JLLN/JLLS fuses are less than

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.

Applications

• Variable speed drive protection

• Compact mains switches

Features/Beneﬁts

• Extremely current-limiting

• Compact design

• 200 kA Interrupting Rating
