150A AMI / MIDI High-Current Bolt-Down Fuse
Heavy-Duty 150 Amp Circuit Protection for Inverters & High-Output Chargers
Engineered to protect medium-to-high-draw DC electrical circuits from short circuits and severe current overloads, the 150A AMI / MIDI Bolt-Down Fuse delivers robust protection in a space-saving footprint. Ideal for 1000W to 1200W pure sine wave inverters, high-amp BCDC chargers, auxiliary battery interconnect lines, and heavy-duty 12V/24V accessory distribution blocks.
Featuring tin-plated copper alloy contact blades, this fuse ensures minimal voltage drop and high corrosion resistance. The M5 bolt-down design guarantees a tight, vibration-resistant electrical connection that won't loosen or arc under rough off-road, caravan, or marine operating conditions.
Key Features
-
150 Amp Continuous Capacity: Sized specifically for protecting high-output 12V and 24V DC circuits, heavy power feeds, and medium-capacity inverters.
-
Slow-Blow Time-Delay Element: Built to tolerate momentary high-inrush startup currents without nuisance blowing when powering up inductive loads.
-
Vibration-Proof M5 Bolt-Down Mounting: Secures firmly via M5 studs/bolts to eliminate high-resistance loose contacts caused by severe engine or vehicle vibration.
-
Tin-Plated Copper Blades: Delivers superior electrical conductivity while resisting oxidation and salt-air corrosion in marine and automotive applications.
-
Clear Visual Rating & Inspection: Stamped 150A rating with a clear viewing window allows for rapid diagnostic verification.
