100A AMI / MIDI High-Current Bolt-Down Fuse

Dependable 100 Amp Circuit Protection for DC-DC Chargers & Inverters

Engineered to protect high-current DC power lines against dangerous overloads and short circuits, the 100A AMI / MIDI Bolt-Down Fuse delivers robust protection in a compact footprint. Sized for 600W–800W pure sine wave inverters, high-output 50A DC-DC battery chargers, dual-battery auxiliary feeds, and main fuse blocks, this 100 Amp fuse reliably handles continuous heavy loads while preventing nuisance trips.

Featuring tin-plated copper alloy contact blades, it maintains high conductivity with minimal voltage drop. The M5 bolt-down eyelet design guarantees a solid, vibration-resistant connection that will not loosen, arc, or overheat—making it an essential component for 4WD touring, caravan, camper, and marine electrical systems.

Key Features

• 100 Amp Continuous Protection: Perfectly rated for protecting 50A+ DC-DC battery chargers, 600W–800W inverters, and primary auxiliary battery lines.

• Slow-Blow Time-Delay Element: Engineered to tolerate short startup current spikes (inrush current) without false blowing when powering up equipment.

• Vibration-Proof M5 Bolt-Down Mount: Secures firmly to M5 studs to eliminate loose contacts and resistive heat buildup off-road or at sea.

• Corrosion-Resistant Terminals: Tin-plated copper blades deliver superior conductivity and long-term protection against oxidation and humidity.

• Clear Visual Inspection: Stamped 100A rating and transparent housing window allow for instant visual diagnostic checks inside fuse holders.
