About this item

• [Pre-wired & Ready to Use]:This 12V relay box comes pre-wired with 4mm² (approx. 11AWG) cables for power and output, saving you half the wiring work. Fuses can be swapped in place easily. Perfect for DIYers who want a faster, cleaner installation
• [Compact & Organized Design]:Holds 2 relays and 6 ATC/ATO blade fuses in one box. Keeps your vehicle’s electrical system neat, reduces loose wires, and makes troubleshooting much easier
• [80A Relay – Wire Rating Clarification]:Includes two 4-pin 80A JD1912 relays (contact rating). Important: The pre-wired 4mm² leads are rated for 30A continuous current – suitable for most lights, fans, pumps, and accessories under 30A per circuit. The 80A relay capacity provides a safety margin for inrush current, not for continuous 80A load. Please confirm your device current before purchase
• [High-Current Fuse Kit – Read Before Use]:Comes with 8 x 40A and 4 x 50A ATC/ATO fuses. ⚠️ Warning: These fuses are rated higher than the pre-wired 4mm² wire (30A). For proper circuit protection, replace them with fuses at or below 30A (e.g., 20A, 25A, 30A) based on your load. Using 40A/50A fuses may risk wire overheating before the fuse blows. We supply these as spare high-amp fuses for other applications
• [Dust-resistant Installation & Application]:Top and bottom covers block dust entry. Screw-mount design for secure placement in engine bays, cabins, or dry compartments. Suitable for cars, trucks, Jeeps, RVs, tractors – not for submersion or marine use. Not waterproof
