As part of Mersen’s next-generation evolution in power electronics protection, this North American style round-body fuse is rated for 50A at 1000VDC. It is an ideal safety solution for high-power conversion applications, including Electric Vehicle (EV) fast-charging stations, Energy Storage Systems (ESS), and industrial battery management units.\u003c\/p\u003e\n\u003cp\u003eThis \"aR\" utilization category fuse is optimized to minimize thermal energy let-through (I²t) and peak let-through current, effectively shielding sensitive semiconductor components and DC busbars from the catastrophic effects of short-circuit faults. The D100QS series offers superior cycling ability compared to standard general-purpose fuses, ensuring reliable operation under high cyclic loading conditions. The \"-4\" designation indicates a standard bolt-on configuration, while the \"-4Y\" variant is specifically designated for metric screw mounting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized DC Performance:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSpecifically designed for DC systems up to 1000VDC with extremely fast clearing times.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior Cycling Ability:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eBuilt to provide a long, reliable service life even in environments with frequent load cycling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Breaking Capacity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eFeatures an interrupting rating of 100kA, ensuring maximum safety and arc quenching during high-energy faults.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow Power Dissipation:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDesigned with low watts loss to maximize energy efficiency and minimize heat generation within enclosures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRobust Construction:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eEngineered to withstand vibration and environmental stress, meeting industrial standards for heavy-duty applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Compliance:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eUL Recognized Component and REACH\/RoHS compliant.\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\u003eAmp-Trap® D100QS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eD100QS50-4 \/ D100QS50-4Y\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Current (In):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e50 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Voltage:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1000 VDC\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 (IR):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e100 kA @ 1000VDC (L\/R ≤ 1ms)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Breaking Capacity (MBC):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e\u0026lt; 3 kA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eRound Body with Center Bolting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e5 pieces per pack\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":51772620472599,"sku":null,"price":200.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/9210\/1655\/files\/ferraz-shawmut-general-industrial-fuses-mersen-d100qs50-4-amp-trap-high-speed-fuse-50a-1000vdc-ar-utilization-north-american-round-body-pack-of-5-1214168204.png?v=1767542049","url":"https:\/\/www.apexonsupply.com\/products\/mersen-d100qs50-4-amp-trap-high-speed-fuse-50a-1000vdc-ar-utilization-north-american-round-body-pack-of-5","provider":"Apexon Solutions LLC","version":"1.0","type":"link"}
