POWR-PRO® Fuses
LDC Series POWR-PRO® Class L Fuses
600 V AC/DC Time-Delay • 150 – 2000 Amperes
constants. This makes the fuse uniquely suited for applications such
as crane rail circuits and mass transit systems. Contact the factory for
application information.
For AC only systems, consider the use of POWR-PRO KLPC series
fuses. They have a full 10 seconds time-delay at 500% rated current,
and have a wider range of ratings.
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
Features/Benefits
•

•
600 Volt AC/DC rated — “All-purpose” Class L fuses reduce
inventory requirements because the need for separate AC and DC
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.
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 fuses. Since they may be used for both
AC and DC, they eliminate the concern that AC only fuses may be
inserted into DC circuits.
•
•
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.
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 laboratory have shown that
this remarkable fuse is capable of performing at much longer time
