{"product_id":"sea-dog-420830-1-thermal-ac-dc-circuit-breaker-30-amp-push-to-reset-panel-mount-marine-breaker","title":"Sea-Dog Thermal Circuit Breaker - 30 Amp, Single Pole Panel Mount","description":"\u003cp\u003eThis Sea-Dog thermal circuit breaker delivers reliable 30 amp overcurrent protection for onboard 12-volt DC electrical circuits. Built as a single-pole, panel-mount unit, it installs directly into a boat's switch or breaker panel to protect wiring and connected equipment from overload and short-circuit conditions. When the rated current is exceeded, the internal thermal element trips the breaker, opening the circuit before wiring or components can be damaged; once the fault is cleared, the breaker can be reset and returned to service, unlike a one-time fuse.\u003c\/p\u003e\u003cp\u003eThe panel-mount design keeps the breaker accessible at the helm or breaker panel for quick manual reset, making it a straightforward upgrade or replacement for boat owners standardizing their electrical panel on a single breaker type and amperage. As a single-pole breaker rated for 30 amps, it is sized for higher-draw 12-volt circuits such as pumps, accessories, or other equipment drawing up to that threshold. It is sold as a standalone breaker for installation into an existing panel cutout rather than as part of a switch panel assembly.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sea-Dog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 420830-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 30 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit Breaker Type:\u003c\/strong\u003e Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Panel Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Poles:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 035514420327\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGTIN:\u003c\/strong\u003e 00035514420327\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.084 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Marine Circuit Breaker\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat amperage is the Sea-Dog 420830-1 circuit breaker rated for?\u003c\/strong\u003e It is rated for 30 amps, sized for higher-draw 12-volt DC marine circuits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a single-pole or double-pole breaker?\u003c\/strong\u003e The Sea-Dog 420830-1 is a single-pole (1-pole) circuit breaker.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the Sea-Dog 420830-1 mount in a boat's electrical panel?\u003c\/strong\u003e It is a panel-mount breaker, designed to install into a standard breaker or switch panel cutout.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this breaker be reset after it trips?\u003c\/strong\u003e Yes, as a thermal circuit breaker the Sea-Dog 420830-1 can be reset once the overload or fault condition is cleared, rather than being replaced like a fuse.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does the circuit breaker type mean for this Sea-Dog unit?\u003c\/strong\u003e It is listed as a Standard circuit breaker type, meaning it uses a conventional thermal trip mechanism for overcurrent protection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sea-Dog 420830-1 weigh?\u003c\/strong\u003e The Sea-Dog 420830-1 circuit breaker weighs 0.084 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sea-Dog 420830-1 breaker?\u003c\/strong\u003e Its UPC is 035514420327 (GTIN 00035514420327).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sea-Dog 420830-1 include mounting hardware or a panel?\u003c\/strong\u003e This is sold as the breaker itself for installation into an existing panel; a separate switch panel is not included.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of circuit is the Sea-Dog 420830-1 designed for?\u003c\/strong\u003e It is designed for 12-volt DC marine electrical circuits protecting pumps, accessories, and other onboard equipment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sea-Dog 420830-1 a genuine Sea-Dog part?\u003c\/strong\u003e Yes, part number 420830-1 is a genuine Sea-Dog thermal circuit breaker.\u003c\/p\u003e","brand":"Sea-Dog","offers":[{"title":"Default Title","offer_id":48988778987739,"sku":"S-D-420830-1","price":5.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/5672_72eba0b5-6195-4476-be84-066057990b80.jpg?v=1784429419","url":"https:\/\/www.goodvibesmarina.com\/products\/sea-dog-420830-1-thermal-ac-dc-circuit-breaker-30-amp-push-to-reset-panel-mount-marine-breaker","provider":"Good Vibes Marina","version":"1.0","type":"link"}
