Re-rating depicted in this curve is in addition to the standard re-rating of 25% for continuous operation. Example: - For continuous operation at 70 degrees celsius, the fuse should be rerated as follows: - I = (0.75)(0.80)IRAT = (0.60)IRAT 2. The temperature derating curve represents the nominal conditions.
