DAIERTEK 12V 10-Way Relay & 10-Way ATC/ATO Fuse Box — Pre-Wired, Dustproof, 12 AWG Power

The DAIERTEK 12V relay and fuse box is a pre-wired, dustproof 10-way relay block with a 10-way ATC/ATO blade fuse panel that organizes and protects 12V electrical circuits in cars, trucks, and boats.

This compact relay and fuse assembly combines relays and blade fuses in one neat housing to simplify installations and improve circuit safety. It arrives pre-wired with color-coded leads and heavy-duty 12 AWG power wiring for high-current circuits, plus removable top and bottom covers to keep dust and loose wires away from live terminals. The unit supports up to 15 blade fuses and 10 plug-in relays (eight 4-pin and two 5-pin), giving flexible protection for lighting, pumps, motors, and other 12V accessories.

How does this relay box simplify vehicle wiring?

DAIERTEK’s relay block groups relays and ATC/ATO fuses in a single chassis so you can centralize load switching and circuit protection. Pre-wired, color-coded harnesses mean less time spinning solder and tracing wires, while the heavy 12 AWG feed handles higher currents safely.

• Pre-wired relays and fuses for quick installation
• Color-coded wiring for easier identification
• 12 AWG main power leads for high-current reliability
• 15 fuse slots with 10 relay-associated fuses available

What level of protection and safety does it provide?

The unit uses a dual layer of protection: blade fuses protect individual circuits from overloads, and relays isolate control switches from high-current lines. Dustproof covers reduce contamination and accidental shorts, and dedicated fuse slots let you choose the correct fuse rating for each accessory.

• Dual-protection: relays plus fuses for safer circuits
• Removable top and bottom covers block dust and debris
• Selectable ATC/ATO fuses tailored to each load
• Pre-wired terminals limit exposed connections

Which relays and fuses are included and how are they arranged?

The panel includes 15 ATC/ATO blade fuse slots and 10 relay positions. Eight relay sockets accept 4-pin relays (color-coded yellow, green, white, orange, blue, brown, gray, yellow-green) and two accept 5-pin relays (red and purple), making it easy to match relay function to wiring needs.

• 10 relay sockets: 8 four-pin, 2 five-pin
• 15 fuse slots with included ATC/ATO fuses
• Color-coded relays for quick identification and troubleshooting
• Spare fuse slots for future accessory expansion

Can I use this on boats and off-road vehicles?

Yes — the DAIERTEK relay and fuse box is built for 12V mobile installations like autos, trucks, marine craft, and off-road rigs. Dustproof covers and compact mounting make it suitable for engine bays, cabins, or enclosed compartments where wiring needs to stay tidy and protected.

• Designed for 12V automotive, marine, and off-road systems
• Compact footprint for tight mounting locations
• Dustproof covers improve reliability in dirty environments
• Pre-wired harness reduces installation time on-site

Who is this for: This relay and fuse panel is aimed at vehicle owners, installers, and DIYers who need an organized, reliable way to manage multiple 12V accessories—lights, horns, pumps, fans, and more—without rewiring each circuit individually. If you want a pre-wired solution that reduces installation time, improves circuit protection, and keeps wiring neat in cars, trucks, boats, or off-road vehicles, the DAIERTEK 12V relay box is a practical choice.
