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 noninductive circuits and equipment.

Applications

• Variable speed drive protection

• Compact mains switches
