Product FAQs

7 answers
What panelboards are compatible with the FA26070BC?

This breaker is designed exclusively for Square D I-Line power distribution panelboards and switchboards. It utilizes an I-Line plug-on connection and cannot be installed in standard NQ or NF panels.

What does the BC suffix indicate on the FA26070BC?

The BC suffix means this 2-pole breaker is factory-configured to connect to the B and C phases of the I-Line bus. It is important to verify your required phase arrangement before installation, as the jaw configuration is fixed.

What is the current-generation replacement for the FA26070BC?

The legacy Square D FA frame has been superseded by the PowerPact H-Frame series. Facilities upgrading their I-Line panelboards can typically use a 70A, 2-pole PowerPact H-Frame breaker as a modern substitute.

How does the FA26070BC mount into an I-Line panelboard?

The breaker features a plug-on design where the line-side jaws grip the I-Line bus bars directly. The load end is then secured to the panel backpan using a mounting screw.

Does the FA26070BC come with load-side lugs?

Yes, the breaker includes factory-installed load lugs that accept 14 AWG to 1/0 AWG copper or aluminum wire. The line side connects directly to the I-Line bus, so no line-side lugs are required.

Can the FA26070BC be used in direct current (DC) systems?

Yes, in addition to its AC ratings, this breaker is rated for up to 250VDC with a 10kA interrupting capacity. This makes it suitable for specific DC control and distribution circuits.

Are the trip settings on the FA26070BC adjustable?

No, this breaker features a fixed thermal-magnetic trip unit. The long-time and instantaneous (LI) protection settings are factory-calibrated and cannot be adjusted in the field.

    Great company

    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.

    Professional 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!

    As good as new

    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.
