POWR-PRO Fuses POWR-PRO Fuses JTD ID Series Indicator POWR-PRO Class J Fuses 600 VAC Time Delay 8/10 600 Amperes Applications Fused combination motor controllers to provide IEC Type 2 (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 limited. Features/Benefits Reduce downtime A glance at the indicating window of a JTD ID Indicator fuse pinpoints open fuses immediately. If the indicating window is dark, the fuse has opened. Its that simple. Reduce nuisance opening Indicator fuses have superior time-delay and cycling characteristics which can lengthen fuse life and decrease needless opening. Reduce fuse inventory JTD ID Indicator fuses have superior performance characteristics, which means they can be used on a variety of applications therefore, 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 2 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 The Littelfuse POWR-PRO JTD ID Indicator Class J fuse provides visual fuse indication, once the indicating window darkens, it stays dark. It blown fuse indication and maximum protection in a compact package. does not matter if the power is on or off or if the fuse is in a tool box. The compact Class J package was designed specifically for circuits Other forms of indication require the power to remain on, which is a where space is at a premium. The current-limiting time delay JTD ID safety hazard for personnel. offers a patented, true dual-element design that is ideal for use in circuits with high, in-rush currents. The Superior performance characteristics of JTD ID Indicator fuses reduce nuisance fuse opening, and the blown fuse indication reduces downtime while increasing safety.
