Littelfuse JLLS500

The JLLS500 - JLLS Series features a space-saving design, making it the smallest fuse option for applications requiring ratings above 30 amperes, with dimensions less than one-third that of comparable Class R fuses. When utilized in accordance with the NEC, these Class T fuses deliver swift overload and short circuit protection specifically tailored for non-inductive circuits and equipment.

In scenarios where inductive circuits are involved, an increase in the ampere rating is recommended to prevent premature opening due to inrush currents. In such cases, the Class T fuses may solely offer short circuit protection. For motor and general-purpose circuits where spatial constraints are less of a concern, alternative options such as the POWR-PRO™ JTD_ID Indicator series or LLNRK/LLSRK series may be suggested.

With an ampere rating of 500A, these fuses operate at a voltage of 600VAC and 300VDC, featuring a fast-acting opening mechanism and an interrupting rating of 20000A at 300VDC. The package size is designed for knife-blade or bolt-in installations.
