The Blue Sea 5032 ST-Blade Split Bus Fuse Block provides two isolated groups of six ATO/ATC circuits in a single block. It is designed for boaters running two isolated batteries, or a single battery split between 24-hour and switched circuits, who need organized fuse protection for both groups.
A clear insulating cover with label recesses satisfies ABYC/USCG requirements and includes storage for two spare fuses, and an easy-open push-button latch gives quick access when a fuse needs checking or replacing. Screw terminals accept ring terminals directly, and tin-plated copper buses and fuse clips resist corrosion — note that fuses are sold separately. Browse more options in our panels, switches, and circuit breakers category.
Key Features: 12 circuits in 2 isolated groups of 6, rated 100A per block / 30A per circuit at up to 32V DC, push-button latch cover, ABYC/USCG-compliant, spare fuse storage, fuses sold separately, sold individually.
