Eaton EHD3070 – Frequently Asked Questions
1) Will the Eaton EHD3070 breaker work on a 480V three-phase panel?
Yes, the EHD3070 is rated for 480 Vac service, but the interrupting capacity drops at that voltage: 14 kAIC at 480 Vac versus 18 kAIC at 240 Vac. Compare the 14 kAIC figure against the available fault current at your panel before you commit. It is a three-pole breaker rated 70A and will run on either 50 or 60 Hz systems.
2) Is the EHD3070 a complete breaker or just a trip unit I have to build up?
It ships as a complete breaker. The EHD3070 is an F-frame unit in Eaton's Series C line with the trip already built in, so there is no separate trip unit, rating plug, or frame to order alongside it. Load side terminals are included.
3) Can the trip setting on an EHD3070 be adjusted in the field?
No. The EHD3070 uses a fixed thermal, fixed magnetic trip, so both the overload and the instantaneous pickup are factory set at the 70A rating. If your application needs an adjustable instantaneous or an electronic trip with settable long-time and short-time curves, this is the wrong breaker type and you want an adjustable-trip F-frame instead.
4) What size space do I need in the panel or enclosure for an EHD3070?
Plan for a breaker measuring 6 x 4.13 x 3.38 inches (height x width x length) and weighing 4.5 lb. That footprint is the F-frame case size, so it drops into gear prepped for an EHD F-frame three-pole without rework.
5) Does the EHD3070 come with lugs for the line side as well as the load side?
Terminals are specified on the load side. If your installation requires line side lug kits or any accessory such as a shunt trip, auxiliary switch, or handle mechanism, those are ordered separately from the breaker itself.
6) Where can I get the full spec sheet for the Eaton EHD3070?
Eaton publishes a dedicated spec sheet for the EHD3070, and it is linked directly from the product information. That document is the place to check trip curves and accessory part numbers for the F-frame Series C breaker.
