It features a manual reset button, so a tripped circuit can be restored with a simple push rather than replacing a fuse. The breaker is ignition protected, making it safe to install aboard gasoline powered boats, and it operates on either 12 volt or 24 volt DC systems.\u003c\/p\u003e\u003cp\u003eConstruction is injection molded nylon and polycarbonate with stamped brass #10-32 studs and nuts for secure, corrosion-resistant wiring connections. The two posts are functionally distinct: the copper post is the battery, or power in, connection, and the silver post is the auxiliary, or power out, protected connection, so wiring is straightforward once the posts are identified correctly. The 420845-1 does not include a cover; a matching splash proof breaker cover is available separately as Sea-Dog part 420840 for installations that need extra protection from moisture. This breaker complies with SAE standard J553 and SAE J1171.\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 420845-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 50 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12 or 24 Volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset Type:\u003c\/strong\u003e Manual Reset Button (Resettable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCover Included:\u003c\/strong\u003e No (splash proof cover sold separately, Sea-Dog 420840)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Injection Molded Nylon and Polycarbonate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStud Type:\u003c\/strong\u003e Stamped Brass #10-32 Studs with Nuts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition Protected:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards Compliance:\u003c\/strong\u003e SAE J553, SAE J1171\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 4.9 inches D x 4 inches W x 1.3 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.062 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 035514423809\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThis is a universal marine circuit breaker for use with higher-amperage 12 volt or 24 volt DC accessory circuits; it is not restricted to a specific boat make, model, or engine.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003eNo OEM cross-reference numbers are specified for this part.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat amperage is the Sea-Dog 420845-1 circuit breaker rated for?\u003c\/strong\u003e The 420845-1 is rated for 50 amps, making it suitable for higher-amperage marine accessory circuits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this breaker be used on both 12 volt and 24 volt systems?\u003c\/strong\u003e Yes, the Sea-Dog 420845-1 is designed to work on either 12 volt or 24 volt DC systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 420845-1 come with a protective cover?\u003c\/strong\u003e No, the 420845-1 is sold without a cover.
