Current-limiting Class L fuses are available in fast-acting and time-delay versions. Fuses in the LDC and KLPC series feature POWR-PRO® performance, and LDC series fuses are the first in this class of UL Class industrial fuses rated at 600 V ac and 600 V dc. Littelfuse also offers KLLU series Class L fuses with POWR-GARD® performance. Common applications include protecting circuits that carry loads as high as 6 kA for electrified crane rails, light rail systems, and large electric motors.

 

Features

  • Current ratings from 150 A to 6 kA
  • Interrupting ratings up to 20 kA to 480 V ac, 50 kA at 600 V dc, and 300 kA at 600 V ac

 

Benifits

  • Fast-acting and time-delay versions available
  • Maximum current limitation minimizes equipment and system damage from short circuits
Littelfuse KLPC Series

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...

Littelfuse KLLU Series

KLLU series UL Listed, time-delay, Class L are quality fuses in every sense of the word. They were developed to provide a somewhat lower priced alternate to the POWR-PRO™ KLPC series fuses. KLLU series fuses meet or exceed all UL requirements for Class L fuses. For superior protection and performance, specification-grade POWR-PRO™ KLPC series fuses are the recommended fuses.

Littelfuse LDC Series

Littelfuse POWR-PRO® LDC series Class L fuses represent another first in fuse protection. LDC series fuses are the first UL Listed 600 volts AC and DC Class L fuse. Since they may be used for both AC and DC, they eliminate the concern that AC only fuses may be inserted into DC circuits.
