It takes a single 225 to 400 amp Class-T fuse, handles up to 80 volts DC, and carries IP66, IP67, and IP6K9K sealing so spray and washdowns won't touch the connection.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Egis Mobile 3912 is a sealed Class-T fuse block built for the high-current DC circuits you'll find on a modern boat. Think lithium battery banks, big inverters, bow thrusters, anything pulling serious amperage off the bank. It takes a single Class-T fuse rated from 225 to 400 amps and handles up to 80 volts DC, so it covers 12, 24, and 48 volt systems without a problem.\u003c\/p\u003e\n\u003cp\u003eWhat makes this one worth the money is the sealing. The whole block carries IP66, IP67, and IP6K9K ratings, which means it shrugs off spray, washdowns, and the odd bilge soaking. The housing is glass-filled nylon and the busbar is tin-plated copper, so corrosion isn't going to creep in and cook your connection over a season. A clear polycarbonate cover snaps over the top to keep fingers and stray tools off a live terminal, and the stainless steel hardware self-locks so it won't back out with vibration.\u003c\/p\u003e\n\u003cp\u003eIf you're fusing a main battery feed and you want it done right, this is the kind of block you install once and forget about.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e80V DC rating with a 225 to 400 amp Class-T fuse window, sized for lithium banks, inverters, and main battery feeds\u003c\/li\u003e\n  \u003cli\u003eIP66, IP67, and IP6K9K sealing keeps spray, washdowns, and bilge moisture out of the connection\u003c\/li\u003e\n  \u003cli\u003eGlass-filled nylon housing and tin-plated copper busbar resist corrosion for long service life\u003c\/li\u003e\n  \u003cli\u003eClear polycarbonate cover protects the live terminal from fingers and stray tools\u003c\/li\u003e\n  \u003cli\u003eStainless steel self-locking hardware won't back out under engine and road vibration\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Egis Mobile reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat fuse does the Egis 3912 use?\u003c\/summary\u003e\n    \u003cp\u003eIt takes a single Class-T fuse rated between 225 and 400 amps.
