POWR-PRO® Class J Time-Delay Fuses – JTD Series

Littelfuse® POWR-PRO JTD Series Class J fuses feature a compact design for use in applications with limited space. JTD series’ current limiting time delay is a patented true dual-element design that is ideal for circuits with high inrush currents. The fuse is offered in two types: standard Class J Non-Indication design and Indicator design. The indication version allows for a quick visual identifier for an open fuse, which helps with increased safety as well as reduced downtime in pinpointing open fuses immediately.

Features

• Reduce nuisance opening: have superior time-delay and cycling characteristics so they can be used on a variety of applications, thus decreasing fuse inventory
• Reduce equipment damage: 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
• Indication and non-indication versions available
• Dual-element design

Applications

• Fused combination motor controllers to provide IEC Type II (no damage) motor branch-circuit short-circuit and ground fault protection
• 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
