481 Series Alarm Indicating Fuse
Description
481 Series alarm indicating fuses are designed to reduce
down time by immediately pinpointing the blown (open)
circuit while triggering an LED or audio alarm. This item
requires 482 Series mating fuse holder.
All ranges of 481 Series fuses are available as our original
design, and the 2-20 amp range is now available as a RoHS
compliant option (use the “P” designator when ordering).
See the part numbering section of this data sheet for related
ordering instructions.
