Product FAQs
6 answersWhat panelboards are compatible with the FA3601535 circuit breaker?
This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It features a specialized plug-on connection that mounts directly to the I-Line bus, making it incompatible with standard load centers or unit-mount applications.
Can the FA3601535 be used in DC power systems?
Yes, in addition to its AC ratings, this thermal-magnetic breaker is rated for use in DC applications up to 250VDC with an interrupting capacity of 10kAIC. This makes it suitable for specific industrial control or battery-backed systems.
What wire sizes are accepted by the load-side lugs on this breaker?
The factory-installed mechanical lugs on the FA3601535 accept 14 AWG to 4 AWG copper (Cu) or aluminum (Al) conductors. Ensure proper torque specifications are followed during installation as outlined on the breaker faceplate.
What is the modern replacement for the legacy FA3601535?
The FA frame is a legacy Square D series. For modern upgrades or new installations, the PowerPact H-frame series, specifically catalog numbers like the HDA36015, serves as the current generation replacement for 15A, 3-pole I-Line applications.
How does the I-Line mounting style differ from standard unit-mount breakers?
I-Line breakers like the FA3601535 feature plug-in jaws on the line side that attach directly to the panelboard busbar. This allows for faster installation compared to unit-mount breakers, which require bolt-on cable or bus connections on both the line and load sides.
How can I tell if the FA3601535 has tripped?
When the breaker trips due to an overcurrent or short circuit, the operating handle moves to a central tripped position, halfway between ON and OFF. To reset the breaker, the handle must first be pushed completely to the OFF position before being moved back to ON.

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!
