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.
