Product FAQs
7 answersWhat does the -2100 suffix indicate on the FA36015-2100 circuit breaker?
The -2100 suffix indicates that this breaker includes a factory-installed normally open bell alarm switch. This auxiliary contact provides remote signaling when the breaker trips due to an overcurrent or short circuit.
What type of panelboards will accept the FA36015-2100 breaker?
This FA-frame breaker features an I-Line style plug-in connection on the line side. It is designed exclusively for use in Square D I-Line panelboards and switchboards.
Can the FA36015-2100 be used as a unit-mount or lug-in/lug-out breaker?
No. The FA prefix designates an I-Line plug-in connection on the line side. For a standard unit-mount configuration with lugs on both the line and load sides, you would need the FAL36015 equivalent, or FAL36015-2100 if the alarm switch is still required.
Will the FA36015-2100 fit in a Square D QO or NQ load center?
No. This is an F-frame molded case circuit breaker with an I-Line plug-in connection. It will not fit in QO, NQ, or NF series panelboards, which require different breaker frame types.
What protection does the LI trip function provide on the FA36015-2100?
The LI designation means the thermal-magnetic trip unit provides Long-Time (L) protection against sustained overloads and Instantaneous (I) protection against severe short circuits. Both trip settings are fixed on this specific 15A model.
What are the magnetic hold and trip current settings for this 15A breaker?
The FA36015-2100 has a fixed magnetic hold current of 275A and a magnetic tripping current of 600A.
Is the FA36015-2100 suitable for HVAC applications?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires this specific certification.

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!
