Fuse blocks organize and protect six marine DC branch circuits in a compact, serviceable layout. The Blue Sea Systems 5033 accepts ATO and ATC fast-acting blade fuses, helping simplify fuse access and branch-circuit wiring on boats and other 12/24V DC systems.

The ST Blade Fuse Block uses tin-plated copper buses and fuse clips rated for up to 30 amperes per circuit. Its positive distribution bus provides a common feed for the six circuits, while the open, coverless format keeps installed fuses visible and accessible. The block accepts ring or snap-fork terminals and is designed for screw-terminal marine electrical installations. Fuses are sold separately.

  • Six-circuit configuration organizes multiple DC branch circuits in one location.
  • Accepts ATO and ATC fast-acting blade fuses for common marine fuse requirements.
  • Tin-plated copper buses and fuse clips support conductivity and help resist corrosion in marine environments.
  • Up to 30 amperes per circuit provides protection for appropriately sized branch circuits.
  • Positive distribution bus with a #10-32 stud simplifies the main power connection.
  • Coverless construction keeps fuses accessible for inspection and replacement.
Use the 5033 to consolidate separate in-line fuses into a centralized fuse block for accessory, helm, lighting, navigation, and other marine DC branch circuits. The six positions provide an organized connection point where each circuit can receive its own appropriately sized ATO or ATC fuse.
The tin-plated copper bus and fuse clips support reliable electrical contact while offering corrosion resistance suited to wet marine settings. Screw terminals accept ring or snap-fork terminals, making the block practical for serviceable boat wiring installations. Because this model does not include a cover or negative bus, install it where exposed fuse access is appropriate and provide separate negative distribution as required by the system design.
