Steady-State Current Fuse Selection Method 1-1. Derating Coefficient for Steady-State Current: 0.7 Fuse use is predicated on usage at currents of 70% or less of their rated current. 1-2. Temperature Derating Coefficient: Multiply the derating for steady-state current by the effect of the ambient temperature. Ambient temperature -20 20 40 SP4 1.14 1 0.92 1-3. Derating for multiple fuse use: When mounting multiple fuses, heat generation must be taken into account. Please consult with us in advance. The following formula is used to determine the required rated current value for the fuse. Circuit Steady-State Current Value Rated Current Value Derating Coefficient for 1 Steady-State Current x Required Derating Sum * P SP *1 This is calculated by multiplying all necessary deratings together. 2. Rush Current Fuse Selection Method Use the waveform closest to the actual measured waveform, and determine the joule integral value for rush current (refer to P8, e.g. triangular waveform). In order to select a fuse for the determined rush current, assuming a fuse rush current durability of 100,000 times, ensure that the selected fuse fits the relationship below. I2t of fuse breakage > I2t of rush current / resistance to rush current *2 *2 Rush resistance coefficient: Select the 10 5 value from the graph to the left. 0.2 0.1 10 102 103 104 105 Repeat numbers to rush current Cat.
