{"product_id":"sea-dog-sd-17-100a-48v-dc-circuit-breaker","title":"Sea-Dog SD-17 100A 48V DC Circuit Breaker","description":"\u003cp class=\"nvn-hero\"\u003eThe Sea-Dog SD-17 is a 100 amp resettable thermal circuit breaker built to protect high-current DC circuits on your boat. It handles systems up to 48 volts, panel mounts through the dash, and doubles as a manual switch thanks to its switchable reset lever. IP67 sealed and ABYC certified.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eWhen you're running a big load off your DC system, a windlass, a bow thruster, an inverter feed, or a trolling motor circuit, you want overcurrent protection you can actually trust. That's what the Sea-Dog SD-17 does. It's a 100 amp resettable thermal circuit breaker rated for systems up to 48 volts DC, so it covers 12V, 24V, and 48V setups from one part.\u003c\/p\u003e\n\u003cp\u003eThe thermal element trips on sustained overcurrent and heat, then you reset it by hand. No fuse to hunt for, no spare to carry. And because it's a switchable-reset design, the lever also works as a manual on\/off switch. That's handy when you want to kill power to a circuit for service without pulling terminals or yanking a battery lead.\u003c\/p\u003e\n\u003cp\u003eIt panel mounts, so it sits clean in a dash, an electrical panel, or a switch box with the reset lever facing out where you can get to it. Wiring lands on 1\/4 inch-28 stud terminals, so you're crimping ring lugs and torquing them down, not fighting with push-on spades that back out over time. The housing is black plastic and sealed to IP67, which means it shrugs off dust and temporary water immersion. Good for open helms, bilge-area panels, and anywhere spray finds its way in.\u003c\/p\u003e\n\u003cp\u003eCertifications matter on the water, and this one's covered. It meets ABYC-E11, the standard your surveyor and your insurance company care about for AC and DC systems on boats. It also carries UL1077, SAE J1625, and SAE J1171 marks, so it's built to recognized supplemental protector and marine ignition-protection standards.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anybody wiring up a serious DC load and doing it right the first time. If you've got a high-amp accessory that needs its own protected feed, the SD-17 gives you a compact, resettable, code-compliant breaker that installs once and stays put. It ships as a single breaker, so order one per circuit you need to protect.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e100 amp rating handles high-current DC loads like windlasses, thrusters, and inverter feeds\u003c\/li\u003e\n  \u003cli\u003eRated to 48 volts DC, so one breaker covers 12V, 24V, and 48V systems\u003c\/li\u003e\n  \u003cli\u003eSwitchable reset lever doubles as a manual on\/off switch for servicing the circuit\u003c\/li\u003e\n  \u003cli\u003eResettable thermal design means no fuses to replace and no spares to carry\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch-28 stud terminals take ring lugs for a secure, vibration-proof connection\u003c\/li\u003e\n  \u003cli\u003eIP67 sealed black plastic housing resists dust and temporary water immersion\u003c\/li\u003e\n  \u003cli\u003eMeets ABYC-E11, UL1077, SAE J1625, and SAE J1171 standards\u003c\/li\u003e\n  \u003cli\u003ePanel-mount design fits dash, electrical panel, or switch box installations\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 systems does the SD-17 work with?\u003c\/summary\u003e\n    \u003cp\u003eIt's rated up to 48 volts DC, so the same breaker works on 12V, 24V, and 48V systems.
