Product FAQs
7 answersWhat phase connection does the QBA222253 use for I-Line panelboards?
This specific model features a BA phase connection for mounting directly onto the I-Line bus stack.
What is the recommended lug tightening torque for this 225A Q-Frame breaker?
The load side lugs require a tightening torque of 248 lb-in (28 N.m) when terminating 4 AWG to 300 kcmil aluminum or copper wire.
Can the QBA222253 replace older Square D circuit breakers?
Yes, this PowerPacT Q-Frame breaker serves as a direct, modernized replacement for legacy Q22225 units in existing I-Line switchboards and panelboards.
Will this breaker fit in a standard QO or NQ load center?
No, the QBA222253 is designed exclusively for Square D I-Line panelboards and switchboards. It utilizes a specialized plug-on bracket and will not fit standard residential or NQ commercial load centers.
Are there higher interrupting rating alternatives to the QBA222253?
Yes, if your system requires a higher fault current rating than 10kAIC at 240VAC, you can upgrade to the QDA (25kAIC), QGA (65kAIC), or QJA (100kAIC) series Q-Frame I-Line breakers.
How does the I-Line connection work on the QBA222253?
The breaker features a plug-on line side that snaps directly onto the I-Line bus stack, eliminating the need for line-side mounting hardware, while the load side uses standard mechanical lugs.
How can I manually test the trip mechanism on this breaker?
The QBA222253 includes an integrated push-to-trip button on the cover, allowing you to manually test the mechanical operation of the trip mechanism. It also features a Visi-Trip indicator for clear visual identification of a tripped status.
