LDC1400
FUS 600VAC/DC CLASS L 1450A | Series: LDC
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.

- All-purpose fuse rated at 600 V ac and 600 V dc reduces inventory requirements for special fuses is eliminated
- UL Listed for interrupting ratings of 200 kA at 600 V ac and 50 kA at 600 V dc, which minimizes the need for short-circuit studies
- Moderate 4 s time delay at 500 % of rated current allows fuse to withstand most harmless overloads or line surges
- Consider KLPC fuses for higher-voltage ac applications
- Coordinate well with all Littelfuse fuses rated up to 600 A and combining LDC and IDSR series fuses provides complete protection to 600 V dc system
- Extremely current limiting, which reduces damage to circuits and equipment
LDC1400 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, ships and dock cranes, etc.
- Mass transit systems, including new light rail applications
- General-purpose AC/DC circuits for mains, feeders and branch circuits
