Product FAQs
6 answersWhat is the modern replacement for the legacy FA22025AB circuit breaker?
The FA22025AB is part of the legacy Square D F-frame series. It is officially replaced by the modern PowerPacT B-frame series, specifically catalog number BDA24025Y1, which maintains the 25A rating and I-Line mounting compatibility.
What does the AB suffix mean in the FA22025AB catalog number?
The AB suffix indicates the phase connection. It specifies that this 2-pole I-Line circuit breaker is configured with jaws that connect directly to the A and B phases on the panelboard busbar.
How does the FA22025AB mount into the panelboard?
This breaker utilizes the Square D I-Line plug-on mounting system. The line side features plug-on jaws that attach directly to the busbar, allowing for fast installation in I-Line panelboards and switchboards without the need for busbar bolting.
Does the FA22025AB feature a visual trip indicator?
Yes, it includes the Square D Visi-Trip indicator. When the breaker trips due to an overcurrent or short circuit, a red flag appears in the window to help quickly identify the tripped unit within a crowded panel.
Can the FA22025AB be installed in standard QO or Homeline load centers?
No. The FA22025AB is an F-frame molded case circuit breaker designed exclusively for commercial and industrial Square D I-Line panelboards and switchboards. It is physically incompatible with residential QO or Homeline load centers.
What type of protection does the FA22025AB trip unit provide?
It features a thermal-magnetic trip unit with fixed long-time and instantaneous (LI) functions. The thermal element provides delayed protection against sustained overloads, while the magnetic element trips instantaneously in the event of a short circuit.

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.
- AHAnn H.Verified BuyerReviewingSquare D FA36100 - 100A 3 Pole Molded Case Circuit BreakerI recommend this productRated 5 out of 5 stars8/22/26Professional 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!
