Blue Sea Systems 7720 MAXI Fuse Block, 32 Volt DC Ignition-Protected Marine Fuse Block with Sealed Cover

The Blue Sea Systems 7720 is a MAXI Fuse Block built for circuit protection aboard gasoline or diesel powered boats. It is ignition protected, making it suitable for installation in engine compartments and other areas where spark-producing electrical equipment must meet marine ignition protection standards. A sealed cover shields the fuses from moisture, salt spray, and other harsh marine environmental exposure, helping prevent corrosion at the fuse terminals and extending the reliable service life of the block.

The cover also functions as an insulating cover, satisfying ABYC/USCG insulation requirements for exposed electrical connections on board. The block is constructed of plastic and is DIN rail mountable, allowing it to be installed alongside other DIN rail electrical components in a boat's electrical panel or distribution area for a clean, organized installation. It is rated for 32 Volts DC, matching standard marine low-voltage DC electrical systems. The 7720 measures 8 x 4 x 2 inches and weighs 0.15 pounds, making it a compact addition to a 12V or 24V marine DC distribution system.
