Egis Mobile Electric MRBF Terminal Fuse 50 Amp
The Egis Mobile Electric MRBF Terminal Fuse 50 Amp is a precision-engineered circuit protection device designed to safeguard marine, RV, and vehicle electrical systems from short circuit events and over-current loads. Built for demanding mobile environments, this fuse mounts directly at the battery terminal and provides reliable protection for high-current DC applications across a wide voltage range of 12V to 48V nominal (rated to 58 VDC).
The transparent housing allows quick visual verification of fuse condition without the need for tools or a meter, streamlining maintenance and troubleshooting. The ignition-protected design complies with SAE/J1171 and ISO8846 standards, ensuring safe installation in closed compartments where flammable or explosive gases may be present — a critical requirement in marine environments.
With an exceptional interrupt rating of 10,000 amps at 14 VDC, 5,000 amps at 48 VDC, and 2,000 amps at 58 VDC, this fuse safely handles the available fault current from large paralleled battery banks, exceeding ABYC requirements for DC main circuit protection. The IP66 ingress protection rating ensures complete sealing against dust and powerful water jets, maintaining reliable circuit protection throughout the life of the installation.
Color-coded for instant identification of amperage rating and constructed to resist shock and vibration, this fuse is equally at home on high-performance marine vessels, emergency vehicles, work trucks, and recreational vehicles. It is backed by Egis Mobile Electric's industry-leading 4-year manufacturer warranty.
