It trips on overload and short-circuit like a standard MCB rated 7.5 kA (Icu), and additionally senses series, parallel and earth arc faults before they ignite.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCatalog Designation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eS-ARC1 B20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSKU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2CSA255901R9205\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eABB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSeries\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eArc Fault Detection Devices with Integrated Overcurrent Protection - AFDD+MCB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEAN\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e8012542749936\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1P+N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Current (In)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e20 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTripping Characteristic\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCurve B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Operational Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e230-240 V AC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Ultimate Short-Circuit Breaking Capacity (Icu)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e7.5 kA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Service Short-Circuit Breaking Capacity (Ics)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6 kA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Insulation Voltage (Ui)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e500 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Impulse Withstand Voltage (Uimp)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4 kV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Frequency (f)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e50 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower Loss (Total)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3.6 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOvervoltage Category\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIII\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEnergy Limiting Class\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNumber of Modules\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2 (35 mm width)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTerminal Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eScrew Terminals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConnecting Capacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRigid 1-25 mm² \/ Flexible 1-16 mm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDegree of Protection\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTerminals IP20 \/ Housing IP40\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAmbient Air Temperature (Operation)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-25 to +55 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMounting Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDIN-Rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNet Weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.18 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eCertifications \u0026amp; Standards\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIEC\/EN 62606\u003c\/li\u003e\n\u003cli\u003eIEC\/EN 60898-1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSelection Notes\u003c\/h2\u003e\u003cp\u003eA 20 A rating extends the S-ARC1 range to heavier socket circuits and small fixed loads above what the 16 A unit can carry continuously. The curve-B instantaneous trip at 3-5x In still assumes a mainly resistive or lightly inductive load profile rather than motor inrush. Power dissipation rises to 3.6 W at this rating, worth checking against enclosure ventilation when several S-ARC1 units are stacked on one DIN rail.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":50229009285403,"sku":"2CSA255901R9205","price":155.47,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/abb-2csa255901r9205-s-arc1-b20-afdd.jpg?v=1790958157","url":"https:\/\/stoklink.com\/products\/abb-2csa255901r9205-s-arc1-b20","provider":"Stoklink","version":"1.0","type":"link"}
