The L15S series is a traditional North American Bolted style high-speed fuse for protection of power semiconductor devices that are rated up to 150 V ac and up to 150 V dc Littelfuse POWR-SPEED ® products offer optimized circuit protection at the extremely fast speed required to protect power semiconductor devices such as silicon controlled rectifiers (SCR’s), diodes, thyristors, triacs, transistors, and similar solid-state devices. These devices are used in power equipment including variable speed drives, power rectifiers, UPS systems, dc power supplies, and in a wide range of electronic equipment. May be used wherever extremely fastacting, current-limiting fuses with no time delay are required.

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.

KLPC series POWR-PRO™ fuses provide ideal overcurrent protection for circuits from 200 through 6000 amperes. KLPC series POWR-PRO™ fuses specification-grade construction and performance meet or exceed the most stringent project specifications: 99.9% pure silver links, silver-plated copper end bells, glass-reinforced melamine bodies, O-ring seals between body and end bells, and granular quartz fillers. KLPC series POWR-PRO™ fuses are the only UL listed Class L fuses that provide a minimum of ten seconds time delay at 500% rated current and are also as current limiting as the fastest Class L fuse on the market. On average, the peak let-through currents of KLPC series fuses are 10% less than any other "time-delay" Class L fuse.

FLNR.600 is a Class RK5 fuse with an ampere rating of 0.6 and cartridge-style construction.
