Old Westinghouse Breaker Data Needed

Old Westinghouse Breaker Data Needed

Old Westinghouse Breaker Data Needed

(OP)
I'm looking for interrupting data on some very old Westinghouse molded case circuit breakers.  Namely:

Type F
Type G
Type J

I believe these pre-date the two letter designations for Westinghouse breakers such as "FB" that are much more familiar.  These are circa 1950.  

If anyone has any data, I'd appreciate hearing from you.  I do have a request into Eaton-Cutler-Hammer (or whatever their name is today) as well.  

TIA.

RE: Old Westinghouse Breaker Data Needed

Type F per Publication 29-160 (3/65)

V   AS   S
240/20KA/18KA
480/15KA/14KA
600/15KA/14KA
250DC/10KA

Will look for the others

Thanks for the info.  I did find the time-current curves on the Eaton website, which I thought was pretty amazing, but couldn't dig out the interrupting ratings.
