Technical Specifications Part Type Battery Terminal Fuse (Fusible de Terminal de Batería) Amperage 300 Amps Voltage Rating 58V DC (Standard max for MRBF) Mounting Style Stud Mount (Montaje de Perno) - Requiere portafusible MRBF Materials Body: Ceramic & PC (Cerámica y Policarbonato) Element: Zinc Protection Type Ignition Protected (Seguro contra ignición / SAE J1171) Features & Benefits Maximum Protection: Typically the highest amperage available in the MRBF form factor, offering protection for the most demanding DC circuits found in marine and RV applications. Thermal Safety: The ceramic housing is critical at 300A, ensuring the fuse body does not melt or deform under the intense heat generated during a high-current event. Space Saving: Replaces bulky Class-T or ANL fuse blocks for main battery protection, mounting directly on the battery terminal to save space and reduce cable connections. Common Applications Heavy Duty Marine Large Bow Thrusters, Heavy Windlasses, Main DC Bus Feeds on large yachts. Power Conversion Inverters rated 3000W and above, Lithium Battery Bank main output protection. ⚠️ CRITICAL NOTE: At 300 Amps, correct cable sizing (typically 2/0 AWG or 4/0 AWG) and tight connections are vital to prevent overheating.
