Product FAQs
6 answersWhat does the -1121 suffix indicate on this catalog number?
The -1121 suffix signifies that the breaker includes a factory-installed 120VAC Undervoltage Release (UVR) accessory.
How does the Undervoltage Release (UVR) affect breaker operation?
The UVR coil must be continuously energized with 120VAC to allow the breaker to close. If the control voltage drops below a predetermined safe level, the UVR will automatically trip the breaker to protect the circuit.
Which panelboards are compatible with the FA36060-1121?
This plug-in molded case circuit breaker is designed exclusively for installation in Square D I-Line panelboards and switchboards.
What are the lug wire size requirements for this breaker?
The standard factory-installed lugs on this breaker accept conductor sizes from 14 AWG up to 1/0 AWG. They are dual-rated for use with either copper or aluminum wire.
Are the trip settings adjustable on the FA36060-1121?
No, this breaker features a thermal-magnetic trip unit with fixed long-time and fixed instantaneous trip functions. The trip points cannot be adjusted in the field.
Is this breaker suitable for DC voltage applications?
Yes, it is rated for use in DC electrical systems up to 250VDC, where it provides a maximum interrupting capacity of 10kA.

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.
- AHAnn H.Verified BuyerReviewingSquare D FA36100 - 100A 3 Pole Molded Case Circuit BreakerI recommend this productRated 5 out of 5 stars8/22/26Professional 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!

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.
