Product FAQs

4 answers
Is the EHD3070 circuit breaker HACR rated?

Yes, like all Eaton Series C F-frame circuit breakers, the EHD3070 is fully HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment.

Can the EHD3070 be reverse fed?

Yes, this breaker features a non-interchangeable thermal magnetic trip unit that is fully approved for reverse feed installations.

Will this Eaton breaker replace an older Westinghouse EHD3070?

Yes. Eaton acquired the legacy Westinghouse and Cutler-Hammer distribution equipment lines. The current Eaton EHD3070 serves as the exact physical and electrical replacement for the older Westinghouse and Cutler-Hammer models sharing the same catalog number.

What conductor materials are supported by the standard EHD3070 terminals?

The standard factory lugs on this 70-amp breaker are dual-rated for both copper and aluminum wire. They are designed to accommodate conductor sizes ranging from 14 AWG to 1/0 AWG.
