Built for commercial applications, this 90A molded case circuit breaker provides reliable thermal-magnetic protection. It is part of the legacy F-Frame series, delivering proven performance for power distribution. The unit installs into Square D I-Line panelboards and switchboards. While it serves as a replacement for older systems, it has been superseded by the HDA260903 model. Rated 18 kAIC at 480VAC, it features a BC phase connection and Visi-Trip indicator for quick fault identification.
Can I install this F-Frame breaker in a standard QO or NQ load center?
No, this F-Frame breaker features a specialized plug-on connection and is physically incompatible with standard QO, NQ, or NF series load centers. It is designed exclusively for use in Square D I-Line industrial panelboards and switchboards.
What does the BC suffix indicate on this circuit breaker?
The BC suffix means this two-pole breaker is factory-configured to connect to the B and C phases of the I-Line busbar. This specific phase arrangement helps electricians balance the electrical load across the panelboard.
Can I change the phase connection on this breaker in the field?
No, the phase connection on Square D I-Line breakers is permanently set at the factory. You must order the correct suffix, such as AB, BC, or AC, to match the specific phase configuration required for your installation.
Is the FA24090BC still being manufactured, or is there a newer replacement?
The FA series is a legacy F-Frame breaker. While exact replacements like the FA24090BC are still utilized to maintain existing systems, Square D has superseded this line with the modern PowerPact H-Frame series for new installations.
Does this breaker include a Visi-Trip indicator?
Yes, Square D FA series breakers feature the Visi-Trip indicator. When the breaker trips due to an overcurrent or short circuit, the handle snaps to a distinct mid-position, allowing you to quickly identify the faulted circuit in a crowded panel.
Can I add accessories like a shunt trip or auxiliary switch to this breaker?
Yes, this legacy F-Frame breaker supports several internal accessories, including shunt trips, auxiliary switches, and undervoltage releases. Ensure any accessory you select is specifically designed for Square D FA or F-Frame circuit breakers.
Is this breaker suitable for use with HVAC equipment?
Yes, the FA24090BC is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment that requires this specific level of protection.

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.
