To be certain a fuse is the proper type, check the technical manual for the equipment. The parts list will show you the proper fuse identification for a replacement fuse. Obtain the exact fuse specified, if possible, and check the identification number of the replacement fuse against the parts list.
If you cannot obtain a direct replacement, use the following guidelines:
- Never use a fuse with a higher current rating, a lower voltage rating, or a slower time delay rating than the specified fuse.
- The best substitution fuse is a fuse with the same current and time delay ratings and a higher voltage rating.
- If a lower current rating or a faster time delay rating is used, the fuse may open under normal circuit conditions.
- Substitute fuses must have the same style (physical dimensions) as the specified fuse.
