MRBF Terminal Fuse Block - Single Output, 30-300 A

EGIS MOBILE ELECTRIC MRBF Terminal Fuse Block - Single Output, 30-300 A

The Egis Mobile Electric MRBF Terminal Fuse Block - Single Output simplifies medium- and high-amperage circuit protection by mounting directly to battery terminals, XD Relay I/O terminals, or high-ampere bus-bar terminals. Designed for demanding marine and vehicle electrical environments, this compact fuse block is appropriate for DC Main, inverter, windlass, and bow thruster circuit protection. When used with Egis Mobile Electric MRBF fuses, the block is ignition protected, making it safe for installation in closed compartments where potentially explosive gases may be present.

Built for harsh environments, the block features shock and vibration resistance, an IP66 ingress protection rating to seal against dust and water intrusion, and high-temperature materials rated to 200°C. The tin-plated copper alloy conductor, stainless steel self-locking hardware, silicone rubber protective cover, and PPS base insulator ensure long-term reliability and safe mounting in any orientation. A 58 Vdc rating easily supports 12 to 48V nominal DC applications, with interrupt ratings of 5,000A at 48 Vdc and 2,000A at 58 Vdc. The product carries a 4-year warranty and is CE compliant to ISO 8846. It is a direct replacement for Blue Sea Systems #5191.
