MRBF Terminal Cube Fuses (50A - 300A)

Protect high-current DC circuits directly at the battery terminal. Standard inline fuses leave the initial cable length unprotected against short circuits and fire hazards. The fuse itself consists of a metal strip mounted in an insulated ceramic block, which is fitted to a holder or clamp with an isolation nut, ensuring that all current passes through the fuse and not through the stud itself.

Their ultra-compact footprint simplifies mounting in tight battery boxes, offering a far more space-efficient and cost-effective solution. Each fuse features a clear inspection window to easily verify if the fuse has blown.

Key Features

• Terminal-Direct Protection: Mounts directly at the battery post via Single Stud or Twin Stud holders.
• Isolated Current Flow: Engineered with an insulating bushing and isolation nut so full current routes strictly through the fuse element.
• Compact & Easy Mounting: Minimal footprint fits effortlessly into restricted engine bays and small battery enclosures.
• Cost-Effective Alternative: Provides high-capacity protection at a fraction of the cost.
• Visual Indicator: Clear inspection window to easily verify if the fuse has blown.
• High Interrupt Rating (AIC): Built to safely clear high short-circuit currents on large battery banks.
