Product FAQs

6 answers
What does the Y1 suffix indicate on the BDA24090Y1 breaker?

The Y1 suffix specifies that this 2-pole I-Line breaker is factory-configured for an AB phase connection within the panelboard bus.

Which legacy Square D breakers does the BDA24090Y1 replace?

This PowerPacT B-frame breaker is the direct modern replacement for obsolete 90A, 2-pole FA24090 and FA24090AB circuit breakers used in I-Line panelboards.

Can the BDA24090Y1 be installed in standard QO or Homeline load centers?

No, this breaker features an I-Line plug-in connection. It is strictly designed for Square D I-Line panelboards and switchboards, and will not fit in residential load centers.

Does the BDA24090Y1 support DC voltage applications?

Yes, in addition to its AC ratings, this thermal-magnetic breaker is rated for 250VDC systems, providing a 10kAIC interrupting capacity for DC circuits.

Are the lugs on the BDA24090Y1 rated for both aluminum and copper conductors?

Yes, the factory-installed lugs accept either aluminum or copper wire ranging from 14 AWG to 2/0 AWG.

Does the BDA24090Y1 feature an adjustable trip unit?

No, this breaker is equipped with a fixed thermal-magnetic trip unit (LI), meaning both the long-time and instantaneous trip settings are factory-set and non-adjustable.

    Super Breakers had the breakers I needed in stock at a fair price and shipped & delivered in an expedited fashion. They are my go-to guys for hard to find breakers.

    Installed & working

    Ordered this from SuperBreakers when local vendors were quoting me 25%+.

    So I got a refurbished version of this breaker.

    It is installed and working.

    Also, service was great.

    Thank you SuperBreakers!
