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
