Product FAQs
8 answersWhat does the Y2 suffix mean in the BDA24020Y2 catalog number?
The Y2 suffix indicates that this 2-pole breaker is configured for an AC phase connection on the I-Line busbar stack.
Which panelboards are compatible with the BDA24020Y2 circuit breaker?
This breaker is designed exclusively for Square D I-Line power distribution panelboards and switchboards. It will not fit in standard QO or NQ load centers.
What wire sizes and materials are accepted by the load lugs?
The factory-installed mechanical lugs accept either copper or aluminum conductors ranging from 14 AWG to 2/0 AWG.
Can the BDA24020Y2 be used in DC power systems?
Yes, this breaker is dual-rated for both AC and DC applications. It carries an interrupting rating of 10 kAIC at 250VDC.
Is the BDA24020Y2 a direct replacement for older Square D breakers?
Yes, this PowerPacT B-frame breaker serves as a modern, direct replacement for legacy FA-frame breakers, such as the FA24020AC. It fits into the same I-Line panelboard space without requiring modifications.
How does this breaker mount into the panelboard?
It features an I-Line plug-in mounting design. The line side uses a shrouded plug-on jaw that stabs directly onto the panelboard bus, eliminating the need for line-side wire terminations.
What does the D in the BDA prefix represent?
In the Square D PowerPacT B-Frame series, the D indicates the specific interrupting capacity tier. For this model, it signifies an 18 kAIC rating at 480VAC and a 25 kAIC rating at 240VAC.
Does this breaker include a visual trip indicator?
Yes, PowerPacT B-frame breakers feature a Visi-Trip indicator for rapid fault identification, as well as an integral push-to-trip button in the cover to manually test the tripping mechanism.
