Blue Sea ST Blade Fuse Block – 12 Circuits with Negative Bus and Cover

A 12-circuit ST blade fuse block with a positive distribution bus on a #10-32 stud, plus a negative bus — suitable for 24-hour circuits. The clear insulating cover meets ABYC/USCG requirements, opens on a push-button latch, and holds two spare fuses plus Blue Sea’s Small Format Labels for circuit ID.

Tin-plated copper buses and fuse clips accept ring or spade terminals, and take ATO/ATC fast-acting blade fuses (fuses and labels sold separately).
