MRBF Terminal Fuse - 250 Amp

Egis Mobile Electric MRBF Terminal Fuse - 250 Amp

The Egis Mobile Electric MRBF Terminal Fuse - 250 Amp (3603-250) delivers reliable DC overcurrent protection for marine and vehicle electrical installations. Rated for 250A continuous current at up to 58 VDC, this fuse easily supports 12V, 24V, and 48V nominal systems. Its high interrupt rating of 10,000A at 14 VDC and 5,000A at 48 VDC fully satisfies ABYC requirements for DC main circuit protection on large or paralleled battery banks, making it an ideal choice for high-capacity lithium and lead-acid installations alike.

The transparent fuse body provides an instant visual indication of fuse status without the need for tools or testing equipment, saving time during diagnostics and maintenance. Color-coding further simplifies identification of the correct amperage rating at a glance. The fuse is ignition-protected in accordance with SAE/J1171-ISO8846, making it safe for installation in enclosed compartments where potentially explosive gases may be present.

Built for harsh marine and mobile environments, the MRBF fuse features a rugged design that resists shock and vibration, and an IP66 ingress protection rating that seals the unit against dust and water intrusion. This ensures long-term reliability and consistent circuit protection throughout the life of the electrical system. The product is backed by a 4-year manufacturer warranty.
