Maxi Fuses & Holders
Heavy-duty 12V and 24V maxi blade fuses and waterproof inline holders for reliable circuit protection
Reliable Maxi Fuses & Waterproof Inline Holders
Safeguard your off-grid electrical systems with our robust range of maxi blade fuses and waterproof inline fuse holders. Designed specifically for demanding 12V and 24V applications across caravans, RVs, marine vessels, and 4WD canopies, these heavy-duty circuit protection components ensure your electrical wiring remains safe from overcurrent and short-circuit faults. Featuring the highly durable Exotronic lineup, our selection is engineered to deliver uninterrupted performance even in the harshest Australian conditions.
High-Capacity Maxi Blade Fuses
When running medium-to-high current accessories like air compressors, mid-sized inverters, or DC-DC chargers, standard blade fuses often fall short. Our Exotronic maxi fuses step up to handle higher continuous loads, available in a comprehensive range from 20A through to 100A. The oversized blade design offers excellent contact area, reducing resistance and preventing heat build-up under load. This makes them an ideal choice for primary circuit protection on auxiliary battery feeds or heavy-draw 12 volt appliances.
Waterproof Inline Maxi Fuse Holders
A high-quality fuse is only as effective as its holder. Our Exotronic inline maxi fuse holders are constructed to withstand extreme environments, featuring tight-sealing covers that protect against dust, moisture, and water ingress. To ensure long-lasting conductivity and prevent corrosion, these holders are pre-wired with marine-grade tinned copper cable.
Key features of our inline fuse holders include:
- Tinned Copper Wiring: Marine-grade cable resists oxidation, ensuring excellent conductivity and safety in humid or coastal environments.
- Multiple Cable Sizes: Available in 8AWG and 6AWG variants to match your specific current requirements and minimise voltage drop.
- Waterproof Housing: A secure rubberised cap provides a tight seal, making them perfect for engine bays, chassis mounting, and wet marine environments.
- Seamless Integration: Easily splice these inline holders into your existing automotive cables using quality crimps and heat shrink tubing for a professional finish.
Frequently Asked Questions
What size maxi fuse do I need for my 12V system?
The correct fuse size is determined by the continuous current draw of your appliance and the current-carrying capacity of your wire. Your fuse must be rated higher than the normal operating current of your device but lower than the maximum safe current limit of the cable. For example, if your appliance draws 30A, a 40A maxi fuse is typically appropriate, provided the wire is rated to handle well over 40A.
Are these fuse holders suitable for marine applications?
Absolutely. The Exotronic inline fuse holders are built with marine-grade tinned copper wire, which provides superior resistance to saltwater corrosion compared to standard bare copper. Combined with the waterproof sealing cap, they are exceptionally well-suited for boats, yachts, and coastal off-grid installations.
What is the difference between the 8AWG and 6AWG holders?
The AWG rating refers to the thickness of the cable pre-wired into the holder. A 6AWG wire is thicker than an 8AWG wire, meaning it can safely carry more current over a given distance with less voltage drop. For higher amperage fuses like 80A or 100A, the 6AWG holder is highly recommended to maintain system efficiency and safety.
