It protects a high-current circuit and doubles as a manual switch, so you can kill the load by hand and reset it after a trip without ever touching a fuse.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you're running a big DC load on your boat, a bow thruster, a windlass, an inverter feed, or a larger trolling and house bank, the Sea-Dog SD-17 gives you the protection that circuit needs in one clean surface-mount package. It's an 80 amp resettable thermal breaker rated to 48 volts DC, which means it covers 12, 24, 36, and 48 volt systems without a second thought.\u003c\/p\u003e\n\u003cp\u003eHere's what we like about it. It's switchable. That means the SD-17 isn't just a breaker sitting quietly in line waiting for a fault. You can flip it by hand to isolate the circuit for service, then flip it back when you're done. And if the circuit ever pulls more than it should, the thermal element trips and cuts the load. You reset it manually once things cool off. No fuses to keep in a drawer, no crimping in a new link at the dock.\u003c\/p\u003e\n\u003cp\u003eThe housing is black plastic and it's built to mount on the surface of a panel or bulkhead, so you don't need to cut a big hole to recess it. Power comes and goes through 1\/4 inch-28 stud terminals, which give you a solid, high-current connection you can torque down properly. That matters at 80 amps. Loose terminals make heat, and heat is what you're trying to avoid in the first place.\u003c\/p\u003e\n\u003cp\u003eIt carries an IP67 protection rating, so it shrugs off dust, spray, and a temporary dunk. That's the rating you want for anything living in a bilge, a console, or an open lazarette where water finds its way in eventually. Sea-Dog builds the SD-17 to SAE J1625, ABYC-E11, UL1077, and SAE J1171 standards, so it lines up with the marine wiring practices a surveyor or an insurer expects to see.\u003c\/p\u003e\n\u003cp\u003eOne honest note on sizing. An 80 amp breaker protects the wire and the device on that circuit, so match it to the gauge and the load you're actually running. If you're not sure what amperage your circuit calls for, give us a shout before you order. We'd rather get you the right breaker than send you a return.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e80 amp rating at 48 volts DC, works across 12V, 24V, 36V, and 48V systems\u003c\/li\u003e\n  \u003cli\u003eSwitchable design doubles as a manual on\/off switch, isolate the circuit by hand for service\u003c\/li\u003e\n  \u003cli\u003eResettable thermal trip, no fuses to stock or replace after an overload\u003c\/li\u003e\n  \u003cli\u003eIP67 protection rating, sealed against dust, spray, and temporary submersion\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch-28 stud terminals for solid, torque-down high-current connections\u003c\/li\u003e\n  \u003cli\u003eSurface-mount black plastic housing, no recessed cutout required\u003c\/li\u003e\n  \u003cli\u003eBuilt to SAE J1625, ABYC-E11, UL1077, and SAE J1171 marine standards\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 Sea-Dog 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\u003eCan the SD-17 be used as an on\/off switch?\u003c\/summary\u003e\n    \u003cp\u003eYes.
