    Time Current Curves for Obsolete Fuses

    Would anyone know where to find datasheets and time current curves for old Federal Pacific Electric ECN fuses? My company is currently doing an arc flash study for an old building that has some of these fuses in disconnect switches and SKM doesn't have it in their library or their developmental library. There seems to be a lack of information on FPE on the internet. I've been able to find data sheets and tcc's on FPE circuit breakers, but as far as their fuses go, I've been unable to come up with anything. Would anyone know where to look? Any help would be greatly appreciated.

    I'm sure you have thought of this, and maybe there are to many, but why not change them out for new fuses.

    Obtain all info from the fpe label
    contact a few current fuse mfgs and see if they can cross reference to a current product
    should be sufficient for your purpose

    That's a possibility but I would also include physical dimensions like mounting hole pitch and size, barrel diameter if round or width if square etc......
    Cooper Bussmann might be a good starting point. I had a binder with several hundred sheets and dozens of fuses per sheet. I know we got some equivalents to discontinued Ferraz fuses for example.
