Class L Fuses
600 VAC • Time-Delay • 200 – 6000 Amperes
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
panelboards and loadcenters. (See panelboard manufacturers’
literature for recommended fuse rating.)
Primary and secondary protection for transformers
Protection of power circuit breakers
Features and Benefits
• Eliminate unnecessary downtime — KLPC POWR-PRO series time-
delay withstands system surges and keeps your circuits in service.
• Best protection for system components — Maximum current
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.
• Coordinates with other system components — KLPC series fuses
provide maximum coordination with fuses and circuit breakers both
on the line and load side of the fuses. See the Fuseology section of
this catalog for additional information.
• Eliminate need to oversize fuses — This may permit the use of smaller,
less expensive switches. Since lower rated fuses are more current-
limiting, equipment receives even better protection.
• 300kA Interrupting Rating — Littelfuse self-certified to 300,000
amperes as standard. Meets future trend towards higher available
short circuit currents.
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
