Description
JLS
JLS series fuses provide space saving, fast-acting overload
and short-circuit protection for non-inductive loads.
For ap­pli­ca­tions where short-duration surg­es and spikes may
cause nuisance fuse opening, consider the use of Littelfuse
POWR-PRO® JTD or JTD_ID series time-delay fuses.

PEAK LET-THRU IN AMPERES
• General purpose circuits with little or no motor load.
• Resistive loads, such as resistance electric heat.
• Loads requiring fast-acting overload protection, such as
equipment containing solid-state devices.
