Product FAQs
7 answersWhat panelboards are compatible with the QBA32110 circuit breaker?
This breaker features an I-Line style plug-in connection and is designed exclusively for use in Square D I-Line panelboards and switchboards. It is not compatible with standard QO, Homeline, or NQ panelboards.
Can the QBA32110 replace older Square D circuit breakers?
Yes, the PowerPacT Q-frame QBA32110 serves as a direct drop-in replacement for legacy Square D Q23110 breakers previously used in I-Line panelboards.
What does the B in the QBA32110 part number signify?
The B indicates the interrupting rating tier for this PowerPacT Q-frame breaker, which is 10 kA at 240 VAC. If your system requires a higher fault current rating, you must upgrade to a QDA (25 kA), QGA (65 kA), or QJA (100 kA) breaker.
Are the lugs on the QBA32110 rated for both aluminum and copper wire?
Yes, the factory-installed lugs are AL/CU rated, accepting either aluminum or copper conductors from 4 AWG up to 300 kcmil.
Does the QBA32110 require a separate mounting kit for installation?
No, this breaker features an integrated I-Line plug-on bracket that engages directly with the busbar stack in an I-Line panelboard, requiring no additional mounting hardware or sub-feed lug kits.
Can I use the QBA32110 on a 480V or 600V electrical system?
No, the PowerPacT Q-frame series is rated for a maximum of 240 VAC. It cannot be used in 480V or 600V applications. For higher voltage systems, a different frame size like the H-frame or J-frame is required.
How does the QBA32110 indicate a tripped condition?
The breaker features a center-tripped handle position that provides a clear visual indication when the thermal-magnetic trip unit has operated due to an overload or short-circuit fault.
