This Size 32 aR class fuse is specifically engineered to provide superior short-circuit protection for high-power electronics such as rectifiers, inverters, and large motor drives. It is optimized to minimize I²t let-through energy, ensuring the protection of sensitive components like diodes, thyristors, and SCRs during fault conditions.\u003c\/p\u003e\n\u003cp\u003eConstructed with a premium ceramic body and silver-plated contact surfaces, this fuse ensures high breaking capacity and exceptional thermal stability. The internal silver elements are embedded in high-purity solidified sand to effectively quench arcs. This model features an integrated Type I mechanical striker, allowing for local visual trip indication or the triggering of a microswitch for remote fault signaling. The TTI flush-end M10 threaded interface ensures a low-inductance, secure bolted mounting directly to electrical busbars.\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\u003eA070UD32TTI550\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eN300438\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e550A\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\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\u003e45 kA²s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal Clearing I²t at Rated Voltage:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e315 kA²s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Dissipation at Rated Current:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e105W\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":51764240482583,"sku":null,"price":335.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/9210\/1655\/files\/ferraz-shawmut-general-industrial-fuses-mersen-a070ud32tti550-protistor-fuse-550a-700v-ac-size-32-ar-high-speed-square-body-with-striker-pack-of-3-1213939816.png?v=1767247056","url":"https:\/\/www.apexonsupply.com\/products\/mersen-a070ud32tti550-protistor-fuse-550a-700v-ac-size-32-ar-high-speed-square-body-with-striker-pack-of-3","provider":"Apexon Solutions LLC","version":"1.0","type":"link"}
