Built for heavy DC runs up to 4\/0 cable, it's the fuse holder you wire in once and don't think about again.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eRunning a big DC load, a bow thruster, an inverter, a windlass, a high-output alternator? You need that main fuse protected and easy to service. The Egis 3903 does exactly that. It takes one ANL fuse sized anywhere from 35 up to 750 amps, so a single part number covers a lot of different installs.\u003c\/p\u003e\n\u003cp\u003eThe busbar is tin-plated copper, which keeps voltage drop low and holds up in a salt-air bilge. Egis uses separate stud connections for the cable landings, so your heavy-gauge terminals feed in and out on their own studs instead of stacking on the fuse tab itself. That's a cleaner, more reliable connection on 4\/0 wire. The housing is glass-filled nylon with stainless self-locking hardware, and it's sealed to IP66, IP67, and IP6K9K.\u003c\/p\u003e\n\u003cp\u003eIt's ignition protected, so you can mount it on a gas boat or near an LPG locker without second-guessing it. Max voltage is 80 Vdc, which covers 12, 24, and 48-volt systems. Four #10 and two 1\/4-inch mounting holes lock it down solid. Backed by a 4-year warranty.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eFits a single ANL fuse rated 35 to 750 amps, so one block covers everything from accessory circuits to main battery runs\u003c\/li\u003e\n  \u003cli\u003eTin-plated copper busbar for low voltage drop and corrosion resistance in the bilge\u003c\/li\u003e\n  \u003cli\u003eSeparate stud connections keep heavy 4\/0 cable terminals off the fuse tab for a cleaner, more reliable landing\u003c\/li\u003e\n  \u003cli\u003eSealed to IP66, IP67, and IP6K9K and ignition protected for gas and LPG environments\u003c\/li\u003e\n  \u003cli\u003eGlass-filled nylon housing with stainless steel self-locking hardware, backed by a 4-year warranty\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 Electronics 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 size fuse does the Egis 3903 take?\u003c\/summary\u003e\n    \u003cp\u003eIt holds a single ANL fuse rated anywhere from 35 to 750 amps, so you size the fuse to your circuit.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eHow large a cable can I land on it?\u003c\/summary\u003e\n    \u003cp\u003eIt's built for cables up to 4\/0.
