Product FAQs
6 answersAre Westinghouse EHB2100 and Cutler-Hammer EHB2100 breakers the same?
Yes. Eaton acquired the Westinghouse distribution equipment business and later transitioned the Cutler-Hammer brand. Westinghouse, Cutler-Hammer, and Eaton EHB2100 breakers are physically and electrically interchangeable.
Is the EHB2100 circuit breaker obsolete, and what is the modern replacement?
Yes, the legacy E-Frame EHB series is obsolete. The modern, direct drop-in replacement for the EHB2100 is the Eaton EHD2100, which shares the exact same form, fit, and function.
What panelboards are compatible with the EHB2100?
The EHB2100 is a bolt-on breaker designed for use in legacy Westinghouse F-Frame and NEHB panelboards, as well as Eaton Pow-R-Line C panelboards.
What wire sizes do the lugs on the EHB2100 accept?
The load side lugs on the EHB2100 accept aluminum or copper wire ranging from 4 AWG up to 2/0 AWG.
Does the EHB2100 have an adjustable trip setting?
No, the EHB2100 features a non-interchangeable, fixed thermal magnetic trip unit with factory-set long-time and instantaneous trip functions.
Can the EHB2100 be mounted on a standard DIN rail?
No. The EHB2100 is a bolt-on molded case circuit breaker designed specifically to bolt directly to the busbar of compatible Eaton and Westinghouse panelboards. It does not support DIN rail mounting.

- MSMike S.Verified BuyerReviewingSquare D EHB34060 - 60A 3 Pole Molded Case Circuit BreakerI recommend this productRated 5 out of 5 stars11/21/25Fast reliable service, reasonable prices
I recently ordered the incorrect breakers for a job, but I contacted Drew at SuperBreakers and he got me the correct breakers shipped out that day, which I received the next day. He sent me a label to send the wrong breakers back, and I was quickly refunded a restocking fee that I incurred for my mistake. I was able to get the breakers installed, and the power running to meet the deadline. Not to mention, the price was better than I found elsewhere. Thanks Drew!
I would definitely recommend this company if you need fast, reliable service for your electrical product needs. And I'm sure I will use them again.
Thank you SuperBreakers! Nice job Drew!
