6 Way Fuse Relay Box 12V 40A Automotive Universal Fuse Panel

Ultimate 12V Power Distribution for Your Custom Builds Take control of your vehicle's electrical system with our high-capacity 6-Way Relay and Fuse Box. Designed for DIY enthusiasts, off-roaders, and professional mechanics, this centralized hub eliminates wiring clutter and provides robust protection for your aftermarket accessories, from LED light bars and cooling fans to air horns and water pumps. Dual-Color LED Diagnostics Troubleshooting is no longer a guessing game in the dark. Our advanced PCB board features a dual-color LED monitoring system for each individual circuit: GREEN LED (Relay Status): Confirms the relay coil is successfully engaged and operating normally. (If the light is OFF, it instantly indicates a wiring or coil fault).RED LED (Fuse Warning): Instantly lights up when an ATC fuse is blown, allowing you to pinpoint and replace the dead fuse in seconds. SPDT Switching & Dual Circuit ProtectionThis block is fully loaded with four 4-Pin SPST relays and two 5-Pin SPDT relays. The 5-Pin design enables seamless dual-state switching—perfect for routing power from Daytime Running Lights (NC) to LED Light Bars (NO) via a single switch trigger. Engineered for ultimate safety, these heavy-duty relays feature built-in resistors that actively absorb voltage spikes and transient surges, protecting your vehicle's sensitive ECU and switch panels. Coupled with the quick-acting ATC blade fuses, your circuits benefit from true dual-layer protection against short circuits and electrical fires. Premium High-Temp Construction Constructed with a high-temperature resistant PA66 Nylon top cover and a rugged ABS base, this box is engineered to withstand the extreme heat of intense under-the-hood (engine bay) environments. Installation Warning: This fuse box is NOT waterproof. It MUST be mounted in a high, dry location strictly shielded from direct water spray, deep water crossings, and pressure washers. Fully Loaded & Bonus Spares Included:1x 6-Way Relay & Fuse Box Hub4x 4-Pin SPST Relays2x 5-Pin SPDT Relays6x Pre-installed ATC Fuses (10A, 25A x2, 30A x2, 40A)6x Bonus Spare Fuses (20A x2, 25A x2, 30A x2) securely housed inside the top cover for emergency trail repairs DIY Safety Limit: When customizing your setup, never upgrade any fuse to more than 5 Amps above its factory rating. Always derate your continuous electrical loads by 10-15% to prevent overheating and maximize longevity.

• 【6-WAY WIRING & SPDT CAPABILITY】Upgraded to a high-capacity 6-circuit hub featuring 4x SPST 4-Pin relays and 2x SPDT 5-Pin relays. The 5-Pin design enables seamless dual-state switching—perfect for routing power from Daytime Running Lights (NC) to LED Light Bars (NO) via a single switch trigger. Comes pre-installed with 6 ATC fuses (10A to 40A), plus 6 bonus spare fuses neatly housed inside the top cover
• 【DUAL CIRCUIT PROTECTION】Engineered for ultimate safety. Features built-in resistor relays that actively absorb voltage spikes and transient surges, protecting your vehicle's sensitive ECU and switch panels from electrical damage. Meanwhile, the individual ATC blade fuses instantly cut power during short circuits or overloads to prevent electrical fires
• 【LED INDICATOR LIGHT】Troubleshoot circuit faults instantly by observing the indicator light status. The Relay Status LED shines GREEN to confirm healthy coil engagement (LED OFF indicates a coil fault or wiring issue). Meanwhile, the dedicated Fuse Warning LED shines RED to instantly alert you to a blown fuse, saving you hours of manual testing
• 【PREMIUM FLAME-RETARDANT】Built to handle intense under-the-hood (engine bay) temperatures. Constructed with a high-temp PA66 Nylon top cover and a rugged ABS base. Installation Warning: This fuse box is NOT waterproof. It MUST be mounted in a high, dry location strictly shielded from direct water spray, deep water crossings, and pressure washers
• 【DIY SAFETY LIMITS & COMPATIBILITY】A reliable 12V power management hub for Trucks, UTVs, ATVs, RVs, and Marine watercraft. DIY Safety Limit: When customizing your setup, never upgrade any fuse to more than 5 Amps above its factory rating to maintain safe thermal limits. Pro Tip: Always derate your continuous electrical loads by 10-15% to prevent overheating and maximize longevity
