Blue Sea Systems ST Blade Fuse Block with Negative Bus and Cover

The Blue Sea Systems ST Blade Fuse Block with Negative Bus and Cover is a compact marine-grade fuse panel. It protects and organizes DC branch circuits on boats, RVs, trucks, and custom automotive and powersports electrical systems. It replaces the tangle of in-line fuses with one tidy, easy-to-service block, and it takes common ATO/ATC blade fuses.

Key Features:

• Accepts standard ATO and ATC fast-acting blade fuses, which are sold separately
• Built-in negative bus lets you terminate ground connections in one place, which cuts wiring clutter and makes troubleshooting easier
• Tin-plated copper buses and fuse clips resist corrosion and conduct well in harsh environments
• Positive distribution bus with a #10-32 stud for the feed connection
• Rated for 32V DC, so it suits both 12V and 24V nominal systems
• Can be used for 24-hour (always-on) circuits
• Accepts ring or snap fork type terminals
• Clear insulating cover meets ABYC/USCG insulation requirements
• Push-button latch opens the cover easily for fuse access
• Cover has storage for spare fuses and label recesses that accept Blue Sea Systems Small Format Labels for circuit identification

A fuse block guards wiring against damage and fire risk from overloads and short circuits. This one is a good choice for new installations, or for adding circuits when a breaker panel has run out of positions. It can be fed from a single breaker or source and supplies power to several protected circuits. Blue Sea Systems is a trusted name in marine and mobile electrical hardware, and this line has the same durable build and clean layout that installers expect from the brand.
