Blue Sea 5032 ST-Blade Split Bus Fuse Block

Description

The Blue Sea 5032 ST-Blade Split Bus Fuse Block provides twelve ATO/ATC fuse circuits divided into two electrically isolated groups of six. This makes it useful for boats with two separate battery sources or for systems that need to separate always-live 24-hour circuits from circuits controlled by the main battery switch.

Screw terminals accept ring terminals for secure wiring connections, while tin-plated copper buses and fuse clips provide conductivity and corrosion resistance. Each half of the block can be supplied independently, allowing two battery banks or two different distribution strategies to share one compact fuse panel.

The clear insulating cover includes label recesses and storage for two spare fuses while satisfying applicable ABYC and USCG insulation requirements. A push-button latch makes the cover easy to open for fuse replacement, and the integrated negative-bus connection helps organize return wiring. Fuses are sold separately. For marine DC systems that need two isolated groups of blade-fuse circuits in one block, the 5032 provides a flexible distribution solution.
