Eaton / Cutler-Hammer EGH3070FFG Molded Case Circuit Breaker

No. This is a unit-mount molded case circuit breaker designed for Eaton Series G industrial enclosures, OEM control panels, and switchboards. It does not plug or bolt into standard residential breaker boxes.

The first F indicates a fixed thermal trip, the second F indicates a fixed magnetic trip, and the G signifies that standard line and load side lug terminals are included with the breaker.

All of these belong to the Eaton Series G EG-frame family and share the same physical dimensions. The difference is the interrupting capacity. The EGH offers the highest rating in this group, providing 65kA at 480VAC, whereas EGB, EGE, and EGS offer lower fault current ratings.

It is a unit-mount breaker, meaning it is secured directly to a panel backplate or mounting surface using screws. It can also be mounted to a standard 35mm DIN rail if you use the compatible Eaton DIN rail adapter bracket.

Yes. The included line and load lugs can be removed to accommodate alternate termination hardware, such as nut keeper plates for ring terminals or multi-wire lug kits, depending on your application requirements.

Yes, this thermal-magnetic breaker is rated for use in DC systems up to 250VDC, where it provides a 42kA interrupting capacity. Ensure you follow Eaton wiring diagrams for proper pole connections in DC applications.

No. The EGH3070FFG features a standard thermal-magnetic trip unit that provides long-time (overload) and instantaneous (short-circuit) protection only. It does not include built-in ground fault or equipment protection features.

The factory-installed lugs accept wire gauges from 14 AWG up to 1/0 AWG. They are dual-rated for use with either copper or aluminum conductors. Always torque to the manufacturer specifications printed on the breaker.
