It features a manual reset button, so a tripped circuit can be restored on the spot without replacing a fuse. The breaker is ignition protected, meaning it is safe to install aboard gasoline powered boats, and it works on both 12VDC and 24VDC electrical systems.\u003c\/p\u003e\u003cp\u003eConstruction is injection molded nylon and polycarbonate housing with stamped brass #10-32 studs and nuts, giving the breaker a corrosion resistant, marine-grade build.

This particular unit does not include the splash proof breaker cover, which is sold separately for installations needing extra weather protection. The breaker complies with SAE standard J553 and SAE J1171, the recognized standards for marine circuit protection devices.\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 420843-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 30 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12 or 24 Volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCover Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension A:\u003c\/strong\u003e 1-5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension B:\u003c\/strong\u003e 1-7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension C:\u003c\/strong\u003e 1-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimension D:\u003c\/strong\u003e 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Injection molded nylon and polycarbonate, stamped brass studs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Bolt-on mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Poles:\u003c\/strong\u003e 3\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\u003eIgnition Protected:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat amperage is the Sea-Dog 420843-1 circuit breaker rated for?\u003c\/strong\u003e The Sea-Dog 420843-1 is rated for 30 amps, making it suited to higher amperage marine accessories that need dedicated overcurrent protection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this breaker work on both 12 volt and 24 volt systems?\u003c\/strong\u003e Yes, the 420843-1 can be used on either 12VDC or 24VDC marine electrical systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 420843-1 come with a splash proof cover?\u003c\/strong\u003e No, this version of the breaker does not include the splash proof breaker cover.
