DIMENSIONS

Please refer to the KLPC dimensions

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 —

While LDC series fuses’ UL Listed DC interrupting rating is

more than adequate for most applications (50,000 amperes at

a 16 millisecond time constant), tests in our high power

testing laboratory have shown that this remarkable fuse is

capable of performing at much longer time constants. This

makes the fuse uniquely suited for such applications as crane

rail circuits and mass transit systems. Contact the factory for

application information for special needs such as this.

For AC-only systems, consider the use of POWR-PRO^®

KLPC series fuses. They have a full ten seconds time-delay

at 500% rated current, and have a wider range of ratings.

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.

APPLICATIONS

UPS protection, especially for large battery circuits

DC distribution

ꢀ

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.

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
