RECOMMENDED FUSE BLOCKS
LR600 Series
Refer to Fuse Block section of this catalog for additional
information.
APPLICATIONS
All general-purpose circuits
Motors
Transformers
Solenoids
Fluorescent lighting
All system components with high in-rush currents
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
IndicatorTM 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/BENEFITS
ꢀ
Reduce equipment damage — Indicator fuses provide
ꢀ
Reduce down-time — The indicating window of the
superior overload and short-circuit protection that can
reduce equipment damage. The LLSRK_ID is extremely
current limiting and provides IEC Type II “No Damage”
protection to IEC and NEMA type motor starters.
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 accidents — The LLSRK_ID Indicator fuse
ꢀ
Reduce fuse inventory — The superior performance
improves safety by minimizing exposure to live circuits.
Unlike other forms of blown fuse indication, once the
indicator window darkens, it stays dark. Other forms of
indication require the power to remain on, which causes
a potential safety hazard to personnel.
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.
