It protects a single branch, trips on overcurrent, and resets by hand. Sealed to IP67 and built to marine standards, it's a set-and-forget part for your dash or breaker panel.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Sea-Dog SD-17 is a 25 amp resettable thermal circuit breaker built for 48 volt DC circuits, and it's the kind of part you install once and stop thinking about. It protects a single branch circuit from overcurrent, trips when something draws more than it should, and resets by hand. No fuses to hunt for in a drawer at the worst possible moment.\u003c\/p\u003e\n\u003cp\u003eRated to 48 volts DC, it's a good match for higher-voltage house and accessory systems, including 36V and 48V trolling motor wiring where a 25 amp branch makes sense. It works just as well on 12V and 24V circuits, since a breaker rated for a higher voltage handles the lower ones fine. Think bilge pumps, electronics feeds, lighting circuits, or any accessory run you want to protect and be able to reset from the helm.\u003c\/p\u003e\n\u003cp\u003eThe reset is manual and switchable, so this breaker doubles as an on\/off switch for the circuit. Flip it to cut power for service, flip it back to restore. If the circuit faults, the breaker trips on its own and you reset it once the problem's sorted. That's one less switch to wire and one more way to kill a circuit fast.\u003c\/p\u003e\n\u003cp\u003eSealed to IP67, the SD-17 shrugs off spray, rain, and the occasional dunk. That matters on an open console or anywhere near the bilge. The housing is black plastic, and it panel-mounts through a single hole for a clean look at the dash or breaker panel. Connections are made to 1\/4 inch-28 stud terminals, so you're landing ring terminals under a nut, which is the connection you want on a boat that vibrates and pounds.\u003c\/p\u003e\n\u003cp\u003eIt meets SAE J1625, ABYC E-11, UL 1077, and SAE J1171 standards, so it's built to the specs surveyors and insurers expect on marine DC wiring. If you're rigging or refitting a panel and want overcurrent protection that resets instead of blows, this is a straightforward, honest choice.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e25 amp rating protects a single branch circuit from overcurrent\u003c\/li\u003e\n  \u003cli\u003e48 volt DC rated, works across 12V, 24V, and 48V systems\u003c\/li\u003e\n  \u003cli\u003eManual switchable reset doubles as an on\/off switch for the circuit\u003c\/li\u003e\n  \u003cli\u003eIP67 sealed housing stands up to spray, rain, and a splashdown\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch-28 stud terminals for secure ring-terminal connections\u003c\/li\u003e\n  \u003cli\u003ePanel mount design installs through a single hole at the dash or breaker panel\u003c\/li\u003e\n  \u003cli\u003eMeets SAE J1625, ABYC E-11, UL 1077, and SAE J1171 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\u003eWhat voltage and amperage is the Sea-Dog SD-17 rated for?\u003c\/summary\u003e\n    \u003cp\u003eIt's a 25 amp breaker rated for 48 volts DC.
