Product FAQs
6 answersWhat does the L suffix in the EHD3100L catalog number indicate?
The L suffix indicates that the circuit breaker is factory equipped with both line and load side lug terminals. Without this suffix, standard Eaton F-frame breakers typically only include load side terminals.
Which panelboards are compatible with this F-frame circuit breaker?
This unit mounts directly into Eaton Series C panelboards, switchboards, and motor control centers that are designed to accept F-frame molded case circuit breakers.
What wire sizes and materials are accepted by the standard lugs on this breaker?
The included line and load lugs accept 14 AWG to 1/0 AWG wire. They are dual rated for use with either copper or aluminum conductors.
Is the EHD3100L suitable for use in heating, air conditioning, and refrigeration applications?
Yes, all Eaton Series C F-frame circuit breakers are HACR rated for use in HVACR equipment branch circuits.
Can this circuit breaker be reverse fed?
Yes, Eaton F-frame circuit breakers are suitable for reverse feed applications, allowing you to wire the line connection to either the top or bottom terminals.
Can I swap out the trip unit on this model to change the amperage?
No, this breaker features a fixed thermal and fixed magnetic trip unit. The trip unit is non-interchangeable, so the entire breaker must be replaced if a different amperage is required.
