WebOct 3, 2014 · The fuse in Figure 1 is a 125E-rated fuse. Note that the curve starts at approximately 250 A for a minimum melting time of 1000 s. … WebAug 11, 2024 · Fuse current ratings are measured at 23˚C but since a fuse is rarely operated at this temperature, ‘derating’ of the rated current is usually necessary. The higher the ambient temperature, the quicker the fuse will blow, so a higher amperage is necessary. Taking the example of SCHURTER’s UMT 250 series of time-lag SMD fuses. When the ...
