Description
Designed to support existing industrial infrastructure, this 30A thermal-magnetic breaker delivers proven LI protection. It helps facility managers maintain older electrical distribution networks without extensive retrofits. Installation is straightforward into classic Westinghouse motor control centers and switchboards. When transitioning to newer components, the FD3030 is the recommended replacement path. With an 18kAIC rating at 240V and AB De-Ion arc quenching, it mitigates fault currents.Specifications

Product FAQs
4 answersWhat panelboards are compatible with the FA3030 circuit breaker?
The FA3030 is designed to fit legacy Westinghouse panelboards, motor control centers, and switchboards. It is also compatible with Eaton Pow-R-Line C panelboards, as Eaton maintained backward compatibility with the original Westinghouse F-frame footprint.
Is the Westinghouse FA3030 an obsolete circuit breaker?
The FA frame is a legacy Westinghouse design. While Eaton, which acquired the Westinghouse distribution equipment division, continues to support these profiles, the Series C FD3030 is often the recommended replacement path when upgrading to newer components.
Can the FA3030 be used in direct current applications?
Yes, this breaker is rated for up to 250VDC with an interrupting capacity of 10kA, making it suitable for specific direct current systems.
Does the FA3030 feature adjustable trip settings?
No, the FA3030 features a fixed thermal and fixed magnetic trip unit. It provides standard long-time and instantaneous (LI) protection without user-adjustable dials.

- 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.
