Product FAQs

6 answers
What is the modern PowerPact replacement for the legacy FA22020AC?

Square D has transitioned from the legacy F-frame to the PowerPact B-frame series. The direct modern equivalent for this 20 Amp, 2-pole I-Line breaker is the PowerPact BDA240202.

What does the "AC" suffix indicate on this I-Line breaker?

The "AC" suffix specifies the busbar jaw configuration. It means this 2-pole breaker is factory-configured to connect specifically to the A and C phases of an I-Line panelboard.

Will this F-frame breaker fit in a standard Square D QO or Homeline load center?

No. The FA22020AC features an I-Line plug-on connection designed exclusively for commercial and industrial Square D I-Line panelboards and switchboards. It is not compatible with residential QO or Homeline enclosures.

Are the thermal and magnetic trip functions field-adjustable on this model?

No. The FA22020AC utilizes a fixed thermal-magnetic trip unit. Both the long-time overload protection and the instantaneous short-circuit protection are factory-calibrated and cannot be modified by the installer.

How does the line-side connection work on the FA22020AC?

The line side utilizes Square D's I-Line plug-on jaw mechanism, which snaps directly onto the panelboard's busbar. This eliminates the need for line-side cables, while the load side uses standard mechanical lugs for wire termination.

Can the FA22020AC be installed while the I-Line panelboard is energized?

While the I-Line plug-on design simplifies installation, NFPA 70E safety standards require the panelboard to be fully de-energized before installing or removing any circuit breaker to mitigate arc flash and shock hazards.

    Great company

    Ordered on a Saturday evening, paid for two day shipping and it arrived on time and in perfect condition. Would 100 percent be using this company going forward, beat out pricing and shipping times for all my local supply houses. Plus the staff were great to deal with.

    Professional Service

    So far, so good! The circuit breaker was installed along with a new compressor for our church AC, and everything is now working well.

    The company has been professional, dependable, and reputable throughout the process. I had a question after the installation, and it was answered immediately. I also appreciated that they followed up and asked for feedback to make sure the new part was working properly and that we were satisfied with the service.

    It’s refreshing to deal with a company that not only has quality products but also cares about its customers after the job is completed. I would definitely recommend them!

    As good as new

    The Square D FA32100 circuit breaker (refurbished) was as good as a new breaker, without exception. There was no wear and tear or any marks at all. It was basically new. It is an excellent choice and a great product without having to pay the cost of a new breaker.
