L25S Series - Traditional Semiconductor Fuse

Brand: Littelfuse, Inc

The L25S Series is a traditional North American Bolted style high-speed fuse for protection of power semiconductor devices that are rated up to 250 Vac and 200 Vdc.

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 fast-acting, current-limiting fuses are used with no time delay required.
