Choose it for the highest-current single-phase final circuits this frame size supports, since a higher load would require stepping up to a different frame rather than a higher B-curve rating.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSKU\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2CSS255101R0405\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\u003eSN201\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCatalog Designation\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSN201-B40\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eEAN\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e8012542091356\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\u003ePosition of Neutral Terminal\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRight\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTripping Characteristic\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eType B\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\u003e40 A\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 V (IEC 60898-1)\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 Ultimate Breaking Capacity (Icu)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e10 kA at 230 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated Short-Circuit Capacity (Icn)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e6 kA at 230 V\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\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\u003eDegree of Protection\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePollution Degree\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConnecting Capacity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFlexible 1-10 mm² \/ Rigid 1-16 mm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWidth\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e18 mm (1 module)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eNet Weight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e110 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eCertifications \u0026amp; Standards\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eIEC\/EN 60898-1\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eSelection Notes\u003c\/h2\u003e\u003cp\u003eAt the top of the SN201 range, the 40 A SN201-B40 still fits the same 1-module, 18 mm housing as the rest of the family, with no change to the type B curve's 3-5× In instantaneous trip band or the 6 kA breaking capacity at 230 V AC. This is the rating to choose when a single-phase resistive or lightly inductive circuit's load approaches the frame's current ceiling; beyond 40 A, a larger-frame device rather than a higher B-curve rating is needed. As with the rest of the range, avoid it on circuits with significant motor or transformer inrush.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":50229374091547,"sku":"2CSS255101R0405","price":22.2,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/abb-2css255101r0405-sn201-b40-mcb.png?v=1790959551","url":"https:\/\/stoklink.com\/products\/abb-2css255101r0405-sn201-b40","provider":"Stoklink","version":"1.0","type":"link"}
