Part of the legacy F-frame series, this 15-amp molded case circuit breaker provides reliable thermal-magnetic protection for commercial and industrial facilities. It features a factory-configured B-C phase connection for specific load balancing requirements. Designed for seamless integration, the unit installs into Square D I-Line panelboards and switchboards.
What type of panelboards is the FA26015BC compatible with?
This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It features an I-Line style plug-in connection that mounts directly to the busbar.
What does the BC suffix indicate on the FA26015BC?
The BC suffix indicates that this 2-pole breaker is factory-configured to connect to the B and C phases of the I-Line busbar. This is critical for proper load balancing in your panel.
What wire sizes and materials are accepted by the lugs on this breaker?
The load-side lugs on the FA26015BC accept 14 AWG to 4 AWG wire and are rated for both copper and aluminum conductors.
What type of trip unit does the FA26015BC use?
It uses a fixed thermal-magnetic trip unit with long-time and instantaneous trip functions to protect against overloads and short circuits.
What safety precautions should be taken before installing this I-Line breaker?
Always ensure the panelboard is fully de-energized before installation. Verify that the B-C phase configuration matches your load balancing requirements and that the breaker is properly seated on the I-Line bus to prevent arcing.

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.
