Old ITE Trip Curves Requested - KC & KB Breakers

[Laplacian]

I have searched the web and thought I found a resource but they only have the cover image for the manuals, not the whole pdf. If anyone can provide curves or information about any (or all) of the following ITE documents, it would be greatly appreciated.

Various TCC curves for the K series breaker:
TD-3307C
TD-3308C
TD-3309C
TD-3304C
TD-3305C
TD-3306C
TD-3297
TD-3191
TD-3192

What is the OD model? The same OD's were used on lots of ITE breakers and thats what you really need.

Only the old ITE Molded Case breakers wer sold off to Siemens. The ITE POWER breaker product line (which included the K Series) was sold to BBC, who merged with Asea to form ABB. They now maintain the records for those breakers, I believe out of their Florence South Carolina plant.

I agree with Zogzog - if you are talking about the old non-solid-state (hydraulic) trip units, you need to provide a lot more information.

Most of these curves are in the EasyPower library, but I'd need to know which particular trip unit you need. There are a lot.

These are very early OD curve numbers, mid to late 50's. The 3304C through 3306C are MIN, INT and MAX respectively for the KA, KB and KC Dual Magnetic OD-1. The 3307C through 3309C are MIN, INT and MAX respectively for the KA, KB, KC and LG Dual Selective OD-2. All of these curves are contained in ITE IB-1300 (which I can send you a copy). I have no information on the remaining curves. I am sure Zog has them someplace.

ITE made a great product back then. I recall performing primary injection on about 60 KB and KC breakers with these trip units a couple of years ago. They were installed in the late 50's and never touched. Over 95% of the trip units worked perfectly. No extras on that job.
