The switch is rated for 175 amps continuous and 800 amps intermittent, making it suitable for cutting power to marine electrical circuits that see high startup or surge loads. Current flows through 3\/8 inch brass terminals, chosen for their conductivity and corrosion resistance in a marine environment. The lever itself is chrome plated brass, giving it a durable, corrosion resistant finish that stands up to salt air and routine handling. A faceplate is included, allowing for a finished, panel-mounted installation. Operation is simple: the lever moves between on and off positions, giving boat owners a fast, manual way to fully disconnect the battery without pulling cable terminals. This switch is a straightforward replacement or upgrade for existing lever operated disconnect switches on boats, and its compact footprint suits helm panels, battery compartments, and other mounting locations where a manual disconnect is needed. Weighing 1.07 pounds, it is a rugged, panel-mount component intended for direct-current marine electrical systems.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e MP38910\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Lever Operated Battery Disconnect Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current Rating:\u003c\/strong\u003e 175 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntermittent Current Rating:\u003c\/strong\u003e 800 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Size:\u003c\/strong\u003e 3\/8 inch brass terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLever Material\/Finish:\u003c\/strong\u003e Chrome plated brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Hardware:\u003c\/strong\u003e Faceplate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\/Finish:\u003c\/strong\u003e Chrome\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.07 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the current rating of the Sierra MP38910 battery disconnect switch?\u003c\/strong\u003e The MP38910 is rated for 175 amps continuous and 800 amps intermittent, so it can handle both steady loads and short high-current surges on a marine 12-volt circuit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the MP38910 a manual or automatic disconnect switch?\u003c\/strong\u003e It is a manual, lever operated switch.
