Bay Marine Supply Fuse Holders Editorial Review

Bay Marine Supply offers a reliable and well-built 150A Marine Rated Battery Fuse MRBF Terminal Fuse Only for direct connection to batteries, terminal bars, or high amperage switches on DC battery-powered systems. The fuse is a primary function to protect the wire from melting by blowing in a fraction of a second on a dead short to a battery. It goes for about nine hours at the rated amperage and 60 seconds at 200% of the rated amperage. The product is a bit costly compared to other sources, but it is worth every penny. The fuse fits Bluesea MRBF mounts and works effectively in protecting a bank of batteries on RV and upgrading the power from 1000W to 2000W.
