Description
Designed to safeguard industrial facilities, the Eaton EHB2070 is a robust 70-amp molded case circuit breaker. It is built to protect commercial electrical systems against overloads and short circuits. Featuring a secure bolt-on mounting style, it integrates into classic Westinghouse and Eaton Pow-R-Line 4B panelboards. It acts as a vital maintenance component for older systems, serving as the predecessor to the modern EHD2070 replacement.Specifications

Product FAQs
5 answersWhich panelboards accept the EHB2070 circuit breaker?
This legacy E-Frame breaker is specifically designed to bolt into Eaton Pow-R-Line 4B distribution panelboards, as well as older Westinghouse panelboards that utilize the same chassis design.
What is the active replacement for the obsolete EHB2070?
Because the EHB series is a legacy product, Eaton offers the EHD2070 from the Series C F-Frame family as the modern, functional cross-reference for 70-amp, 2-pole applications.
How does the thermal-magnetic trip unit operate on this breaker?
The EHB2070 uses a fixed thermal and fixed magnetic mechanism. The thermal component provides long-time delayed protection against sustained overloads, while the magnetic component delivers instantaneous tripping during severe short circuits.
Are the load lugs included with the EHB2070?
Yes, the breaker comes equipped with standard pressure load terminals that accept wire gauges from 4 AWG up to 2/0 AWG for your branch circuit connections.
Is the Eaton EHB2070 interchangeable with Cutler-Hammer and Westinghouse versions?
Yes. Eaton acquired the Cutler-Hammer and Westinghouse electrical distribution lines, so this breaker serves as a direct replacement for older EHB2070 models branded under either of those names.

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!
