Sierra Marine Battery Fuse Holder MRBF

The Sierra Marine Battery Fuse Holder MRBF line provides compact, high-current circuit protection for boats. It is designed around the Marine Rated Battery Fuse (MRBF) format and protects DC main, bow thruster, inverter and windlass circuits right at the battery power source.

Key Features:

• Mounts on the positive battery stud to protect the circuit directly at the power source
• Ignition protected when used with Sierra MRBF fuses, for use in gasoline-powered boats and enclosed engine spaces
• Bolt-down design that holds up in high-vibration marine environments
• Isolated M8 stud design that accepts standard hardware and lets terminals be stacked
• Protective insulating cap helps prevent accidental shorts
• Compact size suits tight spaces where high-amperage protection is needed
• Meets ABYC requirements for DC main circuit protection on large battery banks, thanks to a high interrupt rating
• Clear fuse display makes a blown fuse easy to spot, and a color-coded amperage identifier makes ratings easy to tell apart

The MRBF system covers a range of amperage ratings, so you can match the protection to the load on your boat's electrical system. Sierra is a long-established name in marine parts. This line suits boat owners and installers who want a compact, dependable battery-side fuse solution, also called an MRBF fuse block or marine battery terminal fuse holder.
