Product FAQs
5 answersDoes the KA3225F include the trip unit and terminal lugs?
No, the KA3225F is a circuit breaker frame only. The thermal-magnetic trip unit and terminal lugs are not included and must be sourced and installed separately to complete the breaker assembly.
What are the interrupting capacity (AIC) ratings for this KA-frame breaker?
When fully assembled, this frame is rated for 25 kAIC at 240V AC, 22 kAIC at 480V AC, and 22 kAIC at 600V AC. It also carries a 10 kAIC rating at 250V DC.
Which panelboards are compatible with the KA3225F frame?
This bolt-on frame is designed for installation in legacy Westinghouse and Eaton/Cutler-Hammer Pow-R-Line C panelboards, CDP enclosures, switchboards, and motor control centers.
Can this frame be used to replace older Westinghouse KA breakers?
Yes. The KA3225F was originally manufactured by Westinghouse and later transitioned to the Eaton/Cutler-Hammer brand. It serves as an exact physical and electrical replacement for older Westinghouse KA-frame breakers.
What is the modern replacement for the obsolete KA3225F?
For modern panel upgrades, the legacy KA3225F is typically replaced by the newer KD3225 circuit breaker. Upgrading to the KD-frame requires a TAD3 adapter spacer to fit the existing mounting footprint.

I have purchased multiple breakers (of fairly large size) from SuperBreakers and their pricing has been excellent and the delivery time spot on. I would highly recommend them

I have ordered many breakers through SuperBreakers with no issues until this order. I ordered this breaker and it wasn't shipped. I sent a message and was told that a mistake was make in shipping and that they would next day air the breaker to me. 5 days later (weekend in there) the breaker arrived. Not next day air, but shit happens. Sent the breaker still in the box out with my electrician and received a call from him that the breaker that was sent was a KAL36100 not the KA36100. I reached out to SuperBreakers and was told the correct breaker would be next day aired that day and I was emailed a shipping label to send back the incorrect one. This time it arrived the next day and was installed. This error cost my customer a couple days with out power to a dimmer cabinet and about 2 extra hours of labor, but all was okay in the end. Mistakes happen. The help and quick responses to my emails I received from Mike David showed me enough about this company. I look forward to my next order. Thank you for working this situation out in timely manor.

They had what we needed to match existing equipment, they shipped the same day and we put it right into service, no problems from first phone call to delivery and install.
