Description
Engineered for commercial and industrial applications, the EB2020 delivers reliable thermal-magnetic protection. It serves as a crucial component for maintaining older infrastructure. This unit mounts into classic Westinghouse and Eaton panelboards. It provides an exact fit for systems specifying E-frame breakers, acting as a predecessor to the EHD2020 substitute. Featuring a 10kAIC rating at 240VAC, it utilizes proven AB De-Ion arc extinction technology to clear faults safely.Specifications

Product FAQs
6 answersIs the Eaton / Westinghouse EB2020 still in active production?
The EB2020 is a legacy E-frame circuit breaker that is no longer manufactured. For modern upgrades or replacements, the Eaton EHD2020 serves as the exact mechanical and electrical substitute.
Which panelboards accept the EB2020 circuit breaker?
This bolt-on breaker is designed to mount into classic Westinghouse, Cutler-Hammer, and Eaton panelboards that specify legacy E-frame components.
What is the difference between the EB2020 and the EHB2020?
Both are 20A, 2-pole E-frame breakers, but they have different voltage and interrupting ratings. The EB2020 is rated for 240VAC at 10kAIC, while the EHB2020 is rated for 480Y/277VAC at 14kAIC.
Is the EB2020 circuit breaker HACR rated?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires this specific protection standard.
Can the EB2020 be applied to DC circuits?
Yes, in addition to its 240VAC rating, the EB2020 is rated for 125/250VDC applications with a 5kAIC interrupting capacity. This makes it suitable for substantially non-inductive DC circuits.
What type of connections are used on the EB2020?
The EB2020 is a bolt-on breaker that fastens directly to the panelboard bus. On the load side, it comes equipped with standard lugs that accept 14-10 AWG aluminum or copper conductors.
