Description
JLLN / JLLS 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.
When rated in accordance with the NEC®, JLLN / JLLS
fuses provide fast-acting overload and short circuit
protection for non-inductive circuits and equipment.
