POWR-PRO® Class L Fuses 600 V AC/DC 150 –2000 Amperes

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.

FEATURES/BENEFITS
■ 600 Volt AC/DC rated —“All-purpose”Class L fuse reduces
   inventory requirements because the need for
   special fuses is eliminated.
■ UL Listed 200,000 A.I.R. AC –50,000 A.I.R. DC — Reliable interruption of all overcurrents
   up to their ratings.
   Minimizes the need for time-consuming and expensive short-circuit studies.
■ Moderate time delay — Four seconds time delay at 500% current provides adequate time-delay
   for many AC applications and most DC applications.
   They will withstand most harmless overloads or line surges. If your needs
   exceed the LDC capabilities, consider the use of KLPC fuses for AC applications.
■ Selective coordination — LDC series fuses coordinate well with all Littelfuse fuses rated 600
   amperes or less.
   A combination of LDC and IDSR series fuses provide a complete 600 volt rated DC system.
■ Extremely current limiting — Maximum current limitation reduces damage to circuits and
   equipment under short circuit conditions. Stops damaging short circuits faster than any   
   mechanical protective device.

APPLICATIONS
UPS protection, especially for large battery circuits
DC distribution
DC variable speed drives
Protection of crane rail circuits and other large DC equipment such as electrical power shovels, ship and dock cranes, etc.
Mass transit systems, including new light rail applications
General-purpose AC/DC circuits for mains, feeders, and branch circuits
