Key features
- Plug & Play Pre-Wired Design Ready to use right out of the box. This 12V distribution block includes two heavy-duty 4-Pin SPST 40A (JD1912) relays and six ATC/ATO blade fuses (10A, 15A, 30A). The color-coded, pre-wired harnesses eliminate tedious crimping and wiring errors, ensuring a clean and professional DIY setup
- Safe Current Limitations While the relays are rated for 40A, the system's actual limit depends on the pre-installed 2.5mm² wire gauge. It safely sustains a 25A maximum continuous load per circuit, and the total combined current across all circuits must not exceed 64A. Always verify your accessory's operating amperage before connecting to prevent overheating or blown fuses. (An unwired version is available for custom heavy-gauge projects)
- Smart Circuit Protection Engineered for ultimate electrical safety. Two of the six fuse slots are wired in series with the relays, providing double overcurrent protection for your primary high-draw accessories. A versatile solution perfectly suited for custom wiring on 4x4s, trucks, SUVs, and RV trailers
- Dustproof Enclosure Features a secure top cover that effectively blocks dust, dirt, and debris while protecting the circuits from accidental contact. IMPORTANT NOTE: This unit is strictly dustproof and NOT WATERPROOF. Please mount it in a dry, protected location (such as the cabin or trunk); do not expose it to direct rain, water splashes, or submersion
- Verify Mounting Clearance To ensure a perfect fit, please note the fuse box dimensions are 4.02″ x 2.8″ x 3.15″. Ensure your vehicle has adequate clearance—whether under the hood, under the dash, or in the trunk—to accommodate the box's size and the necessary space for the bottom wire exits
