Blue Sea 5029 ST Blade Fuse Block 12 Circuits with Cover

The Blue Sea Systems 5029 ST Blade Fuse Block – 12 Circuits with Cover is a professional-grade marine fuse distribution block designed to provide safe, organised, and reliable circuit protection for 12V and 24V DC electrical systems. Featuring 12 individually fused positive circuits and a durable insulating cover, it offers a clean and efficient solution for powering marine electronics and onboard accessories while simplifying electrical installations.

Unlike models with an integrated negative bus, the Blue Sea 5029 is designed for installations that already utilise a separate negative bus bar or grounding system. Its tin-plated copper bus bar and fuse clips deliver outstanding conductivity and corrosion resistance, making it ideal for harsh saltwater environments. The block accepts industry-standard ATO® and ATC® blade fuses, ensuring replacement fuses are readily available throughout New Zealand.

The transparent snap-on cover protects against accidental short circuits while providing storage for spare fuses and clearly labelled circuit identification. Rated for 100 amps total capacity and 30 amps per individual circuit, the Blue Sea 5029 is ideal for distributing power to chartplotters, fish finders, VHF radios, lighting, bilge pumps, refrigeration, USB outlets, stereo systems, and other onboard equipment.

Trusted by marine electricians, boat builders, and commercial operators worldwide, the Blue Sea Systems 5029 delivers long-lasting performance, professional wiring organisation, and dependable electrical protection for vessels operating in demanding New Zealand marine conditions.
