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.

Features:
  • 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.
