Refer to Fuse Block section of this catalog for additional
information.
The Littelfuse IDSR Indicator™ fuse is the first indicating
power fuse ever. Its solid-state design provides state-of-the-art
reliability; it will forever change the way you look at modern
circuit protection.
FEATURES/BENEFITS
ꢀ
Patented design fuses — The first totally new dual-
element time-delay Class RK5 fuses in 10 years. They look
different because they are different! Even the Littelfuse
SLO-BLO® fuse, the fuse that set new standards for dual-
element fuses when it was introduced in 1984, cannot
match the performance of POWR-PRO® IndicatorTM fuses.
Money is wasted each time a circuit opens and halts produc-
tion. Thousands of dollars can be lost with every minute spent
testing to discover the cause.
The Littelfuse IDSR IndicatorTM fuse offers you a better way.
Just a simple glance at the IDSR Indicator’s window tells
which circuit is open. The circuit can be tested and any
problem corrected without unnecessary delay. No time
wasted finding the faulted circuit. No system damage. And no
costly down time.
ꢀ
Pinpoint open fuses immediately — A glance at the
window tells if the fuse has blown. If the window is dark, the
fuse has opened. It’s that simple. No fuse testing required.
ꢀ
Reduce down-time — Machine operators can immediately
determine that there is an open fuse and request mainte-
nance personnel to bring the correct replacement.
Superior time delay — POWR-PRO® IndicatorTM fuses
APPLICATIONS
ꢀ
provide superior time delay to override current surges
without sacrificing protection for sustained overloads. This
superior time delay is achieved by a remarkable advance in
the science of fuse design. Littelfuse-patented leading edge
metallurgy eliminates all moving parts in a true dual-
element fuse.

FUSES
ꢀ
Excellent cycling — Reduces the possibility of fatigue
failure. Like the spring-loaded designs such as Littelfuse
SLO-BLO® series, if an overcurrent does not open an
IndicatorTM fuse, it is not weakened. In addition, the superior
time delay further reduces the possibility of any type of
fatigue.
ꢀ
Excellent current limitation — IDSR fuses have much
lower peak let-through currents and I2t than permitted by UL
Standards for RK5 fuses. The IDSR provides IEC
Type II protection of NEMA motor starters without the high
cost of RK1 fuses. When IEC controllers are used, one of
the first considerations is reduced size. In those cases,
space-saving POWR-PRO® time delay Class J fuses or
Class CC fuses meet most needs.
ꢀ
300kA Interrupting Rating — Littelfuse self-certified to
300,000 amperes as standard. Meets future trend towards
higher available short circuit currents.
ꢀ
Low watts loss — The patented overload element design
results in lower cold and hot resistance. POWR-PRO®
IndicatorTM fuses have extremely low watts loss. They are not
only less costly to buy than RK1 fuses, but they are less
costly to operate.
ꢀ
600 V AC/DC rated — Unlike most RK5 fuses and all RK1
fuses, POWR-PRO® IndicatorTM fuses have full voltage AC/
DC ratings. Use them anywhere in your facility without
worrying whether they will perform.
