Product FAQs
5 answersWhich panelboards are compatible with the EHB2050 circuit breaker?
The EHB2050 is designed for bolt-on installation in legacy Westinghouse panelboards and Eaton Pow-R-Line 4B distribution panels.
What is the direct replacement for the obsolete EHB2050?
The EHB series is a legacy E-frame breaker that is no longer manufactured. It has been superseded by the Eaton EHD2050, an F-frame breaker that serves as an exact physical and functional replacement for aging infrastructure.
Is the Eaton EHB2050 HACR rated?
Yes, this breaker is HACR rated, making it fully compliant for protecting heating, air conditioning, and refrigeration equipment circuits.
Are the trip settings on the EHB2050 adjustable?
No, the EHB2050 is equipped with a non-interchangeable, fixed thermal-magnetic trip unit. Both the long-time (overload) and instantaneous (short-circuit) trip functions are factory-set and cannot be adjusted in the field.
How is the EHB2050 installed into the panelboard?
The EHB2050 features a bolt-on connection type. It must be mechanically bolted directly to the panelboard bus, which provides a secure, high-vibration-resistant connection compared to plug-on alternatives.

- 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!
