Circuit Breakers

Automotive circuit breakers provide reusable, resetting overcurrent and short circuit protection. Littelfuse proudly offers a full range of these alternatives to automotive fuses for commercial vehicles. We deliver OEM and aftermarket blade-style, box-style, glass fuse, and hi amp circuit breakers under trusted brand names such as ATO^® and MINI^®. Our automotive circuit breakers fit into existing fuse blocks and fuse clips, and our aftermarket bladed circuit breakers feature scored terminals. This makes it easier to trim the blades if doing so is necessary to ensure secure installation.
