Description
Built for heavy-duty power distribution, this 35-amp molded case circuit breaker secures commercial electrical systems against overloads and short circuits. The bolt-on design fits seamlessly into Eaton Pow-R-Line C and classic Westinghouse F-Frame panelboards. With an interrupting capacity of 65kA at 240VAC and 14kA at 480Y/277VAC, it meets stringent safety standards including UL 489. Facilities upgrading their infrastructure often transition to the EHD3035 substitute.Specifications

Product FAQs
7 answersWhich panelboards accept the EHB3035 circuit breaker?
This F-Frame breaker is designed for bolt-on installation in modern Eaton Pow-R-Line C panelboards as well as legacy Westinghouse and Cutler-Hammer F-Frame distribution panels.
What is the modern replacement for the EHB3035?
The EHB series is a legacy F-Frame breaker. If you are upgrading your infrastructure, the Eaton EHD3035 is the direct substitute, offering the same physical dimensions and 14kA at 480VAC interrupting capacity.
Does the EHB3035 require a specific mounting kit?
Yes, as a bolt-on F-Frame breaker, it requires the appropriate twin or single mounting hardware kit to secure it to the busbar in Pow-R-Line or legacy Westinghouse switchboards.
What type of protection does the EHB3035 trip unit provide?
It features a fixed thermal-magnetic trip unit with long-time and instantaneous (LI) functions. The thermal element responds to prolonged overloads, while the magnetic element trips immediately during short circuits.
Can the EHB3035 be used in high-vibration environments?
Yes, the bolt-on connection provides a secure mechanical attachment to the panelboard bus. This ensures a reliable connection that resists loosening in industrial or high-vibration environments, reducing the risk of arcing.
Is the EHB3035 rated for direct current (DC) systems?
Yes, alongside its standard AC ratings, this breaker is certified for 250VDC applications with a 10kA interrupting capacity, making it suitable for industrial DC control and distribution circuits.
What wire sizes are compatible with the EHB3035 terminals?
The factory lugs on this 35-amp breaker accept wire sizes from 14 AWG to 2 AWG. Always torque the terminal screws to the manufacturer specifications printed on the breaker to ensure a safe connection.

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!
