Fuse holder detection
Some evaluation criteria of this method:
1. After being energized for one hour at the rated current, the fuse will not blow out.
2. When energized at the rated current, the temperature rise of the fuse holder is less than 75 degrees.
3. When the fuse is energized with bidirectional rated current, the fuse will blow out within one minute.
4. After increasing the rated short-circuit capacity, continuous arc and ignition will not occur.
