RECOMMENDED FUSE BLOCKS
LJ600 series
Refer to Fuse Block section of this catalog for additional infor-
mation.
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 inrush currents. In such applications, JLS fuses
may provide only short circuit protection. Consider using
Littelfuse POWR-PRO® JTD series time-delay fuses in such
circuits.
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.
APPLICATIONS
ꢀ
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.
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.
EASY TO USE
ꢀ
200,000 A.I.R. rating minimizes need for short-circuit
calculations.
SPACE SAVING
ꢀ
JLS fuse characteristics are similar to KLNR/KLSR fast-
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 series time-delay fuses.
acting Class RK1 fuses, but they 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 equip-
ment containing surge-sensitive components.
