This fuse is specifically engineered to protect high-output alternator circuits, large motor loads, and massive battery banks. Its space-efficient design allows it to be mounted directly to a battery terminal or heavy-duty busbar, effectively reducing the footprint required for high-current protection. Rated for ignition protection under SAE J1171, the MRBF-400 is ideal for use in enclosed engine compartments where safety and reliability are non-negotiable.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eEaton\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eBussmann series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eMRBF-400\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Type:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eMarine Rated Battery Fuse (MRBF)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Current:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e400 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Voltage:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e32V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e5,000A @ 32V DC \/ 10,000A @ 14V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition Protection:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSAE J1171\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIngress Protection:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIP66\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePhysical Characteristics:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Interface:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCompatible with M8 (5\/16\") studs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eHigh-temperature, transparent thermoplastic for visual terminal inspection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eTin-plated copper alloy terminals for maximum conductivity and oxidation resistance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCompact single-pole, direct-mount architecture\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eApplication:\u003c\/strong\u003e The MRBF-400 is the premier choice for primary circuit protection in large-scale marine vessels, expedition RVs, and industrial mobile power units.
