POWR-PRO Fuses POWR-PRO Fuses LLSRK ID Series Indicator POWR-PRO Class RK1 Fuses 600 VAC Dual-Element, Time-Delay 1/10 600 Amperes Applications All general purpose circuits Motors Transformers Solenoids Fluorescent lighting All system components with high in-rush currents Features/Benefits Reduce downtime The indicating window of the LLSRK ID immediately identifies the open fuse. If the indicating strip is black, the fuse has opened. Its 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. Reduce equipment damage Indicator fuses provide superior overload and short-circuit protection that can reduce equipment damage. The LLSRK ID is extremely current-limiting and provides IEC Type 2 No Damage protection to IEC and NEMA type motor starters. Reduce accidents The LLSRK ID Indicator fuse improves safety The all new LLSRK ID series fuse is the most advanced Class RK1 by minimizing exposure to live circuits. Unlike other forms of blown fuse available today providing unparalleled performance and protection fuse indication, once the indicating strip darkens, it stays dark. Other to modern circuits. The patented Indicator technology provides instant forms of indication require the power to remain on, which causes a identification of a blown fuse greatly enhancing system up-time, while potential safety hazard to personnel. the precision formed short-circuit elements virtually eliminate damage to components from unexpected electrical faults. In addition, the all new Ordering Information solid-state overload section has no moving parts, stopping unnecessary fatigue failures commonly found in other spring loaded fuses. For online ordering use part number LSRK.
