Product FAQs
6 answersWhat does the "A" suffix in the FA14080A catalog number indicate?
The "A" suffix indicates that this 1-pole breaker is configured to connect specifically to the A-phase jaw of a Square D I-Line panelboard bus.
Is the Square D FA14080A still in active production, or is there a direct replacement?
The FA frame is a legacy molded case circuit breaker. For modern upgrades or replacements, Square D recommends the PowerPacT B-Frame series, specifically the BDA140801, which also features an I-Line plug-on connection.
What wire sizes and materials are compatible with the load-side lugs on the FA14080A?
The factory-installed load-side lugs are dual-rated for both copper and aluminum conductors. They accept copper wire from 14 AWG to 1/0 AWG, and aluminum wire from 12 AWG to 1/0 AWG.
Can the FA14080A be used in DC voltage applications?
Yes, in addition to its standard AC ratings, this thermal-magnetic breaker is rated for 125VDC applications with an interrupting capacity of 10 kAIC, making it suitable for specific control or battery circuits.
Which panelboards are designed to accept the FA14080A circuit breaker?
This breaker features an I-Line style plug-in connection on the line side and is exclusively designed for use with Square D I-Line panelboards and switchboards. It cannot be used in standard load centers or NQ/NF panels.
What type of trip unit is installed in the FA14080A?
It features a fixed thermal-magnetic trip unit that provides both long-time and instantaneous (LI) overcurrent protection. The thermal and magnetic trip points are factory-fixed and non-adjustable.

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.
