This Size 32 aR class fuse is engineered to provide reliable short-circuit protection for high-current applications including industrial rectifiers, large motor drives, and power converters where sensitive components like diodes and thyristors require exceptionally low I²t let-through energy.\u003c\/p\u003e\n\u003cp\u003eThe fuse features a high-grade ceramic body and silver-plated copper contacts for optimized electrical conductivity and thermal performance. It utilizes pure silver elements and high-purity sand filler to ensure a high breaking capacity of 200kA. For monitoring and maintenance, it comes equipped with a Type T mechanical striker, providing visual indication or integration with an optional microswitch for remote fault detection. The TTF flush-end M10 metric threaded construction allows for a direct, low-resistance 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\u003ePC32UD45V1800TF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eE302178\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1800A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e450V AC (IEC) \/ 500V AC (UL)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating (Breaking Capacity):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e200kA at 450V 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 (TTF)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndication System:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIntegrated Mechanical Striker (Type T)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePre-arcing I²t:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1900 kA²s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal Clearing I²t at Rated Voltage:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e6800 kA²s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Dissipation at Rated Current:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e200W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards Compliance:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIEC 60269-4, ASRE 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":51764239237399,"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-pc32ud55v1250tf-protistor-fuse-1250a-550v-ac-size-32-ar-high-speed-square-body-with-striker-pack-of-3-1213939818.png?v=1767247149","url":"https:\/\/www.apexonsupply.com\/products\/mersen-pc32ud45v1800tf-protistor-fuse-1800a-450v-ac-size-32-ar-high-speed-square-body-with-striker-pack-of-3","provider":"Apexon Solutions LLC","version":"1.0","type":"link"}
