Blue Sea Systems ST Blade Fuse Block

The Blue Sea Systems ST Blade Fuse Blocks provide a compact, professional solution for consolidating branch circuits and replacing multiple in-line fuse holders. Designed for 12V and 24V DC systems up to 32V DC, these marine-grade fuse blocks simplify wiring while providing safe, organised circuit protection.

Constructed with tin-plated copper buses and fuse clips, the ST Blade Fuse Blocks deliver excellent conductivity and corrosion resistance in demanding marine environments. They accept standard ATO® and ATC® blade fuses (sold separately) and support both ring and snap fork terminals for quick, secure installation.

Models are available with either positive bus only or positive and negative buses, in 6-way or 12-way configurations. Versions supplied with a cover feature an easy-open push-button latch, storage for two spare fuses, recessed label locations and 20 write-on circuit labels for clear circuit identification. The cover also satisfies ABYC/USCG insulation requirements.
