Description

Part of the classic E-Frame lineup, this 20A, 2-pole molded case circuit breaker is engineered for legacy commercial facilities. It mounts into Westinghouse and Cutler-Hammer NEHB panelboards, offering an exact mechanical and electrical match for discontinued hardware. Delivering 14 kAIC of interrupting capacity at 480Y/277VAC, it utilizes a non-interchangeable thermal-magnetic trip mechanism. For modern cross-reference, the EHD2020 serves as the exact substitute for this component.

    Fast 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!
