Turning the red textured knob connects or disconnects the circuit, letting you isolate the battery bank for maintenance, winter storage, or general safety when the boat is not in use. The textured knob and face are designed so the switch can be operated by feel in low light conditions.\u003c\/p\u003e\u003cp\u003eConstruction is a durable plastic housing rated IP66 for protection against dust and heavy seas or wash-down water, and the switch carries a 350 amp continuous current rating at 48 volts DC. Terminal studs are tinned copper to resist corrosion in a marine environment and are designed to accept multiple cable connections for secure, low resistance contact. The switch supports both surface mounting and rear panel mounting, giving installers flexibility in tight helm or engine room spaces.\u003c\/p\u003e\u003cp\u003eThis is a single circuit switch only, controlling one isolated battery bank; it does not combine circuits and does not include an alternator field disconnect. Overall dimensions are 2.9 x 6.38 x 8.63 inches and the switch weighs 1.3 pounds.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Blue Sea Systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 9003E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Battery Switch 'E' On-Off\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type:\u003c\/strong\u003e Rotary, Single Circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Mode:\u003c\/strong\u003e ON-OFF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Positions:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 350 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Voltage:\u003c\/strong\u003e 48 Volts DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Material:\u003c\/strong\u003e Tinned Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Red\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Panel Mount or Surface Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIngress Protection Rating:\u003c\/strong\u003e IP66\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 2.9 x 6.38 x 8.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Limited Lifetime Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Blue Sea Systems 9003E battery switch do?\u003c\/strong\u003e The 9003E is a single circuit ON-OFF rotary switch that turns one battery bank on or off, letting you isolate that circuit for maintenance or storage.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the current and voltage rating of the 9003E?\u003c\/strong\u003e The 9003E is rated for 350 amps at 48 volts DC.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 9003E control two separate battery banks?\u003c\/strong\u003e No. The 9003E is a single circuit switch that controls only one isolated battery bank; it does not combine circuits.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 9003E include an alternator field disconnect?\u003c\/strong\u003e No, this model of the Blue Sea Systems 9003E switch does not include an alternator field disconnect.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the 9003E battery switch mounted?\u003c\/strong\u003e The 9003E supports both surface mounting and rear panel mounting, allowing flexible placement in tight installation spaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 9003E switch made of?\u003c\/strong\u003e The housing is plastic, and the terminal studs are tinned copper for corrosion resistance and secure cable connections.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions and weight of the 9003E?\u003c\/strong\u003e The 9003E measures 2.9 x 6.38 x 8.63 inches and weighs 1.3 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 9003E rated for water or dust exposure?\u003c\/strong\u003e Yes, the 9003E carries an IP66 ingress protection rating, suitable for wet marine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 9003E battery switch?\u003c\/strong\u003e The 9003E is red with a textured knob and face designed to be operated by feel in low light.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat warranty comes with the 9003E?\u003c\/strong\u003e Blue Sea Systems backs the 9003E with a limited lifetime warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many terminal connections does the 9003E support?\u003c\/strong\u003e The tinned copper terminal studs on the 9003E are designed to accept multiple cable connections for secure, low resistance contact.\u003c\/p\u003e","brand":"Blue Sea Systems","offers":[{"title":"Default Title","offer_id":48989523083483,"sku":"BSS-9003E","price":52.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/bss-9003e_lg__92604.1558139646.500.750.jpg?v=1785329072","url":"https:\/\/www.goodvibesmarina.com\/products\/blue-sea-systems-9003e-e-series-battery-switch-single-circuit-on-off-350a-48v-dc","provider":"Good Vibes Marina","version":"1.0","type":"link"}
