Frequently Asked Questions

AI
MRBF stands for Marine Rated Battery Fuse. These are high-amperage fuses designed for DC circuits up to 58V, commonly used in marine, automotive, and RV applications to protect against short circuits.
Select a fuse with an amperage rating slightly higher than the maximum current draw of your protected circuit. For example, use a 100A fuse for circuits drawing up to 100A, ensuring it does not exceed the wire's capacity.
Most MRBF terminal fuses in this list feature IP66 waterproof ratings and include protective caps. This ensures reliable operation in wet environments like marine decks or under-hood automotive applications.
