Dual Stud MRBF Terminal Fuse Holder (300A)

Protect two independent high-current DC circuits directly from a single battery post using this compact twin-stud MRBF fuse holder. Designed to eliminate unprotected cable runs, it mounts straight onto an M10 battery stud or terminal clamp, allowing you to feed two separate loads—such as  inverter, windlass, bow thruster, etc—right at the energy source.

The dual-stud arrangement features isolated M8 stainless steel studs and an insulating base designed to handle up to 300A total combined. It includes a flexible insulating cap to guard against accidental shorts, making it an essential space-saver for campervans, marine, commercial vehicles, and motorhomes.

Key Features

• Dual-Circuit Terminal Protection: Consolidates protection for two independent circuits onto a single M10 battery terminal connection.
• Isolated Stud Engineering: Isolated stainless steel stud, ensuring full circuit current flows strictly through the fuse element rather than the mounting hardware.
• Protective Insulating Cap: Includes a flexible red vinyl cover to shield live connections and prevent accidental short circuits.
• Compact Footprint: Space-saving design eliminates heavy inline fuse holders in tight battery enclosures and engine bays.
• Ignition Protected: Safe for installation in petrol-powered engine compartments and enclosed battery spaces when paired with an MRBF fuse.
