Oduct Offering: Multiples of Current Rating

The document provides two charts showing multiples of current ratings at different temperatures over time. The charts show minimum and maximum clearing times in seconds for currents ranging from 0.5 to 50 times the rated current at temperatures of 0°C, 10-50°C, and 60°C. Notes below the charts indicate they are for 70 Ampere and 100 Ampere ratings.
