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...

The FLSR_ID Indicator™ Series offers a patented, state-of-the-art, solid-state design with maximum reliability and superior performance characteristics. The dual-element design ensures advanced short-circuit and overload protection. This series offers...
