Littelfuse® POWR-GARD® LLSRK040ID Current Limiting Time Delay Fuse, 40 A, 600 V AC/300 V DC, 200/20 kA Interrupt, RK1 Class, Cartridge Body
The all new LLSRK_ID series fuse is the most advanced Class RK1 fuse available today providing unparalleled performance and protection to modern circuits. The patented Indicator™ technology provides instant identification of a blown fuse greatly enhancing system up time, while the precision formed short circuit elements virtually eliminate damage to components from unexpected electrical faults. In addition, the all new solid state overload section has no moving parts, stopping unnecessary fatigue failures commonly found in other spring loaded fuses.

- This robust design withstands repeated surges within rated time delay without opening needlessly, eliminating downtime caused by power surges or equipment demands
- Reduce down time the indicating window of the LLSRK_ID immediately identifies the open fuse, if the window is dark, the fuse has opened, It's that simple, maintenance personnel can immediately determine that there is an open fuse
- Reduce fuse inventory the superior performance of the LLSRK_ID allows it to be used in a variety of applications, thus decreasing fuse inventory
- Reduce nuisance opening - indicator fuses offer superior time delay and cycling characteristics, which can lengthen fuse life
