12V 12 Way Pre-Wired Fuse Relay Box Kit with 4 x 80A 4-Pin Relays

Key features

• PLUG & PLAY READY Pre-wired and ready to install right out of the box. This 12-way fuse and relay module kit includes four heavy-duty 4-pin 80A relays and 12 ATC/ATO blade fuses (10A, 20A, 30A). Fuses can be easily swapped to match your specific accessory power requirements
• SAFE CURRENT LIMITATIONS While the relays are upgraded to a massive 80A rating for handling high inrush currents, the pre-installed 4mm² wire gauge safely sustains a maximum continuous load of 30A per circuit. The total combined current across all circuits must not exceed 128A. Always verify your accessory's operating amperage to prevent overheating. (Note: An unwired version is available for custom heavy-gauge projects)
• DUST & DEBRIS PROTECTION Features a secure top cover that blocks dust and dirt while protecting active circuits from accidental contact. NOTE: This unit handles light splashes but is NOT fully waterproof. For optimal safety, mount it in a dry location—such as the cabin or a protected under-hood area—away from direct rain or submersion
• DUAL CIRCUIT PROTECTION Engineered for maximum electrical safety. The pre-wired 4 relays are connected in series with the fuses to deliver reliable, double overcurrent protection. A highly versatile 12V power management solution perfectly suited for headlights, fog lights, air horns, fuel pumps, cooling fans, LS swaps, and custom 4x4, truck, SUV, or RV builds
• VERIFY MOUNTING CLEARANCE To ensure a seamless installation, please carefully review the product dimensions: 160mm x 80mm x 70mm (6.3" x 3.15" x 2.76"). Confirm your vehicle has adequate clearance—whether under the hood, under the dash, or in the trunk—to accommodate both the box's footprint and the necessary space for bottom wire routing
