JTD_ID Series Indicator
600 VAC • Time Delay • 8/10 – 600 Amperes
The Littelfuse POWR-PRO JTD_ID Indicator Class J fuse provides visual
blown fuse indication and maximum protection in a compact package.
The compact Class J package was designed specifically for circuits
where space is at a premium. The current-limiting time delay JTD_ID
offers a patented, true dual-element design that is ideal for use in circuits
with high, in-rush currents. The Superior performance characteristics of
JTD_ID Indicator fuses reduce nuisance fuse opening, and the blown
fuse indication reduces downtime while increasing safety.

by minimizing exposure to live circuits. Unlike other forms of blown
fuse indication, once the indicating window darkens, it stays dark. It
does not matter if the power is on or off or if the fuse is in a tool box.
Other forms of indication require the power to remain on, which is a
safety hazard for personnel.
