LLSRK_ID Series Indicator
600 VAC • Dual-Element, Time-Delay • 1/10 – 600 Amperes
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.

the fuse has opened. It’s that simple. Maintenance personnel can
immediately determine that there is an open fuse.

by minimizing exposure to live circuits. Unlike other forms of blown
fuse indication, once the indicating strip darkens, it stays dark. Other
forms of indication require the power to remain on, which causes a
potential safety hazard to personnel.
