General Purpose Fuses
JLS Class J Fuses
600 VAC • Fast Acting • 1 – 600 Amperes
JLS series fuses provide space saving, fast acting overload and short-
circuit protection for non-inductive loads. When used for motors or other
inductive loads, the ampere rating of JLS series fuses must be increased
to prevent nuisance opening on in-rush currents. In such applications, JLS
fuses may provide only short-circuit protection. Consider using Littelfuse
POWR-PRO® JTD or JTD_ID series time-delay fuses in such circuits.
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.
Space Saving
• JLS fuse characteristics are similar to KLNR/KLSR fast acting Class
RK1 fuses, but dimensionally are much smaller.
Safety
• 200,000 A.I.R. — Reliable interruption of all overcurrents up to
200,000 amperes.
• Extremely current-limiting — Stops damaging short-circuit current
faster than any mechanical protective device.
• Fast acting — Provides fast acting protection to equipment such as
variable speed drives, rectifiers and other equipment containing surge
sensitive components.
Longer Equipment Life
• Current-limiting design reduces damage to equipment caused by
heating and magnetic effects of short-circuit currents.
Economical
• Extremely current-limiting design often permits use of readily
available, less costly equipment.
• Manufacturers of equipment containing dual voltage devices can
simplify manufacturing and reduce inventory by standardizing on 600
volt JLS fuses and Class J fuse blocks for all AC voltage ratings.
Easy to use
• 200,000 A.I.R. rating minimizes need for short-circuit calculations.
NOTE: Littelfuse JLS fuses are not time-delay fuses. 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.
