Product FAQs
5 answersIs the QBL32175 compatible with Square D I-Line panelboards?
No. This is a unit-mount circuit breaker equipped with feed-thru lugs for cabled applications. It will not plug into an I-Line bussing system.
What older Square D circuit breakers does the QBL32175 replace?
The PowerPacT Q-frame unit-mount breaker is a direct replacement for discontinued Square D Q2 series breakers, such as the Q23175. It shares the same mounting footprint, door trim, and handle location.
Does the QBL frame offer higher interrupting ratings if my system requires it?
Yes. While the QBL model provides a 10kA interrupting rating at 240VAC, the identical footprint is available in QD (25kA), QG (65kA), and QJ (100kA) versions for systems with higher available fault currents.
Does this breaker feature a push-to-trip button for mechanical testing?
Yes, PowerPacT Q-frame breakers include an integral push-to-trip button on the front cover. This allows you to manually trip the mechanism and verify proper operation during maintenance.
Can the QBL32175 be installed on a DIN rail?
Out of the box, it is designed for free-standing unit mounting on a backpan or baseplate. However, you can mount it to a DIN rail by purchasing a separate compatible DIN rail adapter kit.
