DAIERTEK 12V Relay & Fuse Box — 10-Way Relay with 10 ATC Blade Fuses, Dustproof Pre-Wired Panel

This compact, ready-to-install relay and fuse block groups multiple circuits into a single enclosure so you can tidy up wiring, add accessories, and protect electrical loads without custom harnessing. Designed for automotive and marine 12V systems, the module arrives pre-wired with color-coded leads and heavy-duty 12 AWG feed wiring for higher-current devices. A clear top and bottom cover keeps dust and stray wires away from contacts while making inspection and fuse replacement fast.

How does the DA IERTEK relay box simplify wiring installations?

The unit ships pre-wired so you avoid mapping and soldering individual relays and fuse holders. Color-coded wires match relay sockets and fuse locations, reducing error and installation time for aftermarket lights, horns, pumps, and other accessories.

• Pre-wired relay sockets (10 total) with color-coded leads for straightforward connections.
• 12 AWG main feed wiring for reliable power delivery to high-draw circuits.
• 15 total fuse positions, 10 integrated with relays and 5 additional spare/aux positions.
• Includes 15 ATC/ATO blade fuses so basic installations can start immediately.

What protection features keep my circuits safe?

The block combines fuses and relays so each accessory gets both overcurrent protection and switched control. Fuses prevent excessive current flow, while relays isolate switches from high currents and reduce voltage drops to downstream devices.

• Dual protection: individual blade fuses plus relay-controlled switching for each primary circuit.
• Dustproof cover prevents debris and accidental shorting of terminals.
• Clearly labeled fuse positions and relay colors for quick troubleshooting.
• Durable plastic housing resists vibration and corrosion typical in vehicle environments.

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

The panel includes 10 relays and 15 ATC/ATO blade fuses arranged to serve both switched and auxiliary circuits. Eight relays use a 4-pin footprint and two use a 5-pin footprint, giving flexibility for common and latching relay uses.

• 10 relay slots: eight 4-pin relays (various colors) plus two 5-pin relays (red and purple).
• 15 blade fuse positions: 10 paired with relays, 5 spare positions for extra circuits.
• Color-coded relay housings and labeled fuse slots for easier identification.
• Suitable for standard ATC/ATO fuses you can swap to match circuit amperage.

Who is this for? Technicians, DIY mechanics, marine electricians and vehicle customizers who want a neat, reliable way to add and protect multiple 12V accessories will benefit most from this DA IERTEK relay and fuse box. It’s ideal when you need a compact solution that reduces wiring complexity, improves serviceability, and offers a dust-resistant enclosure for under-dash, engine-bay-adjacent, or bilge installations. If you prefer a pre-assembled, color-coded panel that supports higher current loads and keeps circuits clearly labeled, this module fits those needs without requiring a custom harness or extensive electrical expertise.
