Rated to 48 volts DC with a switchable manual reset, it doubles as an on\/off switch and carries the standards a surveyor actually looks for.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Sea-Dog SD-17 is a resettable thermal circuit breaker built to protect a heavy DC circuit on your boat. It's rated for 150 amps at up to 48 volts DC, so it covers the big loads: bow thrusters, windlasses, inverters, and main battery feeds where you want real overcurrent protection close to the source.\u003c\/p\u003e\n\u003cp\u003eThis one's a panel-mount breaker with a manual, switchable reset. That means it doubles as an on\/off switch. Flip it to cut power to the circuit for service, flip it back to restore it. And if it trips on an overload, you reset it by hand once the fault clears. No fuses to carry, no spares to hunt for in a hatch at the worst possible time.\u003c\/p\u003e\n\u003cp\u003eThe terminals are 1\/4 inch-28 studs, so you're landing proper ring terminals and torquing them down, not fighting a push-on spade connector on a 150-amp feed. The housing is black plastic with an IP67 protection rating, which means it shrugs off spray and brief immersion. Good for an exposed helm, a console, or a semi-protected battery compartment.\u003c\/p\u003e\n\u003cp\u003eWhere it earns its keep is the standards list. It's built to SAE J1625, ABYC E-11, UL 1077, and SAE J1171 requirements. If you've ever had a survey flag a non-compliant breaker, you know that matters. ABYC E-11 is the one your insurance and your surveyor care about for DC systems, and the J1171 ignition-protection standard means it's rated for use near a gas engine compartment.\u003c\/p\u003e\n\u003cp\u003eOne sizing note: pick the breaker to protect the wire, not the load. A 150-amp breaker wants wire rated to carry that current safely. If you're not sure what gauge you're running, give us a shout before you wire it in. Getting the breaker, the wire, and the load matched is the whole point.\u003c\/p\u003e\n\u003cp\u003eSold as a single breaker. It's a straightforward panel-mount install with two stud terminals.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eRated 150 amps at up to 48 volts DC for heavy marine loads like thrusters, windlasses, and inverters\u003c\/li\u003e\n  \u003cli\u003eManual switchable reset doubles as an on\/off switch for the circuit\u003c\/li\u003e\n  \u003cli\u003eResettable thermal design, so there's no fuse to replace after a trip\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch-28 stud terminals for secure ring-terminal connections on high-amperage feeds\u003c\/li\u003e\n  \u003cli\u003eIP67 protection rating stands up to spray and brief immersion\u003c\/li\u003e\n  \u003cli\u003eBuilt to SAE J1625, ABYC E-11, UL 1077, and SAE J1171 standards\u003c\/li\u003e\n  \u003cli\u003eIgnition protected under SAE J1171 for use near a gas engine compartment\u003c\/li\u003e\n  \u003cli\u003eBlack plastic housing in a panel-mount format\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\u003eHow many amps is the SD-17 rated for?\u003c\/summary\u003e\n    \u003cp\u003eIt's a 150-amp breaker rated for circuits up to 48 volts DC.
