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. 

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.

 

Amperage range (A): 601 – 4,000A

Voltage ratings (Vac): 600V

Voltage ratings (Vdc): 300V

Datasheet

 

Features:

-       Current limiting

-       Easily coordinated with other system components

-       200kA AC interrupting rating

 

Applications:

-       Service switches

-       Switchboard mains and feeders

-       Motor control centre mains

-       Large motor branch circuits

-       Circuit breaker protection

  

LDC Series

Littelfuse’s LDC series is an ideal fuse for DC applications because of it’s high DC voltage and interrupting ratings. The DC interrupting performance exceeds UL listing requirements.

 

Amperage range: 150 – 2,000A

Voltage ratings (Vdc): 600V

Datasheet

 

Features:

-       POWR-PRO performance

-       Extremely current limiting

-       600Vac/dc rated

-       200kA AC interrupting rating

-       50kA DC interrupting rating

 

Applications:

-       Solar inverter and array protection

-       UPS protection

-       DC distribution and variable speed drives

-       Mass transit systems
