Samlex Replacement Terminal Fuse

The Samlex Replacement Terminal Fuse line offers Marine Rated Battery Fuses (MRBF), also called battery terminal fuses. They are made for high-current DC systems in RVs, boats, and solar and inverter installations. Each fuse protects cables and connected equipment, such as inverters, from short circuits. It does this by interrupting the current at the battery post.

Key Features:

• Compact terminal-mount design that fits onto the battery terminal stud, which suits tight spaces
• Gives short-circuit protection close to the battery, where fault current is highest
• Works as a replacement or spare fuse for Samlex DC-FA fuse assemblies and the DC-FB-2 double pole fuse bar
• Made for DC battery circuits in marine, RV and off-grid power systems

A fuse used in a battery circuit needs enough interrupting capacity (AIC) to handle short-circuit conditions safely. Keeping a Samlex replacement terminal fuse on hand helps you restore protection quickly after a fuse has blown.
