The difference between DC fuses and AC fuses
DC fast fuses can replace AC fast fuses, and vice versa
thanks to the rapid melting of the fuse and the diffusion of quartz sand adsorption and cooling forced to extinguish the arc, so it is much more difficult than breaking the AC
any waveform of DC does not exist in the zero, in the open DC short-circuit fault current
Alternating current is a sinusoidal waveform alternating conduction, the weekly wave has a zero, then the minimum value of electricity is very easy to extinguish the arc
DC fuses and AC fuses are part of the current limiting fuse, the shape is very similar, but the breaking current process is very different:
