Example part number (series & amperage): KLPC 1000

protection for circuits from 200 through 6000 amperes. KLPC

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.

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 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

s

Eliminate unnecessary downtime — KLPC POWR-

and keeps your circuits in service.

s

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.

s

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.

s

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.

s

300kA Interrupting Rating — Littelfuse self-certified to

300,000 amperes as standard. Meets future trend towards

higher available short circuit currents.
