IDSR Series -
UL Class RK5 Dual-Element Time Delay Fuses With Indication
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.
Money is wasted each time a circuit opens and halts production.
Thousands of dollars can be lost with every minute spent testing to
discover the cause.
The Littelfuse IDSR Indicator™ fuse offers you a better way. Just a
simple glance a 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.
Applications:
All general-purpose circuits
Motors
Transformers
Solenoids
Fluorescent lighting
All system components with high inrush currents
Features:
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®
Indicator™ fuses.
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 maintenance personnel to bring
the correct replacement.
Superior time delay — POWR-PRO® Indicator™
fuses 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.
