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
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
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 (Vac): 600V
Voltage ratings (Vdc): 600V
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
