It is specifically engineered to provide state-of-the-art protection for power semiconductor devices, including SCRs, diodes, thyristors, GTOs, and IGBT devices. Rated for 1500VAC and 125A, this Size 91 fuse is optimal for high-demand power conversion equipment.\u003c\/p\u003e\n\u003cp\u003eDesigned with URF technical specifications, the fuse contains pure silver die-cut elements encapsulated in solidified sand. This configuration allows for precise control of arcing characteristics, ensuring a very low I²t clearing value and a massive breaking capacity of 200kA. The construction features silver-plated brass contact surfaces and non-magnetic hardware to ensure maximum conductivity and efficiency. Each unit comes equipped with a low-voltage striker\/trip-indicator, capable of triggering a field-mountable microswitch for real-time system monitoring.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltrafast Action:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eaR utilization category provides high-speed protection for sensitive semiconductor circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Interrupting Capacity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eRated at 200kA at 1500VAC, ensuring robust protection under severe fault conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePremium Materials:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ePure silver elements and ceramic body offer high thermal stability and reliability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Indication:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIncludes a mechanical striker for visual indication and remote signaling via microswitch.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow Power Loss:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eOptimized design results in a power dissipation of only 43W at rated current.\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\u003eBrand:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eMersen\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eProtistor® Size 91 aR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel\/Catalog No:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ePC91UF15C125TF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eX076150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Current:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e125A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Voltage:\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 (High-speed Semiconductor Protection)\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 Rated Voltage:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e15 kA²s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Dissipation:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e43W\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\u003eBody Material:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eHigh-grade Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e51mm (W) x 62mm (H) x 101mm (L)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIEC 60269-4\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":51772438774039,"sku":null,"price":520.0,"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-x076150-protistor-fuse-125a-1500v-ac-size-91-ar-square-body-flush-end-1pc","provider":"Apexon Solutions LLC","version":"1.0","type":"link"}
