Product FAQs
7 answersWhat panelboards are compatible with the EHB3015 circuit breaker?
This bolt-on breaker is designed specifically for use in legacy Westinghouse NEHB panelboards. It mounts directly to the panel bus and is not compatible with standard plug-on load centers.
What is the modern replacement for the obsolete EHB3015?
The original Westinghouse EHB series is obsolete. The Eaton EHD3015 serves as the modern equivalent and direct replacement for maintaining existing NEHB panelboards.
Can the EHB3015 be used in DC electrical systems?
Yes, in addition to its AC ratings, this breaker is certified for DC applications up to 250VDC, providing a 10kA interrupting capacity for direct current circuits.
What does the LI trip function code indicate on this breaker?
The LI designation stands for Long-Time and Instantaneous trip functions. This provides standard thermal-magnetic protection, utilizing a bimetallic strip for sustained overloads and a magnetic coil for immediate short-circuit clearing.
Are the trip settings on the EHB3015 adjustable?
No, this breaker features fixed thermal and fixed magnetic trip elements. The trip unit is non-interchangeable and cannot be modified in the field.
Does the EHB3015 include line and load side lugs?
This breaker includes load side lug terminals that accept 14 to 10 AWG copper or aluminum wire. The line side features a bolt-on connection designed to mount directly to the panelboard bus.
What safety precautions are required when removing an EHB breaker from an NEHB panel?
Always ensure the main power to the panelboard is completely de-energized and verified with a reliable voltage tester before unbolting the breaker from the live bus.

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!
