Description
The MRBF Terminal Fuse 300A (Part No. 5190) provides reliable circuit protection for high-current DC systems, ensuring safety and compliance with marine and vehicle electrical standards.
This fuse is designed for use with Terminal Fuse Blocks (PN 5191 or PN 2151) and must not be mounted directly to a battery terminal. With an ignition-protected design, it’s safe for installation aboard gasoline-powered boats, motorhomes, and off-grid battery systems.
Featuring a clear inspection window for quick visual indication of a blown fuse and colour-coded amperage markings for easy identification, the MRBF fuse delivers robust, compact protection for modern 12V–58V DC systems.
