The fuse is constructed with a melamine body and silver-plated copper alloy caps, designed in traditional North American bolted-style package with universal mounting options for direct bus-bar or stud mount installation. It delivers fast and reliable short-circuit protection while extending component longevity and reducing equipment-damaging heat energy.\u003cul\u003e\n\u003cli\u003eAmperage Rating: 300 A\u003c\/li\u003e\n\u003cli\u003eVoltage Rating: 500 V AC \/ 500 V DC\u003c\/li\u003e\n\u003cli\u003eInterrupting Rating: 200 kA AC \/ 50 kA DC\u003c\/li\u003e\n\u003cli\u003eFuse Type: Very-Fast-Acting High-Speed\u003c\/li\u003e\n\u003cli\u003eBody Material: Melamine\u003c\/li\u003e\n\u003cli\u003eTermination: Bolt Down (M8 Stud, 5\/16 inch)\u003c\/li\u003e\n\u003cli\u003eTime Constant: 10 ms\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -55 degrees C to +125 degrees C\u003c\/li\u003e\n\u003cli\u003eCertifications: UL 248-13, UL Recognized (E71611), c-UR-us\u003c\/li\u003e\n\u003cli\u003eEnvironmental Compliance: RoHS Compliant, REACH, Halogen Free\u003c\/li\u003e\n\u003cli\u003ePhysical Size: 38.1 mm x 110.31 mm\u003c\/li\u003e\n\u003cli\u003eCountry of Origin: Mexico\u003c\/li\u003e\n\u003c\/ul\u003eAt \u003cb\u003eEssential Parts\u003c\/b\u003e, we offer \u003cb\u003efast shipping\u003c\/b\u003e, \u003cb\u003elowest price\u003c\/b\u003e, and \u003cb\u003eexpert support\u003c\/b\u003e to help you get the right product every time. \t\t\t\t\t\t\t\t\t\t\u003cbr\u003e                                          \t\t\t\t\t\t\t\t\t\t\u003ch3\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003c\/h3\u003e \t\t\t\t\t\t\t\t\t\t\u003cul\u003e \t\t\t\t\t\t\t\t\t\t\t\u003cli\u003ePart Number: L50QS300\u003c\/li\u003e                                             \u003cli\u003eManufacturer : Littelfuse\u003c\/li\u003e\n\u003cli\u003eBrand : Littelfuse\u003c\/li\u003e\n\u003cli\u003eCategory : Fuse\u003c\/li\u003e\n\u003cli\u003eItem Subcategory : Low Voltage Fuse\u003c\/li\u003e\n\u003cli\u003eFamily : L50QS Series – High-Speed Semiconductor Fuse, Round Body\u003c\/li\u003e\n\u003cli\u003eType : L50QS Series – High-Speed Semiconductor Fuse, Round Body\u003c\/li\u003e\n\u003cli\u003eVoltage : 500\u003c\/li\u003e\n\u003cli\u003eAmperage : 300\u003c\/li\u003e\n\u003cli\u003eAIC rating : 200kA@500V\u003c\/li\u003e\n\u003cli\u003eDiameter : 1.22\u003c\/li\u003e\n\u003cli\u003eBarrels : 1\u003c\/li\u003e \t\t\t\t\t\t\t\t\t\t\u003c\/ul\u003e                                         \u003cbr\u003e                                         \u003ch3\u003e\u003cb\u003eProduct Data\u003c\/b\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eUPC : 079458860061\u003c\/li\u003e\n\u003cli\u003eDimensions : x 4-11\/32 in x\u003c\/li\u003e\n\u003cli\u003eWeight : 1 \u003c\/li\u003e\n\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"Littelfuse","offers":[{"title":"New","offer_id":62566732103839,"sku":"L50QS300-New","price":100.94,"currency_code":"USD","in_stock":true}],"url":"https:\/\/essentialparts.com\/products\/l50qs300","provider":"Essential Electric Supply","version":"1.0","type":"link"}
