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 letthrough 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 fuses’ 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, and, since the
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.
