Description

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.
