Features & Benefits
250A High-Current Capacity: Handles demanding loads like inverters, winches, and high-output alternators without voltage drop or overheating—essential for modern 4WD dual battery systems and commercial vehicle fitouts.
Stainless Steel Construction: Unlike cheaper brass or plated terminals, stainless studs resist corrosion in coastal environments, under-bonnet heat, and dusty outback conditions, ensuring long-term reliability across Australia's varied climates.
Extreme Temperature Rated: Proven performance from -40°C to +120°C means this holder won't crack in desert heat or fail in alpine cold, making it the choice for touring rigs and remote work vehicles that face temperature extremes.
30mm Mounting Centres: Standard SF30 format with precise 30mm spacing allows secure installation using the optional ACX6513 bracket or custom mounting solutions, giving installers flexibility in tight engine bays or battery boxes.
Trade-Ready Bulk Pack: 50 units per box reduce per-unit costs for workshops, auto electricians, and fleet maintenance teams who install multiple systems—ideal for standardising protection across a vehicle fleet or keeping workshop stock levels high.

Frequently Asked Questions
What size Midi fuse does this holder accept?
This holder is designed for SF30 Midi fuses with 30mm mounting centres, commonly available in ratings from 30A to 250A.
Can I mount this holder without the bracket?
Yes, the stainless studs can be bolted directly to a suitable surface, though the ACX6513 bracket provides neater installation and strain relief.
Is this suitable for 24V truck systems?
Absolutely—the 1-32V rating covers both 12V passenger vehicles and 24V commercial/heavy vehicle electrical systems without derating.
Will this handle starter motor or alternator circuits?
Yes, the 250A continuous rating suits high-current alternator feeds, though starter circuits may require higher surge-rated protection depending on engine size.
