The Littelfuse
POWR-PRO
JTD_ID Indicator Class J fuse
provides visual blown fuse indication and maximum protec-
tion in a compact package.The compact Class J package
was designed specifically for circuits where space is at a
premium.The current limiting time delay JTD_ID offers a
patented true dual-element design that is ideal for use in
circuits with high inrush currents. Superior performance
characteristics of JTD_ID Indicator fuses reduce nuisance
fuse opening and the blown fuse indication reduces down-
time and increases safety.
APPLICATIONS
Fused combination motor controllers to provide IEC Type II
(no damage) motor branch-circuit short-circuit and ground
fault protection
Motor control centers
Transformer protection
Protection for UL Listed series-rated molded case circuit
breaker panels
General purpose circuits
—
mains, feeders and branch
circuits
—
especially when space is at a premium
FEATURES/BENEFITS
I
Reduce down-time
—
A glance at the indicating window of
a JTD_ID Indicator fuse pinpoints open fuses immediately.
If the window is dark, the fuse has opened. It
’
s that simple.
No fuse testing required. Machine operators can immedi-
ately determine that there is an open fuse and request
maintenance personnel to bring the proper replacement.
I
Reduce nuisance opening
—
Indicator fuses have
superior time-delay and cycling characteristics which can
lengthen fuse life and decrease needless opening.
I
Reduce fuse inventory
—
Because JTD_ID Indicator
fuses have superior performance characteristics they can
be used on a variety of applications, thus decreasing fuse
inventory.
I
Reduce equipment damage
—
Indicator fuses provide
superior overload and short circuit protection that can
reduce equipment damage. Indicator fuses also provide
IEC Type II
“
No Damage
”
protection to IEC and NEMA type
motor starters.
I
Reduce accidents
—
The JTD_ID Indicator fuse improves
safety by minimizing exposure to live circuits. Unlike other
forms of blown fuse indication, once the indicator window
darkens, it stays dark. It does not matter if the power is on
or off or if the fuse is in a tool box. Other forms of indication
require the power to remain on, which causes a safety
hazard for personnel.
