JLS Series - UL Class J Fast-Acting Fuse
Brand: Littelfuse, IncJLS series fuses provide space-saving, fast-acting overload and short-circuit protection for non-inductive loads. When used for motors or other inductive loads, the ampere rating of JLS series fuses must be increased to prevent nuisance opening on inrush currents.
In such applications, JLS fuses may provide only short circuit protection. Consider using Littelfuse POWR-PRO™ JTD series time-delay fuses in such circuits.
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
