Product FAQs
7 answersWhat panelboards are compatible with the FA24070AC?
The FA24070AC is designed exclusively for use in Square D I-Line panelboards and switchboards. It features a factory-installed plug-in connection for the line side.
What is the modern replacement for the FA24070AC?
The legacy F-Frame FA24070AC is directly replaced by the newer PowerPact H-Frame HDA260702. The HDA260702 maintains the same 70A rating, 2-pole configuration, and AC phase connection for I-Line panels.
What does the AC suffix mean on this circuit breaker?
The AC suffix indicates the phase connection configuration. It means the breaker is factory-configured to connect to the A and C phases on the I-Line bus.
How much mounting space does this 2-pole breaker require in an I-Line panel?
As an F-Frame 2-pole breaker, the FA24070AC requires 3 inches of mounting space in an I-Line panelboard, which is 1.5 inches per pole.
Can I convert this I-Line breaker to a unit-mount configuration?
No, I-Line plug-in connectors are factory-installed and cannot be removed or converted to line-side lugs in the field. You must order a unit-mount specific breaker if line-side lugs are required.
Is the FA24070AC suitable for heating, air conditioning, and refrigeration equipment?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires HACR-type circuit protection.
Does this breaker provide a visual indication when it trips?
Yes, it features a Visi-Trip indicator. When the breaker trips, the handle moves to a center position and a highly visible red indicator appears, making it easy to identify the tripped breaker in a panel.

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.
