175A AMI / MIDI High-Current Bolt-Down Fuse
Heavy-Duty 175 Amp Circuit Protection for Inverters & Battery Links
Engineered to protect high-draw DC circuits from severe overloads and short circuits, the 175A AMI / MIDI Bolt-Down Fuse provides heavy-duty circuit protection in a compact footprint. Designed specifically for high-power dual-battery lines, pure sine wave inverters, electric winches, and main battery distribution posts, this fuse handles massive current flows while remaining immune to false trips from brief startup spikes.
Featuring tin-plated copper contacts, it offers minimal voltage drop and superior corrosion resistance. The M5 bolt-down eyelet design ensures a vibration-proof, high-torque electrical connection—essential for 4WD touring, marine engine bays, and off-grid power systems.
Key Features
-
175 Amp High-Capacity Rating: Ideal for protecting heavy-gauge main battery feeds, large DC-DC chargers, and medium-to-large inverters.
-
Slow-Blow Surge Tolerance: Time-delay characteristics withstand short-duration high-inrush currents during inductive load power-up.
-
Vibration-Proof M5 Bolt-Down Design: Mounts securely to M5 studs to eliminate loose friction connections, arcing, and heat buildup off-road.
-
Tin-Plated Copper Blades: Maximizes conductivity while protecting terminals from oxidation in harsh marine and automotive environments.
-
Clear Amperage Markings: Stamped 175A rating and color coding allow rapid visual verification during routine maintenance or troubleshooting.
