Product FAQs

5 answers
What type of panelboards accept the QJA32110?

This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It utilizes the I-Line plug-in mounting system, which allows for quick installation and phase balancing without the need for bolted connections on the bus.

What does the J in the QJA32110 catalog number signify?

In the Square D PowerPacT Q-frame nomenclature, the J indicates the interrupting rating tier. For this specific breaker, it signifies a high interrupting capacity of 100kA at 240V AC.

Are the trip settings on this breaker adjustable?

No, the QJA32110 features a fixed thermal magnetic trip unit. Both the long-time thermal overload protection and the instantaneous magnetic short-circuit protection are factory set and cannot be adjusted in the field.

What are the acceptable wire sizes for the lugs on this breaker?

The factory-installed lugs accept both aluminum and copper conductors ranging from 4 AWG to 300 kcmil. Always apply the manufacturer-specified torque when terminating conductors.

Can this breaker replace older Q-frame I-Line breakers?

Yes, the QJA32110 is part of the PowerPacT Q-frame family and serves as a direct replacement for older Square D Q-frame I-Line breakers with matching amperage and interrupting ratings.
