A weatherproof inline blade fuse holder that adds circuit protection to any 12V or 24V accessory feed and keeps the fuse itself sealed against moisture, dust and engine-bay grime. Splices into aux socket runs, driving light circuits, air compressor feeds, radio backbones and fridge power leads. Fits engine bays, 4WD canopies, boat helms, caravan under-bench wiring and any exposed run.

A snap-seal cap covers the fuse itself. Pre-attached 6mm² automotive-grade cable runs off each side ready to splice into your circuit. That gauge sits well above what a 30A fuse needs, so the cable itself never becomes the bottleneck on longer runs. Takes standard blade fuses, also called ATC, ATO or ATS (same fuse, different names), from 1A to 30A.

Rate the fuse for the smallest current the downstream cable can safely carry, not for the load itself. Never step up to a bigger fuse to stop nuisance blowing, that's the sign of a fault worth diagnosing, not overriding.

⚠ Important: the weatherproof seal is on the fuse itself. If you splice the pre-attached cable to your circuit with bare crimp barrels, water gets in at the joints and the weatherproof rating is defeated at those points. Finish the splices with adhesive-lined dual-wall heat shrink to keep the whole install waterproof end-to-end.

Q: What's the difference between ATC, ATO and ATS blade fuses?
They're the same fuse. Standard blade fuses (the flat colour-coded ones, red 10A, blue 15A, yellow 20A, clear 25A, green 30A) are known by three interchangeable names: ATC (Automotive Thermoplastic Case), ATO (Automotive Technology, Original) and ATS. Any of those three names on the packet fits this holder.

Q: Is this waterproof or weatherproof, what's the difference?
Weatherproof means the sealed cap keeps rain, spray, mud and dust out of the fuse compartment under normal driving and moderate marine conditions. It's not rated for full submersion (that would be IP68 waterproof). For 99% of automotive installs, engine bay, canopy, boat, caravan, weatherproof is what you want. The one gap: the seal is on the fuse itself, so the splice joints where you connect the cable to your circuit also need weatherproofing. See the note below.

Q: Does the holder come with a fuse?
No. Fuses are sold separately so you can pick the amperage that suits your circuit, a 5A LED strip needs a very different fuse than a 25A air compressor. Our 120-piece assorted standard blade kit covers every common amperage if you don't already have one on hand.

Q: Do I really need heat shrink on the splice for it to be weatherproof?
Yes if you want the install to actually survive weather. The holder seals against water at the fuse. But the two ends of the pre-attached cable have to join to your circuit somewhere, usually with crimp barrels. Bare crimp barrels wick water into the copper strands, which corrodes the joint and eventually breaks the circuit or drops voltage. Adhesive-lined dual-wall heat shrink shrinks down over the crimp and melts a waterproof glue lining as it heats, sealing the joint properly.

Q: What if my vehicle uses mini or micro 2 blade fuses instead?
Standard blade won't fit those slots. Modern Japanese and European vehicles often use mini blade fuses (smaller, half-height) or micro 2 fuses (smallest, tall thin profile). Check what type your vehicle uses before ordering; inline holders in mini and micro 2 sizes are available in our range as separate products.

Q: Why is the cable 6mm² if the fuse only goes to 30A?
Because 6mm² (roughly 10 AWG) is genuinely over-spec'd for 30A and that's a good thing. Cheaper inline holders ship with 3mm² or 4mm² cable which is fine at 15A but starts dropping voltage and warming up above 20A on longer runs. The heavier cable means the cable itself is never the bottleneck, the fuse blows before the cable stresses.

Q: Can I use this on a 24V system?
Yes. Standard blade fuses are rated to 32V DC, and the holder and cable are automotive DC spec, works fine on 12V, 24V and any DC system up to 32V.
