KLPC Series POWR-PRO

600 VAC • Time-Delay • 200 – 6000 Amperes

KLPC series POWR-PRO fuses provide ideal overcurrent protection

for circuits from 200 through 6000 amperes. KLPC series POWR-PRO

fuses specification-grade construction and performance meet or exceed

the most stringent project specifications: 99.9% pure silver links, silver-

plated copper end bells, glass-reinforced melamine bodies, O-ring seals

between body and end bells, and granular quartz fillers.

KLPC series POWR-PRO fuses are the only UL listed Class L fuses

that provide a minimum of ten seconds time delay at 500% rated

current and are also as current-limiting as the fastest Class L fuse on the

market. On average, the peak let-through currents of KLPC series fuses

are 10% less than any other time-delay Class L fuse.

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

Primary and secondary protection for transformers

Protection of power circuit breakers

Features and Benefits

• Eliminate unnecessary downtime — KLPC POWR-PRO series time-

• Best protection for system components — Maximum current

• Coordinates with other system components — KLPC series fuses

• Eliminate need to oversize fuses — This may permit the use of smaller,

• 300kA Interrupting Rating — Littelfuse self-certified to 300,000

literature for recommended fuse rating.)

limitation means less equipment and system damage when short

circuits occur. Reduced damage means that electrical service can

be restored quickly, reducing costly downtime, and often permitting

equipment repair rather than replacement.

on the line and load side of the fuses. See the Fuseology section of
