Littelfuse® POWR-GARD® JTD450 Current Limiting Time Delay Fuse, 450 A, 600 V AC/500 V DC, 200/20 kA Interrupt, J Class, Cartridge Body
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 inrush currents. Superior performance characteristics of JTD_ID Indicator fuses reduce nuisance fuse opening and the blown fuse indication reduces downtime and increases safety.

- Reduced down time - A glance at the indicating window of a JTD_ID indicator fuse pinpoints open fuses immediately
- Machine operators can immediately determine that there is an open fuse and request maintenance personnel to bring the proper replacement
- Reduce nuisance opening - indicator fuses have superior time-delay and cycling characteristics they can be used on a variety of applications, thus decreasing fuse inventory
- Reduce fuse inventory - Because JTD_ID indicator fuses have superior performance characteristics they can be used on a variety of applications, thus decreasing fuse inventory
- Reduce equipment damage - indicator fuses provide superior overload and short circuit protection that can reduce equipment damage
- Indicator fuses also provide IEC type II "No Damage" protection to IEC and NEMA type motor starters
- Reduce accidents the JTD_ID indicator fuse improves safety by minimizing exposure to live circuits
- IEC type 2 protection
- 200 kA rms symmetrical at 600 VAC/20 kA at 500 VDC
