Engineered for the ultra-fast protection of critical power semiconductor devices, this Size 91 fuse is rated for 1500VAC and 315A. It is designed to provide ultimate protection for modern power conversion equipment such as SCRs, diodes, thyristors, GTOs, and IGBT devices.\u003c\/p\u003e\n\u003cp\u003eUtilizing the URH design architecture, this fuse features pure silver die-cut elements encapsulated in high-grade solidified sand. This construction provides superior control over arcing characteristics, resulting in low I²t clearing energy and a massive breaking capacity of 200kA. The contact surfaces are constructed from silver-plated brass, and all hardware is non-magnetic to ensure low power dissipation and high thermal efficiency. Each unit is equipped with a low-voltage striker\/trip-indicator, facilitating immediate local status identification and the option for remote signaling via a field-mountable microswitch.\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 ensures specialized high-speed Response for protecting sensitive semiconductor components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Interrupting Rating:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e200kA breaking capacity provides robust circuit protection under extreme fault conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnergy Efficiency:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eLow power dissipation (59W at rated current) minimizes energy loss and heat generation within enclosures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Indicating System:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIntegrated mechanical striker allows for easy visual verification and microswitch integration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial Standard Mounting:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eFlush end metric threads provide high-torque, low-resistance bolted connections.\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\u003ePC91UH15C315TF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eD076156\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Current (In):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e315A\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 (High-speed Semiconductor Protection)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBreaking Capacity (I1):\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\u003e384 kA²s\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Dissipation:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e59W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndication System:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIntegrated Striker\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\u003eCeramic\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 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":51772449259799,"sku":null,"price":700.0,"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-pc91uh15c315tf-protistor-high-speed-fuse-315a-1500vac-size-91-ar-square-body-flush-end-with-striker-d076156","provider":"Apexon Solutions LLC","version":"1.0","type":"link"}
