Product FAQs
6 answersWhich panelboards accept the EHB1030 circuit breaker?
This legacy E-Frame breaker is specifically designed to bolt into older Westinghouse NEHB panelboards. It provides an exact fit for aging infrastructure without the need for mounting adapters.
Are Westinghouse, Cutler-Hammer, and Eaton EHB1030 breakers interchangeable?
Yes. Eaton acquired both Cutler-Hammer and the Westinghouse electrical distribution lines. EHB series breakers may be labeled under any of these three brands, but they share the exact same fit, form, and function for NEHB panelboards.
Is the Westinghouse EHB1030 an obsolete breaker?
Yes, the EHB series is a legacy product line. While the original E-Frame is obsolete, exact-fit replacements are available to maintain existing NEHB panels. For complete panel upgrades, Eaton replaced this series with the F-Frame EHD1030.
What type of wire can be used with the EHB1030 lugs?
The terminals on this breaker are rated for both copper (Cu) and aluminum (Al) conductors, accepting wire sizes from 14 AWG to 10 AWG.
Is the EHB1030 suitable for direct current (DC) circuits?
Yes, in addition to its standard AC ratings, this breaker is certified for use in DC electrical systems up to 125VDC with a 10kA interrupting capacity.
Can I adjust the trip settings on the EHB1030?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time overload and instantaneous short-circuit trip functions are factory-set and non-adjustable.

- 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!
