Mega Fuses (AMG) — 100A to 500A, Bolt-Down High Current

Mega fuses (AMG), the large bolt-down fuse for protecting the heaviest 12V and 24V circuits — the step up from midi for high-output alternators, large inverters, winches and main battery feeds. Bolt holes clamp the fuse securely to a mega holder or busbar, and the exposed element shows at a glance whether it has blown.
