Description
JLLN / JLLS series 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.

Features/Benefits
Extremely current-limiting
Compact design
200 kA interrupting rating
JLLN 35–60 amperes available with PCB mounts

Applications
Variable speed drive protection
Power conversion devices (inverters, rectifiers, UPS)
Power supplies and power distribution units
Compact mains switches
