelboard?

The QGA221004 requires 3 inches of mounting space. Q-frame I-Line circuit breakers measure 1.5 inches in width per pole.

Can I install the QGA221004 in a Square D NQ or NF series panelboard?

No. The QGA221004 features an I-Line style plug-in connection and is exclusively compatible with Square D I-Line panelboards, such as HCN, HCM, HCW, and HCWM, as well as I-Line switchboards.

Is the QGA221004 suitable for use on a 208Y/120V AC electrical system?

Yes. While it has a maximum voltage rating of 240V AC, it is fully rated for use on 208Y/120V AC systems and provides a 65kA interrupting capacity at that voltage.

Does the QGA221004 provide GFCI or AFCI protection?

No. This is a standard thermal-magnetic circuit breaker designed for equipment overcurrent and short-circuit protection. It does not include Ground Fault Circuit Interrupter (GFCI) or Arc Fault Circuit Interrupter (AFCI) functionality.
