Nilight 6-Pack 12AWG Inline Fuse Holders with Assorted ATC/ATO Fuses – Waterproof, Locking Cover

Nilight’s 6-piece 12AWG inline fuse holder kit provides waterproof protection for ATC/ATO blade fuses, ready to safeguard automotive and marine circuits.

This compact kit bundles six heavy-duty inline fuse holders with a selection of blade fuses so you can protect multiple circuits quickly and cleanly. Each holder uses 12 AWG tin-plated copper conductors and a locking weatherproof cover with a silicone gasket to resist moisture and dust. The soft red pigtail wire and 22.8 cm length simplify routing and connection in cars, trucks, boats, and other 12V systems.

How does this inline fuse holder improve electrical safety on vehicles?

The Nilight fuse holder creates a convenient, replaceable fuse point inline with your power lead so a single fault can disconnect a circuit without damaging wiring or devices. Its ATC/ATO compatibility accepts a range of amp ratings for customized protection.

• Accepts standard ATC/ATO blade fuses from 1A to 30A for tailored circuit protection.
• 12 AWG tin-plated copper wiring reduces oxidation and maintains conductivity.
• Locking weatherproof cover with silicone gasket prevents moisture intrusion.
• Included assortment of 20A, 30A and 40A fuses lets you outfit multiple circuits immediately.

Are these holders suitable for marine and harsh outdoor use?

Yes. The design focuses on water resistance and durability so the holders remain functional in damp or dirty environments. While not a guaranteed protection against prolonged submersion, the tight-fitting cover and gasket protect against spray, rain, and splashes common in marine and outdoor settings.

• Silicone sealing gasket for moisture and dust resistance.
• Locking cover keeps blade fuse secure during vibration and movement.
• Tin-plated copper wire resists corrosion in challenging conditions.
• Mounting tab lets you fix the holder in sheltered locations for extra protection.

How easy is installation and what wiring options does it support?

Installation is straightforward: strip the soft silicone-insulated pigtail, attach to terminals or connectors, and snap the blade fuse into the holder. The 22.8 cm (approx. 9 in) lead provides room to route and connect without splicing in most automotive and marine applications.

• Soft red pigtail wire simplifies stripping and termination.
• 22.8 cm lead length fits common installation scenarios without extra wiring.
• Direct plug-in blade fuse—no cutting required for mounting the fuse itself.
• Mounting tab enables screw or bolt attachment for stable placement.

Which fuses are included and can I replace them with other ratings?

The kit ships with an assortment of blade fuses so you can protect different circuits right away. You may replace the supplied fuses with any correctly sized ATC/ATO blade fuse that matches your circuit’s ampacity and application requirements.

• 6 x inline fuse holders included in the kit for multi-circuit use.
• 6 x 20A, 6 x 30A, and 6 x 40A blade fuses supplied for immediate use.
• Compatible with standard ATC/ATO blade fuses ranging commonly from 1A to 30A (verify fuse selection for your circuit).
• Holders accept straightforward fuse swaps without tools for maintenance.

Who is this for? This Nilight kit fits DIYers, installers, and vehicle owners who need reliable, replaceable protection for multiple 12V circuits—ideal for automotive accessories, auxiliary lighting, marine electronics, and small power accessories. If you want a compact, weather-resistant inline fuse solution with easy installation and a ready supply of blade fuses, this kit provides the components needed to set up and protect several circuits quickly.
