Product FAQs
8 answersWhat does the "AB" suffix mean on the FA24035AB?
The "AB" suffix indicates the specific phase connection for the I-Line plug-on jaws. This 2-pole breaker is configured to connect to the A and B phases of an I-Line panelboard or switchboard bus.
Which panelboards accept the FA24035AB circuit breaker?
This F-frame breaker is designed exclusively for Square D I-Line panelboards and switchboards. It uses a plug-on jaw mechanism that engages directly with the I-Line bus assembly.
How does the FA24035AB mount into the panel?
It features an I-Line style plug-on connection on the line side. The breaker jaws push directly onto the panelboard bus stack, while the load side uses standard mechanical lugs for wire termination. A mounting bracket and screw secure the breaker to the panel backpan.
Can the FA24035AB be used in DC applications?
Yes, this thermal-magnetic breaker is rated for up to 250VDC with an interrupting capacity of 10kAIC. It is suitable for both AC and DC distribution systems within its voltage limits.
What wire sizes are compatible with the load lugs on the FA24035AB?
The factory-installed load lugs accept 14 to 1/0 AWG copper wire or 12 to 1/0 AWG aluminum wire. Ensure proper torque specifications are followed during installation to maintain a secure connection.
Is the FA24035AB still manufactured, or has it been replaced?
The FA frame is a legacy molded case circuit breaker from Square D. While still widely used and available as a direct replacement for existing F-frame I-Line slots, modern panel upgrades often utilize the PowerPacT B-frame series as a functional equivalent for new installations.
What type of trip unit is installed in the FA24035AB?
This breaker features a fixed thermal-magnetic trip unit. It provides both long-time overload protection (thermal) and instantaneous short-circuit protection (magnetic), designated by the LI trip function code.
Does the FA24035AB include a push-to-trip button for testing?
Yes, this molded case circuit breaker features a push-to-trip button on the front face. This allows users to manually trip the breaker to verify the mechanical operation of the trip mechanism without exposure to live parts.

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!
