Product FAQs
6 answersWhat is the modern replacement for the legacy Square D FA22070AC circuit breaker?
The FA22070AC is a legacy F-Frame breaker. Its direct modern replacement is the Square D PowerPacT B-Frame series, specifically catalog number BDA24070Y2, which matches the 70A rating, 2-pole configuration, I-Line mounting, and A-C phase connection.
What does the "AC" suffix indicate on the FA22070AC catalog number?
The "AC" suffix specifies the phase connection. It indicates that this 2-pole breaker is factory-configured to connect to the A and C phases on the busbar of a Square D I-Line panelboard or switchboard.
How does the FA22070AC connect to the panelboard?
This breaker features an I-Line style plug-in mounting design. It uses blow-on plug-on connectors that grip the panelboard busbars tightly, allowing for quick and secure installation in compatible Square D I-Line panelboards and switchboards.
Are the trip settings on the FA22070AC adjustable?
No, the FA22070AC features fixed thermal and fixed magnetic trip elements. They are factory-calibrated for an average ambient temperature of 40 degrees Celsius and cannot be adjusted in the field.
Is the FA22070AC compatible with standard QO or Homeline load centers?
No. The FA22070AC is an F-Frame molded case circuit breaker with an I-Line plug-in mounting style. It is exclusively designed for commercial and industrial Square D I-Line panelboards and switchboards, not residential load centers.
What type of protection does the FA22070AC provide for electrical systems?
It utilizes a thermal-magnetic trip unit to deliver LI protection. The thermal element provides Long-Time protection against sustained overloads, while the magnetic element provides Instantaneous protection to quickly clear short circuits.

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.
