Product FAQs
6 answersWhat types of enclosures and panels are compatible with the HJD3070?
The HJD3070 is designed for use in Eaton and Cutler-Hammer Series C panelboards, switchboards, and motor control centers.
What are the standard terminal lugs for the HJD3070, and what wire sizes do they accept?
This J-frame breaker typically uses TA250KB standard lugs, which accept 4 AWG to 350 kcmil copper or aluminum wire.
What is the difference between the HJD3070 and the standard JD3070?
The H in HJD indicates a High Interrupting Capacity. The HJD3070 is rated for 65kAIC at 480VAC, whereas the standard JD3070 is rated for 35kAIC at 480VAC.
How does the adjustable magnetic trip function work on the HJD3070?
The magnetic trip dial allows you to adjust the instantaneous short-circuit response from 5 to 10 times the continuous current rating. For this 70A breaker, the magnetic trip can be set between 350A and 700A.
Is the HJD3070 suitable for reverse feed applications?
Yes, standard Eaton Series C thermal-magnetic breakers with non-interchangeable trip units, like the HJD3070, are HACR rated and suitable for reverse feed setups.
Can the Eaton HJD3070 replace an older Westinghouse HJD3070?
Yes. Eaton acquired the Westinghouse distribution equipment division, making the Eaton or Cutler-Hammer Series C HJD3070 a direct replacement for legacy Westinghouse models with the same catalog number.
