RECOMMENDED FUSE BLOCKS
LT300 series (for JLLN series fuses)
LT600 series (for JLLS series fuses)
Refer to Fuse Block section of this catalog for additional infor-
mation.
I
Extremely current limiting
—
Stops damaging short circuit
current faster than any mechanical protective device.
I
Fast-acting
—
Provides fast-acting overload protection to
equipment such as variable speed drives, rectifiers and
other equipment containing surge-sensitive components.
LONGER EQUIPMENT LIFE
I
Current limiting design greatly reduces damage to equip-
ment caused by heating and magnetic effects of short
circuit currents.
ECONOMICAL
I
Extremely current limiting design often permits use of
readily available, less costly equipment.
I
Used as input or output fuses for surge-sensitive compo-
nents, such as variable speed drives and rectifiers, fast-
acting POWR-T JLLN/JLLS fuses may prevent opening of
expensive semiconductor fuses protecting individual
components.
NOTE:
JLLN Class T 300 volt fuses are UL listed for circuits
not exceeding 300 volts to ground. However, since UL does
not include testing 300 volt Class T fuses on 277/480 volt
three-phase bolted faults, Littelfuse does not recommend
using 300 volt Class T fuses where phase-to-phase voltage
exceeds 300 volts.
Space saving POWR-T
fuses are the most compact fuses
available in ratings above 30 amperes
—
less than one-third
the size of comparable Class R fuses.When rated in accor-
dance with the NEC, POWR-T fuses provide fast-acting
overload and short circuit protection for non-inductive circuits
and equipment. Used in inductive circuits, the ampere rating
of POWR-T fuses must be increased to prevent opening on
inrush currents. In such instances, POWR-T fuses may
provide only short circuit protection.
For motor and general purpose circuits where space is not
critical, we recommend POWR-PRO
JTD_ID Indicator
series, LLNRK/LLSRK series, or FLSR_ID Indicator series.
APPLICATIONS
Protection of individual electric services and meters.
Main switches containing Class T fuses may be used to
provide compact protection for meter stacks.
Molded case circuit breaker load centers and panelboards
have increased interrupting ratings when
“
series rated
”
with
Littelfuse Class T fuses. Refer to panelboard manufacturers
’
literature for UL Listed combination of fuses and panelboards.
Series ratings up to 200,000 amperes are available.
SPACE-SAVING
Typical three-pole Class T fuse blocks require less than 50%
of the panel area required for Class R fuse blocks. Switch
enclosures, fuse pullouts, and other equipment using Class T
fuses are often correspondingly more compact.
