Description
- Four blade-fuse circuits under one cover
- 30A per circuit, 100A per block
- Ignition protected with the cover on
This is where the small stuff gets its own fuse: fish finder, bilge pump, nav lights, USB ports. One feed in, four fused circuits out, and the cover snaps over the fuses to keep spray and fingers off. It uses standard ATO/ATC fuses, sold separately. It has no negative bus, so pair it with a busbar like the Bluewater 4-gang. Our busbar and fuse block layout guide shows the layout, and the fuse size calculator sizes each fuse.
Good fit if: You have up to four small loads, each 30A or less, like a fish finder, bilge pump and nav lights.
Not the pick if: You need more than four circuits or more than 100A through the block. It has no negative bus, so pair it with a busbar like the Bluewater 4-gang.
