Mark
Logo Most fuses are marked on the body or end cap with a marker indicating their rating. But the "chip type" fuse feature has little or no markings, making identification very difficult.
Fuses may appear similar to each other with significantly different characteristics that determine their marking. The fuse mark usually conveys the following information:
The rating of the fuse in amps
Voltage rating of fuses
Time-current characteristics, i.e. speed fuses
Approved by national and international standards bodies
Manufacturer/Product number/series
Interrupt capability
