With a high rated current of 800A and a voltage rating of 700V AC, this Size 32 aR class fuse is ideal for demanding industrial applications such as high-power rectifiers, traction inverters, and large motor drives. It is engineered to provide superior peak current limitation and extremely low I²t (clearance energy), ensuring rapid circuit interruption to protect sensitive components like thyristors, GTOs, and IGBTs.\u003c\/p\u003e\n\u003cp\u003eThe fuse is constructed with a high-strength ceramic body and silver-plated copper KI-style bolted contacts (Metric Bolted Studs), offering low power loss and high resistance to mechanical vibration and thermal cycling. The internal silver elements and high-grade silica sand filling guarantee efficient arc quenching and a robust breaking capacity of 200kA. This model features an integrated Type K mechanical striker, providing a reliable physical trip indication that can also be used to actuate an external microswitch for remote fault detection.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eMersen\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eA070UD32KI800\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eN300197\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e800A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e700V AC (IEC \/ UL)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating (Breaking Capacity):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e200kA at 700V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Class:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eaR (Ultra-Fast Acting)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Size:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Configuration:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eKI (Metric Bolted Studs)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndication System:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIntegrated Mechanical Striker (K-Type)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePre-arcing I²t:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e165 kA²s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal Clearing I²t at Rated Voltage:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1100 kA²s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Dissipation at Rated Current:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e120W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards Compliance:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIEC 60269-4, UL 248-13 Recognized, RoHS Compliant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ePack of 3\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv data-version=\"2.2.5\" data-event=\"v2\" id=\"whale-data-ext\"\u003e\u003c\/div\u003e","brand":"Ferraz Shawmut","offers":[{"title":"Default Title","offer_id":47416752767255,"sku":"A070UD32KI800","price":450.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/9210\/1655\/files\/ferraz-shawmut-a070ud32ki800-3pcs-ferraz-shawmut-f300201-a070ud32ki800-fuses-1212531875.jpg?v=1766605690","url":"https:\/\/www.apexonsupply.com\/products\/ferraz-shawmut-f300201-a070ud32ki800-fuses","provider":"Apexon Solutions LLC","version":"1.0","type":"link"}
