The MIDI® 498-IL Series 58 V In-Line Fuse Holder can be installed directly in line with the cables to provide high-amperage main or branch circuit protection in harsh or hazardous environments. Because there's no need to mount the fuse holder, it saves both time and space.

With a curved cover that helps prevent tube splitting, the MIDI® 498-IL Series fuse holder is specifically designed for use with heat shrink tubing (sold separately) in applications that need added splash protection.

This high-amp automotive fuse holder features a UL 94 V-0 rated glass-filled nylon base and cover and accepts M5 MIDI® bolt-down fuses rated up to 200 amps.
