This document appears to contain technical specifications and settings for electrical circuit breakers including their current ratings from 0.01 kA to 100 kA and time ratings from 0.01 s to 1000 s. It also lists the voltage ratings as 69kV and 115kV and includes measurements for two circuit breakers - OC-57 rated at 83A and 0.05pu time, and OC-69 rated at 75A and 0.08pu time, both using IEC255-3 normal inverse characteristics.
