Product FAQs
6 answersIs there a modern direct replacement for the legacy FA36030?
Yes. Schneider Electric has superseded the legacy F-frame breakers with the PowerPact B-frame series. The factory recommended exact modern replacement is the PowerPact BDA36030, which maintains the 30A, 3-pole rating and the I-Line plug-on connection.
Can I use the FA36030 to replace an FAL36030?
No. While both are 30A, 3-pole F-frame circuit breakers with identical electrical capabilities, their mounting designs differ. The FA36030 requires an I-Line panelboard bus for its plug-on line side connection. The FAL36030 is a unit-mount version designed for panel-mount or standalone enclosure applications using line and load lugs.
How does the I-Line mounting system attach the FA36030 to the bus?
The breaker uses integral plug-on jaws on the line side that snap directly onto the vertical bus bars of an I-Line panelboard or switchboard. This connection uses a specialized blow-on joint design where the magnetic forces generated during a short circuit actually pull the jaws tighter to the bus, increasing connection integrity during a fault.
Is the FA36030 suitable for use in standalone individual enclosures?
No. Because it is an I-Line plug-on breaker, the FA36030 must be installed in an I-Line panelboard or switchboard with the correct bus architecture. If you require a breaker for a standalone NEMA enclosure, you will need a unit-mount equivalent like the FAL36030 paired with a compatible FA100 series enclosure.
Can the FA36030 be reverse-fed to act as a main breaker?
Yes, thermal-magnetic breakers without explicit Line and Load markings can typically be backfed. In an I-Line panelboard, a branch breaker like the FA36030 can be used as a backfed main to energize the interior bus. However, when used as a service entrance main, the National Electrical Code (NEC) requires the backfed device to be fastened with a properly rated fastener and clearly labeled as the main breaker.
What type of overcurrent protection does the FA36030 provide?
The FA36030 uses a fixed thermal-magnetic trip unit to provide standard LI (Long-Time and Instantaneous) protection. The thermal bimetal element responds to prolonged overloads by heating and tripping the mechanism, while the magnetic electromagnet provides instantaneous tripping when a severe short circuit is detected.

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.
