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.
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.

Features: 풍모:
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 AIR AC – 50,000 AIR 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.
