Product FAQs
6 answersWhat does the "C" suffix indicate in the FA14015C catalog number?
The "C" signifies that this 1-pole breaker is factory-configured with a Phase C jaw connection. This specific jaw alignment dictates which phase the breaker connects to when installed into a Square D I-Line panelboard.
Is the Square D FA frame series still in active production?
No, the FA frame is a legacy molded case circuit breaker series. For modern system upgrades, Schneider Electric replaced the FA series with the PowerPact H-Frame series, which is also compatible with I-Line panelboards.
Can I install the FA14015C in a standard QO load center?
No, the FA14015C is an F-Frame molded case circuit breaker designed exclusively for industrial and commercial I-Line panelboards. It will not fit in residential QO or Homeline load centers.
Are the trip units on the FA14015C interchangeable?
No, this FA frame breaker utilizes a sealed construction with a non-interchangeable thermal-magnetic trip unit. The long-time and instantaneous trip settings are fixed and cannot be modified in the field.
Is the FA14015C suitable for HVAC applications?
Yes, this breaker is HACR rated, making it approved for use with heating, air conditioning, and refrigeration equipment motor loads.
How does the I-Line plug-in connection work on the FA14015C?
The I-Line plug-in design allows the breaker jaws to connect directly onto the panelboard bus stack. The breaker is then secured to the backpan with a mounting screw, eliminating the need for cabled bus connections and reducing installation time.

- 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.
