In-line Fuse Holders

Electrical In-Line & Panel Mount Fuse Holders

In-line fuse holders install along wiring harnesses to put overcurrent protection in places where fuse blocks will not fit or where routing cables to a junction box would prove impractical. Littelfuse makes in-line fuse holders that fit most types of fuses used in automotive, industrial, lighting, telecommunications, and power generation and transmission applications. Off-the-shelf options include waterproof and indicating holders. We can also partner with you to design a customized in-line holder.
