Rated at 20 amps and usable on both 12 volt and 24 volt systems, it features a manual reset button so a tripped circuit can be restored at the breaker itself instead of replacing a fuse. The body is constructed of injection molded nylon and polycarbonate with stamped brass internals, and it terminates in #10-32 studs with nuts for a secure wired connection. The copper post is the battery, or \"power in,\" connection, while the silver post is the auxiliary, or \"power out,\" protected side of the circuit, making correct wiring straightforward to identify at installation.\u003c\/p\u003e\u003cp\u003eThis breaker is ignition protected, meaning it is rated safe for installation aboard gasoline powered boats near the engine compartment. It complies with SAE standard J553 and SAE J1171, the marine industry standards covering circuit breaker construction and performance. This version does not include the splash proof breaker cover; the cover is available separately as Sea-Dog part number 420840 for installations needing extra environmental protection.\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 420842-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 20 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\u003eCircuit Breaker Type:\u003c\/strong\u003e Resettable, Manual Reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCover Included:\u003c\/strong\u003e No (cover sold separately as Sea-Dog 420840)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e #10-32 studs with nuts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stamped Brass \/ Injection Molded Nylon \/ Polycarbonate\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 0.06 pounds\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 Protection:\u003c\/strong\u003e Ignition Protected\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 035514420730\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat amperage is the Sea-Dog 420842-1 rated for?\u003c\/strong\u003e The Sea-Dog 420842-1 is rated at 20 amps and is designed for use with higher-amperage accessories on a boat's electrical system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this breaker work on both 12 volt and 24 volt systems?\u003c\/strong\u003e Yes, the Sea-Dog 420842-1 can be used on either 12 volt or 24 volt systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 420842-1 include a breaker cover?\u003c\/strong\u003e No, the 420842-1 is the version without a cover.
