This Size 91 fuse is specifically designed for 1500VAC applications with a rated current of 225A, making it an essential component for modern power conversion equipment including SCRs, diodes, thyristors, GTOs, and IGBTs.\u003c\/p\u003e\n\u003cp\u003eConstructed with the URK design specification, the fuse features pure silver die-cut elements encapsulated in high-stability solidified sand. This internal architecture provides precise control over arcing characteristics, ensuring high breaking capacity (200kA) and low I²t values to minimize downstream damage during fault conditions. The unit is built with silver-plated brass contact surfaces and non-magnetic materials to maintain high electrical efficiency. For operational monitoring, it includes an integrated mechanical striker (trip-indicator) that can trigger a field-mountable microswitch for remote fault detection.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSemiconductor Grade Protection:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eaR utilization category optimized for high-speed clearing of fault currents.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtreme Breaking Capacity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eRated for 200kA at 1500VAC, providing robust protection in high-power industrial circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Internal Design:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eFeatures silver die-cut elements and a ceramic body for superior thermal and electrical stability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStatus Indication:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eEquipped with a built-in striker to provide immediate visual confirmation and optional remote signaling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlush End Mounting:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eMetric thread flush ends ensure a secure, low-resistance bolted connection.\u003c\/li\u003e\n\u003c\/ul\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\u003ePC91UK15C225TF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eB076154\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Current (In):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e225A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Voltage (Un):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1500VAC (IEC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUtilization Category:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eaR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBreaking Capacity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e200kA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearing I²t (at 1500V):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e78 kA²s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Dissipation:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e58.5W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndication:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eStriker System\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Type:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eFlush ends (Metric threads)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSize 91\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCeramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTotal Weight:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e0.789 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards Compliance:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIEC 60269-4\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv id=\"whale-data-ext\" data-event=\"v2\" data-version=\"2.2.5\"\u003e\u003c\/div\u003e","brand":"Ferraz Shawmut","offers":[{"title":"Default Title","offer_id":51772446507287,"sku":null,"price":650.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/9210\/1655\/files\/ferraz-shawmut-general-industrial-fuses-mersen-pc91uf15c100tf-protistor-high-speed-fuse-100a-1500vac-size-91-ar-square-body-flush-end-with-striker-w076149-1214163085.png?v=1767520449","url":"https:\/\/www.apexonsupply.com\/products\/mersen-pc91uk15c225tf-protistor-high-speed-fuse-225a-1500vac-size-91-ar-square-body-flush-end-with-striker-b076154","provider":"Apexon Solutions LLC","version":"1.0","type":"link"}
