It is designed for use with 12, 24, and 32 volt marine electrical systems under 50 volts, making it suitable for a wide range of single-engine boats. For dual-engine systems, two switches are used, one per engine.\u003c\/p\u003e\u003cp\u003eThe switch offers a four-position OFF-NONE-ON-ON operation mode, giving the operator clear control over which battery bank is active at any time. It is rated for 250 amps continuous and 360 amps intermittent, covering the demands of typical marine electrical loads including starting and house circuits. The switch is ignition protected, so it is built to the standards required for installation in the engine compartments of gasoline powered boats. When used with non-unitized alternators, the switch interrupts the field current if turned OFF while the engine is running, reducing the risk of alternator damage.\u003c\/p\u003e\u003cp\u003eHoused in red plastic with a rotary knob actuator, the switch mounts to a panel and connects via clamp-style terminals sized to accept marine cable. Overall dimensions are 5-1\/2 inches in diameter by 2-5\/8 inches deep.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Perko\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 8501DP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Mode:\u003c\/strong\u003e OFF-NONE-ON-ON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Positions:\u003c\/strong\u003e 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 250 Amps continuous, 360 Amps intermittent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Voltage:\u003c\/strong\u003e 12, 24, and 32 Volt systems (under 50 volts)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition Protection:\u003c\/strong\u003e Ignition protected\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type:\u003c\/strong\u003e Rotary\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Panel mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal \/ Connector Type:\u003c\/strong\u003e Clamp, marine terminal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic housing, alloy steel contacts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Red\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIngress Protection Rating:\u003c\/strong\u003e IP54\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 5-1\/2 inches diameter x 2-5\/8 inches depth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.85 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Perko 8501DP used for?\u003c\/strong\u003e The Perko 8501DP is a battery selector switch used to choose between two or more batteries on a boat for starting, charging, or running both batteries together in parallel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat voltage systems does the 8501DP support?\u003c\/strong\u003e It is built for 12, 24, and 32 volt marine electrical systems, and is rated for use on systems under 50 volts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many amps can the 8501DP handle?\u003c\/strong\u003e 250 amps continuous and 360 amps intermittent, which covers typical starting and house circuit loads on a boat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Perko 8501DP safe to install in a gasoline engine room?\u003c\/strong\u003e Yes, the 8501DP is ignition protected, meaning it meets the standard required for installation in the engine rooms of gasoline powered boats.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need one switch or two for a dual-engine boat?\u003c\/strong\u003e For dual-engine systems, two 8501DP switches are used, one per engine, while a single switch covers a single-engine boat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat happens if I turn the 8501DP off while the engine is running?\u003c\/strong\u003e When used with non-unitized alternators, turning the 8501DP to OFF while the engine is running interrupts the alternator field current, reducing the risk of alternator damage.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the switch positions on the 8501DP?\u003c\/strong\u003e The 8501DP has four positions: OFF-NONE-ON-ON, allowing selection between battery banks or combined operation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the Perko 8501DP?\u003c\/strong\u003e The 8501DP measures 5-1\/2 inches in diameter by 2-5\/8 inches deep and weighs 0.85 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 8501DP switch made of?\u003c\/strong\u003e The 8501DP has a plastic housing with alloy steel contacts and a red rotary knob actuator.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the 8501DP mount and wire in?\u003c\/strong\u003e The 8501DP is a panel-mount switch with clamp-style terminals sized for marine cable connections.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Perko 8501DP?\u003c\/strong\u003e The 8501DP is finished in red, the standard color for this Perko battery selector switch.\u003c\/p\u003e","brand":"Perko","offers":[{"title":"Default Title","offer_id":48991122456795,"sku":"PKO-8501DP","price":76.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/PKO-8501DP_lg__23453.1558118344.500.750.jpg?v=1785188035","url":"https:\/\/www.goodvibesmarina.com\/products\/perko-8501dp-battery-selector-switch-250a-marine-dual-battery-switch-for-12-24-32v-systems-ignition-protected","provider":"Good Vibes Marina","version":"1.0","type":"link"}
