Product FAQs

6 answers
What panelboards are compatible with the FA24015CA breaker?

The FA24015CA is a plug-in style breaker designed exclusively for Square D I-Line panelboards and switchboards. It cannot be used in standard QO, Homeline, or NQ/NF series panels.

What does the CA suffix mean in the FA24015CA catalog number?

For Square D I-Line breakers, the CA suffix indicates the specific phase connection. This 2-pole breaker is factory-configured to connect to the C and A phases of the panelboard's 3-phase bus.

Is the FA24015CA rated for use in direct current (DC) systems?

Yes, in addition to its AC ratings, this breaker is rated for DC applications up to 250VDC, where it provides an interrupting capacity of 10kAIC.

What wire sizes and materials are supported by the FA24015CA lugs?

The standard mechanical lugs on this breaker accept 14 AWG to 1/0 AWG copper (Cu) wire, or 12 AWG to 1/0 AWG aluminum (Al) wire.

Do I need a separate mounting kit to install the FA24015CA?

No. As an I-Line breaker, it features a plug-in mounting design that connects directly to the I-Line bus assembly. No additional mounting hardware or brackets are required.

Are the trip settings on the FA24015CA adjustable?

No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time (thermal) overload protection and instantaneous (magnetic) short-circuit protection are factory-set 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!
