    Old Curve data sheets for molded breaker types

    I have been looking for some of the old curve data sheets on older panels. Any advice or anyone have them they can share?

    Do you have the breaker CAT # and/or trip unit type? My company has a decent archive of trip curves for the breakers we have encountered.

    If the manufacturer doesn't have them available on their website you might have to call and ask for them.

    Do you have the breaker CAT # or trip unit model? You can try searching the manufacturer's website to see if they have the curve posted. If it's not on their website you might have to call them.

    If you can't find the trip curve, and you know the breaker CAT # or trip unit model send a pm or reply to the post and we might be able to help you.

    I have a fairly big collection of stuff, post the mfg & model # or trip unit type and I'll see what I got.

    Siemens doesn't seem to have a database, but they do give you some software to determine tcc

    Eaton/Cutler-Hammer/Westinghouse

    Square D

    Anything odd or older, you might be able to find on electricalmanuals.net
    http://www.electricalmanuals.net/

    Sometimes the breaker will have the curve no. printed on the label, and you can just google the specific curve number. As you will find there are multiple curve numbers for some breakers and the tcc curves do not always match. These typically will have the curve number printed on the breaker.
