Blue Sea Systems Waterproof ATO/ATC Fuse Holder – BSS-5065
Protect your ATO/ATC blade fuses from moisture, spray, and the corrosive marine environment with this purpose-built waterproof fuse holder from Blue Sea Systems. The BSS-5065 is designed for inline installation on DC circuits aboard your vessel, keeping standard ATO/ATC fuses secure and sealed against water intrusion — a common cause of fuse failure and nuisance electrical faults on boats.
The waterproof housing snaps securely closed over the fuse, making it easy to inspect and replace fuses in the field while maintaining a reliable seal in wet or exposed locations such as bilge areas, engine compartments, and cockpit wiring runs.

- Accepts standard ATO/ATC blade fuses

Parts Desk Insights
Best Use Case: The BSS-5065 is the right choice when you need to protect an ATO/ATC blade fuse in a wet or exposed location — particularly for bilge pump wiring, engine compartment accessory circuits, and any inline run where the fuse is subject to spray or condensation. If your application requires a panel-mount solution instead of inline, consider the Panel Mount Cap Fuse Holder (BSS-5022). For AGC/MDL-style fuses, the Inline AGC/MDL Fuse Holder (BSS-5063) is the appropriate alternative. For high-current applications requiring MAXI fuses up to 80A, see the MAXI Inline Fuse Holder (BSS-5068).
