Baintech BTFB12R 12 Way Fuse Block with Clear Poly-Carbonate Cover

Organized circuit protection for 4WD and marine electrical systems

The Baintech BTFB12R is a 12-way fuse block engineered to consolidate and protect multiple electrical circuits in 4WD, caravan, and marine installations. This fuse distribution panel accepts standard ATO and ATC blade fuses, providing up to 30A protection per individual circuit with a 100A maximum total capacity.

The clear poly-carbonate cover meets ABYC/USCG insulation requirements while allowing visual fuse inspection, and the common positive/negative bus bars simplify wiring by eliminating multiple connection points. Built-in spare fuse holders and included circuit labels make this an essential component for organized auxiliary power systems in touring vehicles, camper trailers, and boat electrical installations.

Features & Benefits

12 Individual Fuse Circuits — Protect and organize up to 12 separate appliances or accessories from a single distribution point, ideal for complex 4WD setups running fridges, lights, pumps, inverters, and communication equipment without tangled wiring.

100A Total Capacity with 30A Per Circuit — Handle substantial total loads while protecting individual circuits appropriately, perfect for caravan installations where multiple high-draw appliances operate simultaneously without overloading any single fuse position.

Common Positive and Negative Bus Bars — Simplify installation by connecting power once to shared terminals rather than running individual wires to each circuit, reducing connection points and installation time in tight engine bay or under-seat locations.

ATO/ATC Blade Fuse Compatibility — Accept widely available standard and mini blade fuses found at automotive stores across Australia, ensuring you can source replacements anywhere during remote touring or marine expeditions.

Clear Poly-Carbonate Cover — Inspect fuse status visually without removing the cover while meeting ABYC/USCG insulation safety standards, essential for marine applications and vehicles exposed to salt spray, dust, and moisture.

Reinforced Poly-Carbonate Base — Withstand vibration and impact in off-road environments, providing durable mounting for auxiliary battery systems subject to corrugations, rough tracks, and marine conditions.

Integrated Spare Fuse Storage — Keep two spare fuses secured within the block for emergency replacements on remote tracks or offshore, eliminating searches through toolboxes when a fuse fails.

Circuit Labeling System — Identify each circuit clearly with included labels, simplifying troubleshooting and preventing confusion when multiple users access the electrical system in shared vehicles or charter boats.

Frequently Asked Questions

What size fuses does this block accept?

The BTFB12R accepts ATO and ATC standard blade fuses as well as mini blade fuses, all of which are fast-acting types commonly available at automotive retailers.

Can I run 12 circuits at 30A simultaneously?

No, while each individual circuit supports up to 30A, the total combined load across all circuits must not exceed 100A to prevent overloading the bus bars.

Is this suitable for marine environments?

Yes, the poly-carbonate cover meets ABYC/USCG insulation requirements and the reinforced construction withstands marine conditions, though additional weatherproofing of connections is recommended.

How do I connect power to this fuse block?

Connect your positive power source to the common positive bus bar and ground to the common negative bus bar, then wire individual circuits from each fused outlet to your appliances.

Does this come with fuses included?

Not specified; purchase appropriate ATO or ATC blade fuses separately based on the current requirements of each circuit you're protecting.
