General Purpose Fuses
KLLU Class L Fuses
600 VAC • Time-Delay • 601 – 4000 Amperes
Applications
Service switches
Switchboard mains and feeders
Bolted pressure contact switches
Motor control center mains
Large motor branch circuits
UL Listed series rated protection for molded case circuit breaker
panelboards and loadcenters. See panelboard manufacturers’
literature for recommended fuse rating.
Safety
• 200,000 A.I.R. — Provides reliable interruption of all overcurrents up
to 200,000 amperes.
• When used for motor branch circuit protection, KLLU fuses may be
sized close to the motor full load current, providing excellent protection
to branch circuit conductors, motor control equipment and motors.
Longer Equipment Life
• Current-Limiting — Reduces short-circuit damage to systems and
equipment.
• Reduced downtime.
• Ten second minimum time-delay at 500% current eliminates
needless downtime caused by heavy starting currents of large
motors and other inductive loads.
• Selective coordination — KLLU fuses coordinate well with other
Class L fuses and with all current-limiting Littelfuse fuses rated 600
amps or less. This means less time spent trying to locate short-
circuits or overloaded equipment, because only the fuse immediately
on the line side of the affected circuit opens.
KLLU series UL Listed, time-delay, Class L fuses are quality fuses,
developed to provide a somewhat lower priced alternate to the
POWR-PRO® KLPC series fuses. KLLU series fuses meet or exceed
all UL requirements for Class L fuses. For superior protection and
performance, specification-grade POWR-PRO KLPC series fuses are
the recommended fuse. Complete information on KLPC fuses may
be found in the POWR-PRO Fuse section of this catalog.
Easy To Use
• 200,000 A.I.R. rating minimizes need for short-circuit calculations,
while meeting present and future system requirements.
• KLLU fuse time-current characteristics closely match typical time-
current curves of circuit breakers. Although fuse/circuit breaker systems
can seldom be 100% coordinated, KLLU series fuses permit use of a
wider range of breaker setting than fast acting Class L fuses.
Excellent protection for a single breaker or a group of breakers.
