JLLN 300V Class T Fast-Acting POWR-GARD® Fuses

Littelfuse JLLN 300V Class T Fast-Acting POWR-GARD® Fuses are less than 1/3 the size of comparable Class R fuses and are typically used for short-circuit protection of drives and surge sensitive components. The fuses feature a melamine body with either bronze (1A to 30A) or copper (35A to 1200A) caps. When rated in accordance with the NEC, Littelfuse JLLN POWR-GARD Fuses provide fast-acting overload and short circuit protection for non-inductive circuits and equipment.
