30A AMI / MIDI High-Current Bolt-Down Fuse

Dependable 30 Amp Circuit Protection for DC-DC Chargers & Auxiliary Circuits

Engineered to protect low-to-medium current DC power lines against overloads and short circuits, the 30A AMI / MIDI Bolt-Down Fuse provides compact, heavy-duty circuit protection. Sized specifically for 10A–15A DC-DC battery chargers, small 200W–300W inverters, fridge power circuits, and auxiliary distribution sub-lines, this 30 Amp fuse reliably handles continuous loads while preventing false trips.

Featuring tin-plated copper alloy contact blades, it maintains high electrical conductivity with minimal voltage drop across your circuit. The M5 bolt-down eyelet design guarantees a rock-solid, vibration-proof connection that will not loosen, arc, or overheat under demanding 4WD, caravan, camper trailer, and marine operating conditions.

Key Features

• 30 Amp Continuous Protection: Rated specifically for protecting 10A/15A DC-DC battery chargers, portable fridges, LED light bars, and secondary accessory sub-feeds.

• Slow-Blow Time-Delay Element: Engineered to tolerate brief startup current spikes (inrush current) without false blowing when initiating loads.

• Vibration-Proof M5 Bolt-Down Mounting: Secures firmly onto M5 studs to eliminate loose contacts and resistive heat buildup caused by rough off-road terrain or engine vibration.

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

• Clear Visual Inspection: Stamped 30A rating and transparent housing window allow for instant visual diagnostic checks inside fuse holders.
