Littelfuse Class L Fuses

KLPC Series

Littelfuse’s KLPC series POWR-PRO fuses meet the most stringent project specifications, including silver links, silver-plated copper end bells, glass-reinforced melamine bodies. O-ring seals between body and end bells and granular quartz fillers. 

Littelfuse KLPC Series Fuse by GD Rectifiers

Amperage range (A): 200 – 6,000A

Voltage ratings (Vac): 600V

Voltage ratings (Vdc): 480V

Datasheet

 

Features:

-       Eliminates unnecessary downtime

-       Provide best protection for system components

-       KLPC POWR-PRO series fuses’ time delay withstands system surges and keeps circuits in service

-       Maximum current limitation means less equipment and system damage when short circuits occur

-       KLPC series provides maximum coordination with fuses and circuit breakers both on the line and load side of the fuses

 

Applications:

-       Service switches

-       Switchboard mains and feeders

-       Bolted pressure contact switches

-       Motor control center mains

-       Large motor branch circuits

-       Primary and secondary protection for transformers

-       Protection of power circuit breakers

-       UL listed series-rated protection for molded case circuit breaker panel boards and load centres

 

KLLU Series

The KLLU series fuses meet UL requirements for UL Class L fuses and provides a cost-effective alternative to KLPC POWR-PRO fuse with a slightly higher peak let through current.
