OptiFuse was founded in 2000 as an alternative manufacturer to Littelfuse and Bussmann. Prior to 2000, OptiFuse had designed and manufactured around 150 different products for Littelfuse, Bussmann and Ferraz-Shawmut under the name Basic Power Engineering and Manufacturing. When Littelfuse and Bussmann decided to limit their distribution strategy, OptiFuse saw the opportunity to create a catalog of fuse and fuse holder products. Today, they manufacture and distribute a wide array of products that include: automotive and electronic fuses industrial fuses, resettable PTC type fuses, fuse clips and blocks and panel-mounted, inline, and PCB mounted fuse holders. RSP Supply is a proud distributor of OptiFuse fast-acting fuses.
