Product FAQs
8 answersWhat panelboards accept the Square D FA22090AB circuit breaker?
This breaker is specifically designed to plug directly into Square D I-Line panelboards and switchboards. It is not compatible with standard QO or NQ panels.
What does the AB suffix indicate on the FA22090AB catalog number?
The AB suffix specifies the phase connection. It means the breaker is factory-configured to connect to the A and B phases on the I-Line bus system.
What is the modern replacement for the obsolete FA22090AB?
The legacy FA frame has been discontinued by Schneider Electric. The direct modern replacement for this 240V, 90A I-Line breaker is the PowerPact B-frame series, specifically the BDA240901 model.
How is the FA22090AB installed into an electrical panel?
It features an I-Line plug-on design that connects directly to the panelboard bus on the line side, eliminating the need for bolt-on hardware. The load side utilizes standard mechanical lugs for wire connections.
Does the FA22090AB provide adjustable trip settings?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time thermal protection and the instantaneous magnetic protection are factory set and cannot be adjusted in the field.
Is the FA22090AB rated for direct current applications?
Yes, in addition to its 240V AC rating, this breaker is rated for use in 250V DC systems, where it provides a 5kA interrupting capacity.
What type of protection does the FA22090AB offer?
It utilizes a thermal-magnetic trip mechanism that provides dual-mode protection. The thermal element guards against sustained overloads, while the magnetic element responds immediately to short circuits.
Is the FA22090AB suitable for HVAC equipment?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires dedicated overcurrent protection.

- 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!

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.
