This fuse provides reliable circuit protection with a 4-second minimum time delay at 500% rating, allowing it to withstand normal current surges while coordinating with ground fault relays. The A4BY801 features a glass melamine body and plated terminals for superior reliability in harsh environments. Its unique dimensions prevent replacement by other fuse classes, and blade-stamped catalog numbers ensure permanent identification. This fuse is current limiting and suitable for mains, feeders, circuit breakers, load centers, panelboards, switchboards, and metering centers. \u003cul\u003e \u003cli\u003ePart Number: A4BY801\u003c\/li\u003e \u003cli\u003eManufacturer: Mersen Ferraz Shawmut\u003c\/li\u003e \u003cli\u003eAmperage: 801A\u003c\/li\u003e \u003cli\u003eVoltage: 600V AC, 300V DC\u003c\/li\u003e \u003cli\u003eNumber of Poles: 1\u003c\/li\u003e \u003cli\u003eMounting Type: Bolted\u003c\/li\u003e \u003cli\u003eInterrupt Rating: 200,000 AIC (AC), 100,000 AIC (DC)\u003c\/li\u003e \u003cli\u003eSeries\/Frame: A4BY\u003c\/li\u003e \u003cli\u003eSpeed: Time Delay\u003c\/li\u003e \u003cli\u003eCurrent Limiting: Yes\u003c\/li\u003e \u003cli\u003eCertifications: UL Listed, CSA Certified\u003c\/li\u003e \u003cli\u003ePhysical Size: 2 1\/2\" x 10 3\/4\"\u003c\/li\u003e \u003c\/ul\u003e At \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: A4BY801\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 : AKR Series\u003c\/li\u003e\n\u003cli\u003eType : A4BY\u003c\/li\u003e\n\u003cli\u003eVoltage : 600\u003c\/li\u003e\n\u003cli\u003eAmperage : 801\u003c\/li\u003e\n\u003cli\u003eAIC rating : 200kA@600V\u003c\/li\u003e\n\u003cli\u003eDiameter : 2.5\u003c\/li\u003e\n\u003cli\u003eClass Rating : L\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 : 782001939120\u003c\/li\u003e\n\u003cli\u003eGTIN : 00782001939120\u003c\/li\u003e\n\u003cli\u003eWeight : 5 \u003c\/li\u003e\n\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"Cutler Hammer","offers":[{"title":"New","offer_id":42301396451487,"sku":"A4BY801-New","price":666.56,"currency_code":"USD","in_stock":true},{"title":"Re-Certified","offer_id":42345404301471,"sku":"A4BY801-ReCert","price":566.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0500\/2349\/7887\/files\/A4BY801_0.jpg?v=1724975786","url":"https:\/\/essentialparts.com\/products\/a4by801-mersen-ferraz-shawmut-801a-600v-class-l-time-delay-fuse-1-pole","provider":"Essential Electric Supply","version":"1.0","type":"link"}
