Notes: - l2t calculated at 8ms. Resistance is measured at 10% of rated current, 23ºC
Temperature Derating Curve
Notes:
1. Derating depicted in this curve is in addition to the standard derating of 20% for continuous operation.
Example:For continuous operation at 75 degrees celsius, the fuse should be derated as follows:I = (0.80)(0.85)IRAT= (0.68)IRAT
