Class J Fuses
JTD_ID Series Indicator ®
600 V ac • Time Delay • 8⁄10 –600 A
Description
The JTD_ID Indicating* Series fuses provide visual blown indication and maximum protection in a compact size. These
time-delay, dual-element fuses carry the Littelfuse POWR-PRO® advanced technology designation and are specifically
designed for circuits where space is at a premium. They are ideal for use in systems with high in-rush currents. The
JTD_ID fuses offer a patented design that reduces nuisance fuse openings. In addition, they provide Type 2 “No Damage”
protection for both NEMA- and IEC-type motor circuit components. These fuses help lower the costs associated with
downtime, provide longer fuse life by minimizing nuisance openings, increase system performance by minimizing
equipment damage, and improve safety by minimizing accidents.
The POWR-PRO performance brand offers advanced technology protection features, such as self-certification to
300,000 A rms symmetrical and superior current-limiting capability. The self-certification at 300,000 A meets the current
trend toward higher short-circuit current ratings (SCCR). Self-certification testing was conducted at a nationally recognized
testing laboratory, and the tests were UL witnessed. The POWR-PRO design also includes blown fuse indication for
maximum security and protection.
*Also available in non-indicating version
