Product FAQs
6 answersIs the Square D FA32020 obsolete, and what is the direct replacement?
Yes, the FA-frame series is a legacy product. The official modern replacement from Schneider Electric is the PowerPacT B-frame, specifically catalog number BDA34020, which fits the same I-Line panelboards.
What is the difference between the FA32020 and the FAL32020?
The FA32020 features an I-Line plug-on connection on the line side for use in Square D I-Line panelboards. The FAL32020 is a lug-to-lug circuit breaker designed for individual enclosures or control panels. They are not interchangeable.
How does the FA32020 connect to the panelboard?
It uses an I-Line style plug-in connection. The line side of the breaker plugs directly into the busbar stack of a compatible Square D I-Line panelboard, while the load side uses traditional mechanical lugs for wire connections.
Does the FA32020 feature a visual trip indicator?
Yes, it includes a Visi-Trip indicator. When the breaker trips due to an overcurrent or short circuit, the handle snaps to a center position and a highly visible red indicator appears to help quickly identify the tripped circuit.
Is the FA32020 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 this specific protection.
Can the FA32020 be reverse fed?
No. Because it features an I-Line plug-on connection designed specifically for the line-side busbar of a panelboard, it cannot be reverse fed.

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.
