Product FAQs
7 answersWhich panelboards accept the BDA34110Y circuit breaker?
The BDA34110Y is an I-Line mounting breaker designed exclusively for Square D I-Line Panelboards and I-Line Switchboards. It will not fit in standard QO, NQ, or NF series panels.
What wire gauge is required for the load lugs on the BDA34110Y?
The factory-installed load lugs accept wire sizes from 14 AWG up to 2/0 AWG. Both aluminum and copper (Al/Cu) conductors are supported.
Can I adjust the trip settings on the BDA34110Y?
No, this breaker uses a thermal-magnetic trip unit with fixed long-time (thermal) and fixed instantaneous (magnetic) settings. It does not have adjustable dials or a MicroLogic electronic trip unit.
Is the BDA34110Y suitable for 250VDC systems?
Yes, in addition to its AC ratings, this breaker is rated for 250VDC applications and provides a 10kA interrupting rating at that voltage.
What does the "Y" suffix mean in the BDA34110Y part number?
The "Y" indicates the breaker is rated for 480Y/277V AC systems. It is intended for use on solidly grounded wye electrical systems.
Can the BDA34110Y be used to replace older Square D breakers?
Yes, the PowerPacT B-Frame series is the designated replacement for legacy Square D F-Frame circuit breakers. In I-Line applications, the B-Frame maintains the same footprint to simplify retrofits.
How is the BDA34110Y secured to the panelboard bus?
The breaker uses isolated plug-on jaws on the line side that attach directly to the I-Line bus. It is then secured in place using a mechanical I-Line bracket mechanism to ensure a robust connection.
