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
