Product FAQs
7 answersWhat panelboards are compatible with the FA34030-1212 circuit breaker?
This plug-in breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. The line side connects directly to the I-Line bus assembly.
What does the -1212 suffix indicate on this FA frame breaker?
The -1212 suffix means the breaker includes a factory-installed 1A/1B auxiliary switch (part number FA11212). This provides one normally open and one normally closed contact for remote status signaling.
What is the difference between the standard FA34030 and the FA34030-1212?
The base FA34030 is a standard 3-pole, 30A I-Line breaker. The FA34030-1212 is the exact same breaker but includes the factory-installed auxiliary switch for monitoring the open or closed status of the contacts.
How are the wire connections made on the FA34030-1212?
As an I-Line breaker, the line side plugs directly into the panelboard bus. The load side features mechanical lugs that accept 14 to 4 AWG copper or 12 to 4 AWG aluminum conductors.
Can the FA34030-1212 be used in DC power systems?
Yes, this thermal-magnetic breaker is rated for use in DC applications up to 250VDC, with an interrupting capacity of 10kA.
Does the FA34030-1212 include ground fault or arc fault protection?
No, this is a standard thermal-magnetic breaker equipped with fixed long-time and instantaneous trip functions. It provides overload and short-circuit protection but does not offer GFCI or AFCI capabilities.
Is the FA34030-1212 a current production model?
The FA frame is a legacy molded case circuit breaker series. While it is still widely used to service existing I-Line panelboards, Square D generally recommends the PowerPacT series for new construction.

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!
