It protects your wiring and gear from overloads and shorts, and when it trips you just flip it back on. Panel-mount body, IP67-sealed, and built to marine standards. No fuses to hunt for in a drawer.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Sea-Dog SD-17 is a resettable thermal circuit breaker rated for 70 amps on a 48-volt DC system. It's the kind of part you don't think about until you need it, and then you're really glad it's there. When a circuit pulls more current than it should, this breaker trips and cuts the power before your wiring cooks or your gear gets damaged. No blown fuse to dig out of a drawer at the worst possible moment. You just reset it and get back to what you were doing.\u003c\/p\u003e\n\u003cp\u003eThe 48-volt rating is the tell here. This isn't a breaker for your nav lights or your stereo. It's built for the heavy stuff. Think 48-volt trolling motors, windlasses, bow thrusters, and larger house-bank runs where a standard 12-volt breaker simply won't hold up to the voltage. If you've rigged up a serious electric drive or a high-draw accessory, this is the protection that circuit deserves.\u003c\/p\u003e\n\u003cp\u003eWhat makes the SD-17 handy is the manual switchable reset. It works as a breaker and a switch at the same time. You can flip it by hand to kill the circuit for service or storage, then flip it right back on. That means one part does two jobs on your panel, and you don't need a separate disconnect switch upstream.\u003c\/p\u003e\n\u003cp\u003eSealing is where a lot of cheap breakers fall down, and this one doesn't. The SD-17 carries an IP67 protection rating, so it shrugs off dust and short-term water immersion. Mount it in a splashy center console, a semi-exposed helm, or down near the bilge, and it'll keep doing its job. The 1\/4 inch-28 stud terminals give you a proper high-current landing for ring terminals, and they lock down tight so vibration won't loosen the connection over a season of pounding.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward. It's a panel-mount design, so it drops into a dash or breaker-panel opening for a clean, finished look. And it's built to the standards that matter on the water. The SD-17 meets SAE J1625, ABYC-E11, UL1077, and SAE J1171, which is exactly the paperwork a surveyor or an insurer likes to see behind your electrical work. Black plastic housing, single breaker, ready to wire in.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e70 amp rating protects heavy DC loads like 48-volt trolling motors, windlasses, and thrusters without nuisance tripping.\u003c\/li\u003e\n  \u003cli\u003e48 volt DC design matches high-voltage trolling motor and house-bank systems where a 12-volt breaker won't hold up.\u003c\/li\u003e\n  \u003cli\u003eManual switchable reset works as a breaker and an on\/off switch in one, so you can kill the circuit right at the panel.\u003c\/li\u003e\n  \u003cli\u003eIP67 protection rating seals out dust and short-term water immersion for splash-prone consoles and bilge-area installs.\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch-28 stud terminals give you a solid, high-current connection that won't back out with vibration.\u003c\/li\u003e\n  \u003cli\u003ePanel-mount body drops into an existing dash or breaker-panel opening for a clean, finished install.\u003c\/li\u003e\n  \u003cli\u003eMeets SAE J1625, ABYC-E11, UL1077, and SAE J1171 standards that surveyors and insurers look for.\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\u003eWhat amperage is the Sea-Dog SD-17 rated for?\u003c\/summary\u003e\n    \u003cp\u003eIt's a 70 amp breaker rated for a 48-volt DC circuit.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eCan I use this breaker as an on\/off switch too?\u003c\/summary\u003e\n    \u003cp\u003eYes.
