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