This heavy duty inline fuse holder 12V is built around 12 AWG wire for lower voltage drop and better protection across demanding automotive installs. Designed as an automotive fuse holder for standard ATC/ATO blade fuses, it accepts 1–30 A ratings so you can protect radios, dash cams, lighting, compressors and other 12V accessories with confidence. The compact body (approx. 41 × 35 × 15 mm) and tight, water-resistant rubber cap help keep dust and spray away from the contacts, making it a reliable waterproof fuse holder for cars, 4WDs, vans, trucks, caravans and boats. Each unit ships with a 30 cm loop so you can cut the in line fuse to your required length for neat routing and tidy looms, and it uses robust fuse connectors for a clean, secure splice.

As an inline car fuse holder, it fits standard blade fuse dimensions (about 19.1 mm long × 18.5 mm high × 5.1 mm wide) and works as a dc fuse holder or blade fuse holder in general 12V systems. Use it anywhere a car inline fuse or automotive inline fuse adds safety between your accessory and the battery or distribution block. The snug cap and durable housing make this inline blade fuse holder 12V suitable for engine bays and marine compartments where occasional splash or dust is expected. It functions as a practical car fuse adapter / fuse adapter for single-circuit additions, while remaining compact enough to tuck behind trim.

This kit also includes two 25 A blade fuses so you can get up and running quickly with your most common loads, and four heat-shrink butt connectors made with thick barrels and high-tensile, heat-shrink tubing to deliver a strong crimp every time—safer, easier connections with a professional finish.
