Part of the legacy Westinghouse and Cutler-Hammer E-Frame family, this 20-amp unit mount breaker provides reliable thermal-magnetic protection for commercial and industrial facilities. It features a non-interchangeable trip unit with fixed long-time and instantaneous functions. Designed for cable-in/cable-out applications, the device includes factory-installed line and load lugs. While this specific model is discontinued, modern upgrades typically use the EHD3020L substitute.
The original Westinghouse EHB3020L is a legacy E-Frame breaker and is no longer manufactured. For modern upgrades, the Eaton EHD3020L is typically used as a direct substitute for 480VAC unit-mount applications.
What does the L suffix indicate on the EHB3020L catalog number?
The L suffix designates that this breaker is a unit-mount model equipped with factory-installed lugs on both the line and load sides. It is designed for cable-in/cable-out applications and individual enclosures rather than bolting directly to a panelboard bus.
Can this breaker be installed in Eaton Pow-R-Line panelboards?
No. Because the EHB3020L features line-side lugs for feed-thru wiring, it cannot be bolted onto a standard panelboard bus. You would need the standard EHB3020 without the L suffix for Pow-R-Line or legacy Westinghouse panelboard installations.
Can the EHB3020L be used in DC applications?
Yes, this breaker is rated for use in DC systems up to 250VDC, providing a 10kA interrupting capacity for compatible direct current applications.
What wire sizes are accepted by the terminals on this breaker?
The line and load lugs are designed to accept 14 AWG to 10 AWG copper or aluminum conductors. Ensure proper torque specifications are followed during installation for secure connections.

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!
