Product FAQs
7 answersWhat panelboards are compatible with the QDA221754 circuit breaker?
This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It features an I-Line style plug-in connection that mounts directly to the bus assembly.
Are the load-side lugs on the QDA221754 rated for aluminum wire?
Yes, the factory-installed lugs are dual-rated for both copper and aluminum conductors ranging from 4 AWG to 300 kcmil.
What is the difference between the QDA, QBA, QGA, and QJA frame breakers?
The second letter in the prefix indicates the interrupting rating at 240VAC. The QBA is rated for 10kAIC, the QDA for 25kAIC, the QGA for 65kAIC, and the QJA for 100kAIC. They share the same physical dimensions and I-Line mounting.
Can I use the QDA221754 in a 480V or 600V electrical system?
No. The PowerPacT Q-frame series is rated for a maximum of 240VAC. It is not suitable for 480V or 600V applications.
Does this breaker require a separate mounting bracket for installation?
No. As an I-Line plug-in breaker, it connects directly to the panelboard bus without the need for additional mounting hardware or brackets.
Is the QDA221754 a direct replacement for older Q2 series breakers?
Yes. The Square D PowerPacT Q-frame circuit breakers are direct replacements for legacy Q2 series devices, fitting into the same I-Line panelboard spaces.
Which phase connection is this 2-pole breaker configured for?
The number 4 at the end of the QDA221754 catalog number indicates it is factory-configured for a BC phase connection in an I-Line panelboard.
