This Size 32 aR category fuse is engineered for extreme industrial applications involving high-current power conversion, such as large motor drives, heavy-duty rectifiers, and high-capacity traction substations. It is specifically designed to provide superior protection by limiting I²t let-through energy to extremely low levels, preventing thermal damage to power semiconductors like diodes, thyristors, and GTOs.\u003c\/p\u003e\n\u003cp\u003eBuilt with a high-grade ceramic body for maximum thermal resistance and silver-plated copper mounting terminals for enhanced conductivity, this fuse ensures long-term operational reliability. The internal pure silver elements combined with high-purity sand facilitate efficient arc quenching and a high breaking capacity of 200kA. This model features an integrated Type I mechanical striker, allowing for local visual confirmation of a fuse trip and enabling remote monitoring via an optional auxiliary microswitch. The TTI flush-end M10 metric threaded interface provides a secure, low-loss bolted connection to industrial busbar systems.\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\u003eA060UD32TTI1250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eW300445\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1250A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e600V AC (IEC \/ UL)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating (Breaking Capacity):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e200kA at 600V 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\u003eFlush-End M10 Metric Threads (TTI)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndication System:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIntegrated Mechanical Striker (Type I)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePre-arcing I²t:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e580 kA²s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal Clearing I²t at Rated Voltage:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e3700 kA²s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Dissipation at Rated Current:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e195W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards Compliance:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIEC 60269-4, UL 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\u003c\/div\u003e\n\u003c\/div\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":51764242972951,"sku":null,"price":345.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/9210\/1655\/files\/ferraz-shawmut-general-industrial-fuses-mersen-a060ud32tti1250-protistor-fuse-1250a-600v-ac-size-32-ar-high-speed-square-body-with-striker-pack-of-3-1213939809.png?v=1767246878","url":"https:\/\/www.apexonsupply.com\/products\/mersen-a060ud32tti1250-protistor-fuse-1250a-600v-ac-size-32-ar-high-speed-square-body-with-striker-pack-of-3","provider":"Apexon Solutions LLC","version":"1.0","type":"link"}
