JTD_ID Series -
UL Class J Time-Delay Fuses with Indication
The Littelfuse® POWR-PRO® JTD_ID Indicator Class J fuse provides
visual blown fuse indication and maximum protection 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 downtime 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:
Reduced 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 immediately determine that
there is an open fuse and request maintenance personnel to bring the
proper replacement.
Reduce nuisance opening — Indicator fuses have superior time-delay
and cycling characteristics they can be used on a variety of
applications, thus decreasing fuse inventory.
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.
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.
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 toolbox. Other forms of indication requires the power to
remain on, which causes a safety hazard for personnel.
