Product FAQs
7 answersWhat enclosures and panels are compatible with the EHD2100?
This F-frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers. It is not compatible with standard residential load centers.
What is the difference between the EHD2100 and the FD2100?
Both are 100A, 2-pole F-frame breakers with the exact same physical dimensions. However, the FD2100 has a higher interrupting rating (35kA at 480VAC) and a higher maximum voltage rating (600VAC) compared to the EHD2100 (14kA at 480VAC).
Is the EHD2100 suitable for reverse feed applications?
Yes, Eaton F-frame circuit breakers, including the EHD2100, are suitable for reverse feed use. They can be backfed safely in applications that require it.
What does the LI trip function code mean on the EHD2100?
The LI designation indicates that the thermal-magnetic trip unit provides both Long-Time (thermal overload) and Instantaneous (magnetic short circuit) protection. Both of these trip settings are fixed and non-interchangeable on this specific frame.
Can the EHD2100 be used in DC voltage applications?
Yes, it is rated for up to 250VDC with a 10kA interrupting capacity. This makes it suitable for industrial DC control circuits and systems requiring reliable DC branch circuit protection.
Is the EHD2100 HACR rated?
Yes, all Eaton F-frame circuit breakers are HACR rated, meaning this breaker is approved for use with heating, air conditioning, and refrigeration equipment.
What wire sizes and materials are accepted by the standard lugs on this breaker?
The standard terminals accommodate either copper or aluminum conductors ranging from 14 AWG to 1/0 AWG.
