Blue Sea Systems ST Blade 6 Independent Circuit Fuse Block

The Blue Sea Systems ST Blade Fuse Blocks provide a compact, professional solution for organising and protecting independent branch circuits in marine, automotive and RV electrical systems. Designed for 12V and 24V systems up to 32V DC, they eliminate the clutter of multiple in-line fuse holders while providing safe, reliable circuit protection.

Featuring six independent fused circuits, these fuse blocks accept standard ATO® and ATC® blade fuses (sold separately) and use durable #8-32 screw terminals with captive star lock washers for secure electrical connections. The tin-plated copper buses and fuse clips provide excellent conductivity and corrosion resistance, making them ideal for demanding marine environments.

The Blue Sea 5035 is supplied with a clear insulating cover featuring a convenient push-button latch for easy fuse access. The cover meets ABYC/USCG insulation requirements, includes recessed areas for circuit labels, and is supplied with 20 write-on circuit labels for easy identification.

The Blue Sea 5037 is the open (no cover) version of this fuse block. Please note that the 5037 is a non-stocked item and is supplied to order, therefore a lead time will apply.
