This fuse features a 300kA interrupting rating, current-limiting design, and a 4-second time-delay characteristic to accommodate high inrush currents from motors and transformers without nuisance tripping. The Amp-Trap 2000® series provides superior protection for service entrance equipment and downstream components, with a rejection-style body to prevent incorrect replacement. \u003cul\u003e \u003cli\u003eAmperage Rating: 1800A\u003c\/li\u003e \u003cli\u003eVoltage Rating: 600V AC, 500V DC\u003c\/li\u003e \u003cli\u003eNumber of Poles: 1\u003c\/li\u003e \u003cli\u003eMounting Type: Bolted\u003c\/li\u003e \u003cli\u003eInterrupting Rating: 300kA\u003c\/li\u003e \u003cli\u003eSeries\/Frame: A4BQ\u003c\/li\u003e \u003cli\u003eFuse Type: Class L, Time-Delay\u003c\/li\u003e \u003cli\u003eResponse Time: 4-second time-delay at 500% rated current\u003c\/li\u003e \u003cli\u003eBody Material: Fiberglass\u003c\/li\u003e \u003cli\u003eUL Listed: UL 248-10\u003c\/li\u003e \u003cli\u003eCSA Certified: C22.2 No. 248.10\u003c\/li\u003e \u003cli\u003ePhysical Size: 3.5\" x 10.75\"\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: A4BQ1800\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\u003eSection  : Fuses\u003c\/li\u003e\n\u003cli\u003eFamily : Amp-Trap 2000\u003c\/li\u003e\n\u003cli\u003eType : A4BQ\u003c\/li\u003e\n\u003cli\u003eVoltage : 600\u003c\/li\u003e\n\u003cli\u003eAmperage : 1800\u003c\/li\u003e\n\u003cli\u003eAIC rating : 200kA@600V\u003c\/li\u003e\n\u003cli\u003eDiameter : 3.5\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 : 782001930127\u003c\/li\u003e\n\u003cli\u003eGTIN : 00782001930127\u003c\/li\u003e\n\u003cli\u003eWeight : 8 \u003c\/li\u003e\n\u003c\/ul\u003e                                         \u003cbr\u003e                                          ","brand":"Cutler Hammer","offers":[{"title":"New","offer_id":42301400613023,"sku":"A4BQ1800-New","price":843.85,"currency_code":"USD","in_stock":true},{"title":"Re-Certified","offer_id":42342448267423,"sku":"A4BQ1800-ReCert","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0500\/2349\/7887\/files\/A4BQ1800_0.jpg?v=1729680105","url":"https:\/\/essentialparts.com\/products\/a4bq1800-mersen-class-l-time-delay-fuse-1800a-600v-1-pole-300kair","provider":"Essential Electric Supply","version":"1.0","type":"link"}
