What is a DC fuse?
DC fuses require faster current interruption to prevent continuous arcing. The principle of ‘melting and
clearing’: When the current exceeds the rated capacity of the AC or DC fuse, the melting element will heat

high requirements for the melt, commonly using 99.99% silver, which is costly
