The CCMR Series dual-element, time-delay fuses carry the Littelfuse POWR-PRO® advanced technology designation. These fuses are ideal for space-saving protection of motor circuits up to 40 hp* and are specifically designed to withstand sustained starting...

The FLSR series dual-element, time-delay UL Class RK5 fuses are the most widely used fuse class. They offer superior performance and excellent protection for all types of circuits, especially those with motors. Precision manufactured parts ensure an...

The SPF Solar Protection Fuse series has been specifically designed for the protection of photovoltaic (PV) systems. This family of midget-style fuses (10 x 38 mm) can safely protect PV modules and conductors from reverseovercurrent conditions. As PV...

The L15S series is a traditional North American bolted-style, high-speed fuse designed with POWR-SPEED® technology for protection of power semiconductor devices that are rated up to 150 V ac and up to 150 V dc. This is a round body, extremely...

The FLNR series sets the standard for general purpose fuses. The dual-element design provides advanced short-circuit and overload protection. These time-delay fuses are also available in an indicating version, see FLNR_ID series.

Littelfuse LLNRK and LLSRK series POWR-PRO™ fuses provide superior overload and short circuit protection for service entrance, main, feeder and general-purpose branch circuits up to 600 amperes.

The KLK series fast-acting fuses are designed specifically for the protection of control circuits, street lighting, HID lighting, computers, and other applications without high in-rush currents. These midget fuses also have high-interrupting and...

The BLS series fast-acting fuses are 13 ⁄8" long in comparison to other midget fuses, which are 1½" long. They provide space-saving, low-cost protection for street lighting, metering, control and electronic circuits. These fuses open circuits quickly...
