Class L Fuses
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.
  • 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
  • Fast-acting and time-delay versions available
  • Maximum current limitation minimizes equipment and system damage from short circuits
