Rerating depicted in this curve is in addition to the standard derating of 25% for continuous operation. Example: For continuous operation at 70°C, the fuse should be re-rated as follows: I = (0.75)(0.90)IRAT = (0.675)IRAT 2. The temperature re-rating curve represents nominal conditions. For questions about the temperature re-rating curve, please consult Littelfuse technical support assistance.
