B-LINE EHD3070 – Frequently Asked Questions
1) What is the interrupting rating on the Eaton EHD3070 breaker at 240V and 480V?
The EHD3070 is rated 18 kAIC at 240 Vac and 14 kAIC at 480 Vac. Match that against the available fault current at your panel location; if your short circuit study calls for more than 18 kAIC on a 240V system, this EHD frame will not satisfy the spec.
2) Is the EHD3070 a three-pole 70 amp breaker?
Yes, three poles at 70 amps, so it lands on a three-phase feeder or branch circuit. It is an EHD type breaker in Eaton's Series C F-frame line.
3) Is the EHD3070 adjustable, or is the trip setting fixed?
Fixed on both ends: fixed thermal and fixed magnetic trip. There is no adjustable magnetic dial, so the 70 amp rating is what you get. If the application needs an adjustable instantaneous setting for motor inrush, this is not the breaker for it.
4) I need to replace an existing EHD three-pole breaker in an Eaton panel. What do I confirm before ordering the EHD3070?
Three things decide it: the pole count (this is three-pole), the amp rating (70A), and the interrupting rating your panel schedule requires (this one gives 18 kAIC at 240 Vac and 14 kAIC at 480 Vac). EHD is the type designation and F-frame is the frame size, so an existing EHD F-frame position in a Series C panel is the same family. Read the label on the old breaker and match the EHD prefix plus the 3070 suffix exactly.
5) Is the EHD3070 a complete breaker or just a trip unit?
It ships as a complete molded case breaker, not an interchangeable trip unit or a frame that needs one added. Nothing separate has to be ordered to make it functional.
6) How much space do I need in the enclosure for the EHD3070, and what does it weigh?
Plan for a unit measuring 6 x 4.13 x 3.38 inches (height x width x length as published) weighing 4.5 lb. That footprint and weight matter when you are checking gutter space in a retrofit panel or figuring a bracket mount.
7) Does the EHD3070 come with lugs?
Terminals are load side on this breaker. Verify what your line side connection needs to be before you order any additional terminal hardware.
8) Will the EHD3070 work on a 50 Hz system?
Yes. The breaker is rated 50/60 Hz, so it works on either standard power frequency.
