Product FAQs
6 answersWhat panelboards are compatible with the EHB1025 circuit breaker?
The EHB1025 is a bolt-on breaker designed for use in legacy Westinghouse panelboards that accept E-Frame breakers.
Is the EHB1025 obsolete, and what is the modern replacement?
Yes, the EHB series is a legacy product that has been discontinued by Eaton. It has been replaced by modern Eaton F-Frame circuit breakers, such as the EHD series, which serve as direct substitutes for legacy Westinghouse panelboards.
Can the EHB1025 be used in DC electrical systems?
Yes, this thermal-magnetic breaker is rated for use in DC applications up to 125VDC, where it provides a 10kA interrupting capacity.
Does the EHB1025 require a retrofit kit to install in older Westinghouse panels?
No, the EHB1025 is an exact fit for legacy Westinghouse panelboards designed for E-Frame bolt-on breakers, eliminating the need for retrofit kits or mounting adapters.
Are Eaton and Westinghouse EHB breakers the same?
Yes. Eaton acquired Westinghouse's distribution equipment division, so EHB breakers manufactured under the Eaton, Cutler-Hammer, or Westinghouse brands are physically and functionally identical.
Are the trip settings adjustable on the EHB1025?
No, the EHB1025 features a non-interchangeable trip unit with fixed thermal and fixed magnetic settings for long-time and instantaneous overcurrent protection.

- 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!
