Sign

Signs most fuses are marked on the body or end caps with markings indicating their rating. But the "chip type" fuse features little or no marking, making it very difficult to identify.

The fuses may have similar markedly different properties, identifying their markings. Fuse marks usually convey the following message:

Ampere's fuse rating

Voltage grade fuse

Time-current characteristic, i.e. speed fuse

Approved by national and international standards bodies

Manufacturer/Product Number/Series

Interrupt capability
