You're pushing 300A through a battery or alternator feed and the protection you've got is either undersized or blowing on every startup surge. This slow-blow MEGA bolt-down fuse handles that load without nuisance-breaking.
Patented high-current protection, the same spec OEM on Ford, GM and Chrysler vehicles. Rated to a maximum of 32VDC. Fits the SF1980 High Current MEGA Bolt Down Fuse Holder directly — no adapters, no workarounds.
Built for the heaviest battery connections, alternator feeds, and thick-gauge cable runs where a standard fuse simply can't keep up. Part of a seven-rating family (80A to 300A), so if your build scales down later, you're on the same holder.
Add it to cart and stop running an unprotected 300A circuit that's one short from a serious fault
