This bolt-on unit serves as an exact drop-in replacement for older Westinghouse panelboards, switchboards, and motor control centers. It is the direct predecessor to the modern FD3015. Rated for 14 kAIC at 480VAC, it includes proven AB De-Ion arc quenching.Specifications

Product FAQs
6 answersWhat panelboards and equipment are compatible with the FA3015?
The FA3015 is designed for use in legacy Westinghouse panelboards, motor control centers, and switchboards. It is also compatible with Eaton Pow-R-Line C panelboards.
Is the Westinghouse FA3015 interchangeable with Eaton or Cutler-Hammer breakers?
Yes. Eaton acquired the Westinghouse distribution equipment division, meaning FA3015 breakers branded as Eaton, Cutler-Hammer, or Westinghouse are physically and electrically interchangeable.
What is the modern replacement for the legacy FA3015 circuit breaker?
The direct modern replacement for the legacy FA3015 is the Eaton FD3015. It shares the exact same F-Frame footprint, allowing for straightforward maintenance and retrofitting in existing enclosures.
Can the FA3015 be used in DC electrical systems?
Yes. While primarily installed in AC systems up to 600VAC, the FA3015 is also rated for DC applications up to 250VDC with an interrupting capacity of 10kA.
What wire sizes are accepted by the lugs on the FA3015?
The standard bolt-on lugs for the FA3015 accept wire gauges from 14 AWG up to 1/0 AWG. The terminals are rated for both copper (Cu) and aluminum (Al) conductors.
What type of trip unit does the FA3015 use?
It features a fixed thermal magnetic trip unit that provides standard long-time and instantaneous (LI) protection against overloads and short circuits. Both the thermal and magnetic trip points are fixed and cannot be adjusted in the field.

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!
