In order to select an appropriate fuse, make sure that the following items are satisfied.
1. 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.

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.





2. Rush Current Fuse Selection Method
Use the waveform closest to the actual measured waveform, and determine the joule integral value for rush current.
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 Resistance to rush current: 0.3
Please perform evaluation and confirmation of the selected fuse within actual equipment, including fuse operation under abnormal current application, before use.
