The Blue Sea Systems ST Blade Compact Fuse Blocks provide reliable surface-mount circuit protection for ATO/ATC fuses in a space-saving design. Built for marine and vehicle electrical systems, these fuse blocks meet ABYC/USCG standards and offer ignition protection when the cover is secured—making them safe for installation in gasoline engine compartments.
Their single-side wire entry minimizes footprint while maintaining easy access for wiring and labeling. Each block includes write-on circuit labels and uses tin-plated copper buses and fuse clips for maximum corrosion resistance and long-term reliability.
Features:
Compact, ignition-protected design for 12/24V DC systems
Rated 30A per circuit and 100A per block (32V DC max)
Accepts ring or snap-fork terminals
Tin-plated copper bus bars and fuse clips
Includes write-on circuit labels
Fuses sold separately
