Product FAQs
7 answersWhat does the "AC" suffix indicate on the FA26080AC breaker?
The "AC" suffix specifies the phase connection. It means this 2-pole I-Line breaker is factory-configured to connect to the A and C phases on the panelboard bus.
What is the modern replacement for the legacy FA26080AC?
The FA series is a legacy F-Frame breaker. The direct modern upgrade is the Square D PowerPact H-Frame, specifically catalog number HDA260802, which is fully compatible with I-Line panelboards.
Can the FA26080AC be installed in standard Square D load centers?
No. This breaker features an I-Line plug-on connection designed exclusively for Square D I-Line industrial panelboards and switchboards. It is not compatible with QO, Homeline, or NQ/NF panelboards.
Is the FA26080AC suitable for direct current (DC) systems?
Yes, alongside its AC ratings, this breaker is rated for up to 250VDC with a 10kAIC interrupting capacity, allowing it to be used in industrial DC distribution applications.
What wire sizes and materials are compatible with the FA26080AC lugs?
The standard factory lugs accept both copper (Cu) and aluminum (Al) conductors, accommodating wire gauges from 14 AWG up to 1/0 AWG.
Are the trip settings on the FA26080AC adjustable?
No. This breaker utilizes a standard thermal-magnetic trip unit with fixed thermal (long-time) and fixed magnetic (instantaneous) trip settings.
How can I visually identify if the FA26080AC has tripped?
This F-Frame breaker features a Visi-Trip indicator, which provides a clear visual confirmation when the breaker has tripped due to an overcurrent or short circuit event, improving safety and troubleshooting speed.

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!
