Product FAQs
7 answersWhat type of panelboards accept the FA22080AC circuit breaker?
The FA22080AC is designed exclusively for Square D I-Line panelboards and switchboards. It features a specialized plug-in mounting bracket that engages directly with the I-Line bus stack.
What does the AC suffix mean in the FA22080AC catalog number?
In Square D I-Line breakers, the suffix indicates the specific busbar phase connection. The AC designation means this 2-pole breaker is factory-configured to connect to the A and C phases of the panelboard.
How does the thermal-magnetic trip unit in the FA22080AC operate?
This breaker utilizes a fixed thermal-magnetic mechanism for LI (Long-Time and Instantaneous) protection. The thermal component responds to sustained overloads by heating and tripping the breaker, while the magnetic component reacts immediately to high-current short circuits.
Can the FA22080AC be installed in a standard residential load center?
No. This is a commercial-grade F-frame breaker with an I-Line plug-in connection. It is not compatible with standard residential load centers like the Square D QO or Homeline series.
Is the FA22080AC considered a current or legacy breaker?
The FA series is a legacy molded case circuit breaker family from Square D. While newer panelboards may use updated breaker frames, the FA22080AC remains a direct drop-in replacement for existing I-Line systems requiring an 80A, 2-pole F-frame breaker.
Does the FA22080AC require a separate mounting hardware kit?
No. As an I-Line style plug-in breaker, the FA22080AC features integrated mounting jaws that attach directly to the panelboard busbar. No additional mounting hardware kits or strap kits are required for installation.
Can the FA22080AC be used in DC applications?
Yes, this breaker is rated for use in DC systems up to 250VDC, where it provides an interrupting capacity of 5kA. It is also rated for 10kA at 240VAC for standard alternating current applications.

- 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!
