Product FAQs
6 answersWhich panelboards accept the EHD2020 circuit breaker?
This F-frame breaker mounts into Eaton Series C panelboards, including Pow-R-Line 1a, 2a, 3a, and 4, as well as compatible switchboards and legacy AB De-Ion panels.
Is the Eaton EHD2020 a direct replacement for the Westinghouse EHD2020?
Yes. Eaton manufactures this breaker to the exact specifications of the legacy Westinghouse EHD2020. It shares the same F-frame footprint and bolt-on mounting, allowing for a direct swap without panel modifications.
Can the EHD2020 be installed in direct current (DC) systems?
Yes, in addition to standard AC ratings, this breaker is rated for use in 250VDC systems, making it suitable for industrial DC control panels and battery applications.
What does the LI trip function code mean on the EHD2020?
The LI designation indicates that the thermal-magnetic trip unit provides Long-Time (L) overload protection and Instantaneous (I) short-circuit protection.
Does the EHD2020 feature adjustable trip settings?
No, this is a standard thermal-magnetic breaker with fixed thermal (long-time) and fixed magnetic (instantaneous) trip elements. It does not support field adjustments for the trip curve.
Are lugs included with the EHD2020, and what wire materials are supported?
Yes, the breaker includes standard load-side lugs. They are dual-rated for both copper and aluminum conductors ranging from 14 AWG to 1/0 AWG.
