Description
Serving commercial facilities, this 20-amp Eaton EHB1020 molded case circuit breaker offers dependable thermal-magnetic trip functions. It operates at 277VAC with a 14kAIC rating, ensuring safe branch circuit protection. The breaker bolts into Eaton Pow-R-Line C and legacy Westinghouse F-Frame panelboards. While this E-Frame unit is widely used for maintenance, the EHD1020 serves as its modern replacement. It includes SWD and HID ratings for switching standard and high-intensity lighting.Specifications

Product FAQs
6 answersWhat is the direct replacement for the obsolete EHB1020?
The EHB1020 is a legacy E-Frame breaker that has been discontinued by Eaton. It is directly replaced by the F-Frame EHD1020, which maintains the same form, fit, and function for existing electrical systems.
Will the EHB1020 fit in older Westinghouse panelboards?
Yes, this legacy breaker is designed to bolt directly into older Westinghouse F-Frame panelboards, as well as Eaton Pow-R-Line C panelboards, without requiring special mounting adapters.
Is the EHB1020 suitable for DC circuits?
Yes, in addition to its standard AC ratings, this breaker is rated for 125VDC applications. It provides up to 10kAIC of interrupting capacity for direct current systems.
What wire types and sizes are compatible with the EHB1020 lugs?
The standard load-side lugs accept 14 AWG to 10 AWG copper or aluminum wire. Ensure conductors are properly sized for 20-amp branch circuits according to local electrical codes.
Can the trip settings on the EHB1020 be adjusted?
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 cannot be modified in the field.
Does the EHB1020 provide branch circuit protection?
Yes, it is a UL 489 listed molded case circuit breaker designed for primary branch circuit protection. It also complies with CSA and NEMA AB 1 standards for commercial and industrial use.

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!
