Seachoice 11276 Splash-Proof ATC Fuse Block – 4 Circuit
Free returns on all eligible orders
You have 30 days to request a return. All sale items are final sale.
The Seachoice 11276 is a 4-circuit splash-proof ATC fuse block for adding independently fused circuits to a marine electrical system. Each of the four circuits is fully isolated — power is not shared through a common bus, so a blown fuse on one circuit does not affect the others. Each pole has its own 1/4" male quick-connect terminal for clean, secure wiring connections.
A back plate behind the block provides additional electrical isolation and safety. The clear polycarbonate cover seals with an O-ring to keep out moisture and contaminants, and allows visual inspection of fuse condition without removing the cover. Rated at 15A per circuit. Fuses are not included.

- Back plate for electrical isolation and safety

Best Use Case: Ideal for adding fused accessory circuits to a helm panel, console, or electrical distribution area — common applications include powering VHF radios, chartplotters, bilge pump switches, navigation lights, and other 12V accessories. The isolated circuit design makes it a cleaner and safer alternative to running multiple accessories off a single unfused connection.
Parts Desk Insights: Each circuit is independently isolated — this is an important distinction from common-bus fuse blocks where all circuits share a single power input. The 15A per circuit rating is suitable for most standard marine accessories; confirm your accessory’s current draw before selecting fuse ratings. Fuses are sold separately — use standard ATC blade fuses. If you need more circuits, see the Seachoice 11277 Splash-Proof ATC Fuse Block – 8 Circuit.
