Product FAQs
7 answersWhat does the BC suffix indicate on the FA22070BC circuit breaker?
The BC suffix specifies the phase connection configuration. The jaws on this 2-pole breaker are positioned to connect exclusively to the B and C phases on a Square D I-Line busbar, allowing for precise load balancing across the panel.
What is the modern replacement for the legacy FA22070BC breaker?
The legacy F-frame FA22070BC has been superseded by the newer PowerPact B-frame series. The direct replacement for I-Line panelboards is catalog number BDA24070Y4.
What wire gauge range is supported by the terminals on the FA22070BC?
The standard lug terminals accommodate 14 to 1/0 AWG copper conductors or 12 to 1/0 AWG aluminum conductors.
Can I install the FA22070BC in a standard Square D QO load center?
No. The FA22070BC features an I-Line plug-in mounting style and is only compatible with Square D I-Line panelboards and switchboards. It will not fit in QO or Homeline residential load centers.
How can I visually identify if the FA22070BC has tripped?
This breaker features a Visi-Trip indicator. When a fault causes the breaker to trip, a highly visible red indicator appears in the window, allowing operators to quickly locate the tripped circuit in a crowded panelboard.
Is the FA22070BC rated for direct current (DC) systems?
Yes, this thermal-magnetic breaker is rated for use in 250VDC systems, where it provides an interrupting capacity of 5kAIC.
What type of protection does the FA22070BC trip unit provide?
The breaker is equipped with a fixed thermal-magnetic trip unit. It provides long-time (thermal) protection for standard overloads and instantaneous (magnetic) protection for 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.
