Swift Kompany 3903 Sealed ANL Fuse Block 35-750A, up to 4/0 AWG Cable

The Swift Kompany 3903 is a sealed ANL fuse block for protecting high-current DC circuits, such as battery cables, inverters, windlasses and thrusters. It accepts ANL fuses from 35 to 750 amps and handles cables up to 4/0 AWG. It works as a heavy-duty fuse holder in marine, RV and automotive power systems.

Key Features:

• Fuse type: ANL, rated 35-750A
• Maximum voltage: 80 Vdc
• Separate stud connections: let heavier-gauge cables and terminals feed in and out without landing on the fuse tab
• Tin-plated copper busbar: delivers strong electrical performance with minimal voltage drop
• Ignition protected: suitable for installation in potentially hazardous gaseous environments such as LPG or gas boats
• Sealed construction: IP66, IP67 and IP6K9K ingress protection ratings
• Glass-filled nylon body: durable in demanding environments
• Stainless steel self-locking hardware: keeps connections secure over the long term
• Transparent protective cover: has break-away tabs for cable and terminal access and lets you inspect the fuse
