This Size 91 fuse is designed for 1500VAC applications with a 250A rating, providing ultimate protection for critical power conversion equipment such as SCRs, diodes, thyristors, GTOs, and IGBTs.\u003c\/p\u003e\n\u003cp\u003eConstructed following the URH design specification, the fuse features pure silver die-cut elements embedded in solidified sand. This technology ensures precise control of arcing characteristics, facilitating extremely low I²t clearing values and a very high breaking capacity of 200kA. The contact surfaces are silver-plated brass with non-magnetic hardware to ensure high conductivity and thermal stability. The fuse is equipped with a low-voltage striker system, serving as a mechanical trip-indicator that can operate a field-mountable microswitch for remote 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 Semiconductor Protection:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eaR characteristic provides high-speed response to protect sensitive power electronics.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Interrupting Rating:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eRated for 200kA at 1500VAC, ideal for protecting high-energy industrial circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow Energy Let-Through:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eOptimized for low I²t to minimize stress on downstream components during faults.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Indication:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIncludes a mechanical striker for immediate visual status and remote signaling compatibility.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eBuilt with a ceramic body and silver-plated terminals for reliable performance in demanding environments.\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\u003eSeries:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eProtistor® Size 91 aR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ePC91UH15C250TF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eC076155\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Current:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e250A\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\u003e246 kA²s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Dissipation:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e47W\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 Compliance:\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":51772446900503,"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-pc91uh15c250tf-protistor-high-speed-fuse-250a-1500vac-size-91-ar-square-body-flush-end-with-striker-c076155","provider":"Apexon Solutions LLC","version":"1.0","type":"link"}
