RVBOATPAT 12V 6-Way Pre-Wired Relay Fuse Box — 6×40A Relays & 12 ATC/ATO Fuses, Splash-Resistant

RVBOATPAT 12V 6-way pre-wired relay fuse box combines six 40A relays with twelve ATC/ATO blade fuses in a splash-resistant enclosure for organized, reliable circuit protection in cars, trucks, RVs and boats.

This compact relay and fuse panel is designed to centralize power switching and circuit protection for auxiliary accessories. It arrives pre-wired with color-coded leads and a protective housing to accelerate installation, reduce wiring clutter, and help shield connections from dust and light water exposure. With a mix of common fuse ratings included, the kit supports a variety of accessory loads without hunting for extra parts.

How does this relay fuse box simplify wiring on my vehicle or boat?

The unit comes pre-wired so you don’t have to splice multiple relay and fuse leads during setup. Color-coded cables and labeled positions make routing and troubleshooting faster, and the integrated relays reduce the number of stand-alone components you need to mount.

• Six 4-pin 40A relays already installed for high-current switching
• Color-coded wires for quick identification and cleaner installs
• Centralizes multiple accessory circuits in one compact module
• Reduces separate relay/fuse mounting and wiring complexity

What fuses and relays are included, and what loads do they cover?

The kit supplies twelve ATC/ATO blade fuses spanning common ratings and six 40A automotive relays. That combination supports small- to medium-current accessories like lights, pumps, horns and auxiliary outlets when paired with the appropriate fuse.

• Fuses: two each of 10A, 20A, 25A, 30A, 35A and 40A for flexible protection
• Relays: six 4-pin 40A relays suitable for switching motors, lighting and fans
• Supports multiple accessory circuits without additional fuse holder purchases
• Ideal for devices drawing moderate continuous or intermittent current

Is the enclosure durable and safe for marine or outdoor use?

The enclosure provides basic insulation and splash resistance to keep dust and light moisture out of the relay and fuse compartments. It’s not a fully submersible box, but the protective case and tidy internal layout reduce corrosion risk and accidental shorting in exposed installations.

• Insulated housing to minimize dust ingress and splash exposure
• Pre-wired internal layout lowers chances of loose connections
• Screw-mountable design for secure fastening to vehicle or craft surfaces
• Recommended placement: protected cabin or sheltered cockpit area for best longevity

How do I use this panel with my accessories—what’s the installation approach?

Mount the box in a convenient protected location, route power and accessory leads to the appropriate terminals, and select the correct fuse for each circuit. Use the relays to switch high-current loads from a low-current control source such as a switch, ignition feed or controller.

• Mount using provided screw holes in a sheltered area
• Connect battery positive/negative to the main power inputs as instructed
• Fit each accessory to a relay output and insert the matching fuse
• Use control switches or ignition feeds to trigger relays safely

Who is this for: This pre-wired relay and fuse box suits DIY installers, professional mechanics, and marine technicians who need a tidy, ready-to-install power distribution solution for auxiliary circuits. It’s useful for anyone adding lighting, pumps, horns, winches or other accessories that require reliable switching and standardized blade-fuse protection without the hassle of assembling individual relays and holders.
