Product FAQs
7 answersIs the FA24030AB still actively manufactured by Square D?
No, the Square D FA frame series is a legacy product and is no longer actively manufactured. The PowerPact B-frame series serves as the modern equivalent. The direct drop-in replacement for this specific breaker is the BDA260301.
What does the AB suffix mean in the FA24030AB catalog number?
The AB suffix indicates the factory-configured phase connection for the I-Line bus. This specific breaker is designed to connect to Phase A and Phase B in the panelboard.
Can I install the FA24030AB in a standard QO load center?
No, this breaker features an I-Line plug-in mounting style and is designed exclusively for use in Square D I-Line panelboards and switchboards. It is not compatible with standard QO or Homeline load centers.
How does the I-Line mounting connection work on the FA24030AB?
The I-Line plug-in design utilizes a blow-on connection system. During high-fault conditions, the magnetic forces cause the jaws to grip the panelboard busbars tighter, which reduces the risk of arcing and ensures a secure electrical connection.
What is the difference between the FA24030AB and an FH equivalent?
The FA frame is a standard-interrupting breaker, providing an 18kAIC rating at 480VAC. The FH frame is the high-interrupting version, designed for systems that require a higher 25kAIC rating at 480VAC.
Are the thermal and magnetic trip settings adjustable on this breaker?
No, the FA24030AB features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous trip functions are factory-calibrated for a 30A continuous load and cannot be adjusted in the field.
What is the purpose of the instantaneous trip function on this breaker?
The instantaneous magnetic trip function is designed to react immediately to severe short circuits. It bypasses the thermal delay to open the circuit instantly, protecting downstream equipment and wiring from catastrophic fault currents.

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!

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.
