Bussmann time delay fuse

FNQ-R-1/2

Mainly used in conjunction with transformers, widely used in Tesla supercharging stations

The original production capacity cannot meet market demand, resulting in a shortage of low current products in the market

Low current fuses cannot be tested for resistance using a multimeter,

The multimeter detects the resistance value, and if the initial voltage is too high, the instantaneous current will cause the fuse to blow

The factory inspection of fuses is to detect the resistance value, and the standard resistance value has an acceptable range of up and down 10%. If it exceeds 10%, it will be judged as a defective product,

fuse ratings: 500v, 0.5amp;
