The fuse utilizes blade terminals with silver-plated construction for superior reliability in harsh environments. With a 200,000 AIC AC interrupting rating, the A4BY4000-55BA provides robust protection for high-amperage applications. The glass melamine body and unique Class L dimensions ensure one-way interchangeability and prevent replacement by other fuse classes.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAmperage Rating: 4000A\u003c\/li\u003e\n\u003cli\u003eVoltage Rating: 600VAC \/ 300VDC\u003c\/li\u003e\n\u003cli\u003eFuse Class: Class L\u003c\/li\u003e\n\u003cli\u003eTime Delay: 4 seconds minimum at 500% rating\u003c\/li\u003e\n\u003cli\u003eInterrupting Rating: 200,000 AIC AC\u003c\/li\u003e\n\u003cli\u003eTerminal Type: Blade with silver plating\u003c\/li\u003e\n\u003cli\u003eBody Material: Glass melamine\u003c\/li\u003e\n\u003cli\u003eDimensions: 5 3\/4 inches x 10 3\/4 inches\u003c\/li\u003e\n\u003cli\u003eWeight: 32 lbs\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: A4BY4000-55BA\u003c\/li\u003e                                             \u003cli\u003eManufacturer : Eaton\u003c\/li\u003e\n\u003cli\u003eBrand : Cutler Hammer\u003c\/li\u003e\n\u003cli\u003eCategory : Fuse\u003c\/li\u003e\n\u003cli\u003eItem Subcategory : Low Voltage Fuse\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 : 4000\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 : 782001938499\u003c\/li\u003e\n\u003cli\u003eGTIN : 00782001938499\u003c\/li\u003e\n\u003cli\u003eWeight : 11 \u003c\/li\u003e\n\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"Cutler Hammer","offers":[{"title":"New","offer_id":44587925995679,"sku":"A4BY4000-55BA-New","price":14178.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0500\/2349\/7887\/files\/A4BY4000.png?v=1758202883","url":"https:\/\/essentialparts.com\/products\/a4by4000-55ba-circuit-breaker-fuse-amp-trap","provider":"Essential Electric Supply","version":"1.0","type":"link"}
