Fuse Holders

Littelfuse/Commercial Vehicle Products in-line fuse holders offer a flexible, quick solution for placing fuses in cramped spaces or adding overflow or accessory circuits for low-current applications, such as electronics, panel displays, blower motors, air conditioners, and lighting. The Littelfuse portfolio includes in-line fuse holders for ATO®, MINI®, MAXI®, JCASE®, MIDI®, and glass fuses with various wire lead sizes, colors, and lengths to accommodate industry guidelines and applications with and without covers and with and without waterproof ratings.

Bolt-down and fuse blocks are ideal for high-current applications, such as battery and alternator connections and starter fusing, when requirements dictate the use of larger fuses like MEGA®, MIDI, and ZCASE®. Because of their larger size and placement requirements, these fuses typically need a bolt-down fuse holder or multi-fuse block to house and protect them from harsh conditions. For these applications, Littelfuse offers battery mount, stud mount, and bolt-down fuse holders with and without waterproof and ignition protection ratings. Littelfuse also offers fuse blocks and boxes for high-amperage fuses, such as MEGA and MIDI, and low-amperage fuses, such as ATO and MINI, designed for efficient multi-fuse installation and power distribution.

Printed circuit board (PCB) fuse holders are ideal for automotive PCB applications, such as protecting circuits for vehicle control systems, navigation and entertainment systems, and automotive sensors. Littelfuse offers a variety of heat-resistant thermoplastic PCB fuse holders that accept MINI and ATO fuses. These fuse holders have a UL 94 V-0 flammability rating and innovative, purpose-driven designs. Features like circuit board locking anchors for secure attachment, standoffs to accommodate washing, and various stacking and mounting options (model features vary) make finding the right PCB fuse holder for applications simple.
