Product FAQs

6 answers
What does the BC suffix indicate on the FA22050BC catalog number?

The BC suffix specifies the phase connection for the I-Line bus. This breaker is factory-configured to plug into the B and C phases of a Square D I-Line panelboard.

What panelboards accept the FA22050BC circuit breaker?

This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It utilizes an I-Line style plug-in connection and cannot be installed in standard load centers like QO or Homeline.

What wire sizes are supported by the terminals on the FA22050BC?

The standard lugs accommodate 14 to 1/0 AWG copper wire, or 12 to 1/0 AWG aluminum wire.

Is the FA22050BC suitable for direct current (DC) systems?

Yes, in addition to its 240VAC rating, this breaker is rated for up to 250VDC applications with a 10kA interrupting capacity.

Are the trip settings adjustable on the FA22050BC?

No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time (thermal) and instantaneous (magnetic) trip functions are factory-set and non-adjustable.

Is the FA22050BC a current production model?

The FA22050BC belongs to the legacy Square D F-Frame series, which has largely been superseded by the newer PowerPact series. However, it remains a direct replacement for maintaining existing I-Line distribution systems.

    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!
