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.
*JLLS only
Note: Contact the factory for RoHS compliant Class T fuses.
