Product FAQs
6 answersWhat enclosures or panelboards accept the EHD3070L?
It is designed for use in Eaton Series C panelboards, switchboards, and motor control centers that accept F-frame breakers.
Can the Eaton EHD3070L replace older Westinghouse EHD breakers?
Yes, Eaton acquired the Westinghouse distribution equipment line. The Series C EHD3070L is a direct replacement for legacy Westinghouse and Cutler-Hammer EHD3070L breakers.
What does the L suffix in the EHD3070L catalog number indicate?
The L suffix indicates that the breaker is supplied with standard pressure line and load terminals (lugs) installed from the factory.
Is the EHD3070L suitable for reverse feed applications?
Yes, this thermal-magnetic F-frame breaker is suitable for reverse feed applications.
Does the EHD3070L provide adjustable trip settings?
No, it features a fixed thermal and fixed magnetic trip unit, meaning both the overload and short-circuit trip points are factory set and non-adjustable.
How is the EHD3070L mounted in a panel?
This is a unit mount (bolt-on) breaker. It must be bolted directly to the panel bus or mounting pan, rather than snapping into place like a plug-on breaker.
