Marinco 5191-BSS MRBF Terminal Fuse Block 30-300A

The Marinco 5191-BSS is a compact MRBF (Marine Rated Battery Fuse) Terminal Fuse Block designed for high-amperage circuit protection in marine and powersports applications. This single-position fuse block mounts directly on 3/8" battery posts, battery switches, or bus bars, providing an economical solution for meeting ABYC circuit protection requirements.

Key Features:

• Supports MRBF fuses rated from 30A to 300A for high-current applications
• Isolated stud design uses standard M8 hardware and permits stacking of terminals
• Accepts 5/16" ring terminals for secure connections
• Insulating cap prevents accidental shorts and electrical hazards
• Ignition protected when used with Blue Sea Systems MRBF Terminal Fuses
• Weatherproof construction suitable for harsh marine environments
• Maximum operating voltage: 58V DC
• Maximum operating amperage: 300A
• Recommended torque: 75 in-lbs

Ideal for protecting DC main circuits, inverters, windlass systems, bow thrusters, and other high-amperage equipment. This terminal fuse block provides essential circuit protection in tight spaces where traditional fuse panels won't fit. The compact design allows for installation directly at the battery terminal, ensuring that no section of cable remains energized in the event of a short circuit. Fuses sold separately.
