12VS 6-Way Fused Relay Distribution Box | Unwired Standard Edition

Part Number: RELFUSE6

Streamline Your Power. Secure Your Ride.

Tired of messy wiring, unreliable connections, and the headache of adding new accessories to your vehicle? The 12VS 6-Way Fused Relay Distribution Box is the ultimate solution for centralized, heavy-duty automotive power management.

Designed for 12V professionals and serious DIYers who demand superior electrical organization, this unwired standard block gives you 100% control over your wiring architecture. Unlike pre-wired alternatives, the unwired edition allows you to run independent, heavy-gauge supply lines directly to each circuit—making it the ideal choice for demanding, high-draw setups.


What’s In The Box:

  • 6 x 12V 40A 4-Pin Relays
  • 6 x ATC/ATO Blade Fuses (Provides dedicated protection for the 6 relay circuits)
  • Full Professional Terminal Kit: Premium uninsulated open-barrel female spade terminals for both the relay sockets and the blade fuse connections, allowing you to achieve professional, gas-tight F-crimps across the entire module.

Key Features & Benefits:

  • Uncompromising Power Delivery: Built with heavy-duty, independent terminal slots. Because it is completely unwired, you aren't restricted by shared common feeds—allowing you to maximize the full continuous capacity of the included 40A relays.
  • Centralized Distribution: Consolidate your accessory wiring, fuses, and switching relays into one neat, heat-resistant housing. Say goodbye to inline fuse holders and spaghetti wiring under the hood.
  • 6-Way Fuse Protection: Features six independent ATO/ATC blade fuse slots, giving each of your six relays its own dedicated, protected power pathway. Isolate faults immediately without knocking out your entire system.
  • Rugged Construction: Engineered to withstand harsh Australian engine bay environments and cabin heat, ensuring vibrating connections stay secure.
  • Compact Footprint: Delivers powerful six-relay management in a highly compact design, making it perfect for tight mounting locations in modern 4WDs, canopy builds, boats, and caravans.

Pro-Installer Technical Note: High-Amp Wiring and 8 B&S Capacity

The RELFUSE6 includes heavy-duty, uninsulated open-barrel spade terminals. Under standard specifications, these open-barrel terminals are designed to comfortably accept up to 6mm auto cable (4.5mm² to 5–6mm² / 10 AWG).

If your installation requires running 8 B&S cable (7.71mm²) over long distances to eliminate voltage drop (e.g., for heavy-duty air compressors or large driving lights), it is physically possible to fit the strands into these uninsulated terminals if you keep the copper strands perfectly straight and untwisted. If executing this layout, you must strictly observe the following safety rules:

  • DO NOT shave or 'haircut' the outer copper strands of the 8 B&S wire to make it fit. Trimming strands reduces the cable's carrying capacity and creates a high-resistance hot spot.
  • DO use a professional open-barrel (F-crimp) ratcheting tool. Standard pliers or basic hand-squeezers cannot supply the extreme crushing force required to roll the terminal "wings" tightly over a dense, fully packed 8 B&S copper core.
  • DO finish the connection with a short length of quality adhesive-lined heat shrink to seal and strain-relief the joint.
  • Alternative Option: Run your heavy 8 B&S main feed to a solid distribution point close to the box, and transition to a short, highly flexible tail of 6mm automotive cable for the final connection to the relay terminal block.

Why Choose the 12VS Unwired Range?

  • Maximum Electrical Safety: Protect your valuable electronics and isolate short circuits instantly.
  • Simplified Troubleshooting: Clean layout and independent fusing let you pinpoint issues in seconds.
  • Future-Proof Design: Add or modify your auxiliary setup later without ripping out your entire electrical system.

Don't let disorganized wiring hold you back. Upgrade to the 12VS RELFUSE6 today and experience the peace of mind that comes with a perfectly engineered, safely protected 12-volt system.


Looking for an easier install? If your power demands are lower (such as camp lights, fridges, or water pumps) and you want a faster, plug-and-play setup, check out our 12VS Pre-Wired Relay Distribution Modules featuring integrated common-feed piggyback wiring.
