The A4BY3000-55AK is a 100% rated device suitable for continuous currents up to its ampere rating. Its unique Class L dimensions prevent replacement by other fuse classes, and blade-stamped catalog numbers provide permanent identification. The glass melamine body and silver-plated copper terminals deliver superior reliability in harsh environments.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAmperage Rating: 3000A\u003c\/li\u003e\n\u003cli\u003eAC Voltage Rating: 600VAC\u003c\/li\u003e\n\u003cli\u003eDC Voltage Rating: 300VDC\u003c\/li\u003e\n\u003cli\u003eFuse Class: UL Class L\u003c\/li\u003e\n\u003cli\u003eResponse Time: Time Delay (4-second minimum)\u003c\/li\u003e\n\u003cli\u003eAC Interrupting Rating: 200,000 AIC\u003c\/li\u003e\n\u003cli\u003eDC Interrupting Rating: 100,000 AIC\u003c\/li\u003e\n\u003cli\u003eMounting Type: Bolted Blade\u003c\/li\u003e\n\u003cli\u003ePhysical Size: 5 inches x 10.75 inches\u003c\/li\u003e\n\u003cli\u003eBody Material: Glass Melamine\u003c\/li\u003e\n\u003cli\u003eTerminal Material: Silver-Plated Copper\u003c\/li\u003e\n\u003cli\u003eUL Listed to Standard 248-10 (601-6000A)\u003c\/li\u003e\n\u003cli\u003eCSA Certified to Standard C22.2 No. 248.10\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\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.\u003c\/p\u003e \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: A4BY3000-55AK\u003c\/li\u003e                                             \u003cli\u003eManufacturer : Mersen\u003c\/li\u003e\n\u003cli\u003eBrand : Ferraz Shawmut\u003c\/li\u003e\n\u003cli\u003eCategory : Fuse\u003c\/li\u003e\n\u003cli\u003eItem Subcategory : Fuse Part\u003c\/li\u003e\n\u003cli\u003eFamily : Amp-Trap\u003c\/li\u003e\n\u003cli\u003eType : A4BY\u003c\/li\u003e\n\u003cli\u003eVoltage : 600\u003c\/li\u003e\n\u003cli\u003eAmperage : 3000\u003c\/li\u003e\n\u003cli\u003eAIC rating : 200kA@600V\u003c\/li\u003e\n\u003cli\u003eConnection : Bolt-In\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 : 78200193839\u003c\/li\u003e\n\u003cli\u003eGTIN : 00782001938390\u003c\/li\u003e\n\u003cli\u003eWeight : 0.15 \u003c\/li\u003e\n\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"Ferraz Shawmut","offers":[{"title":"New","offer_id":45030993526943,"sku":"A4BY3000-55AK-New","price":0.0,"currency_code":"USD","in_stock":false},{"title":"Re-Certified","offer_id":45031204946079,"sku":"A4BY3000-55AK-ReCert","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0500\/2349\/7887\/files\/ferraz-shawmut-fuse-new-a4by3000-55ak-mersen-class-l-time-delay-fuse-3000a-600vac-300vdc-53693798875295.png?v=1766010164","url":"https:\/\/essentialparts.com\/products\/a4by3000-55ak-mersen-class-l-time-delay-fuse-3000a-600vac-300vdc","provider":"Essential Electric Supply","version":"1.0","type":"link"}
