Description
Designed to isolate electrical loads, the EHB3100N operates without thermal trip functions, serving purely as a disconnect. This 3-pole, 100A molded case switch is built for industrial applications requiring reliable manual switching. It mounts into Westinghouse NEHB panelboards to replace aging disconnects. Designed as a drop-in solution for legacy systems, it seamlessly replaces the EHD3100K. Rated at 480Y/277VAC, this bolt-on switch utilizes a fixed magnetic-only trip mechanism.Specifications

- 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!
