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
