BS 7671 recommends AFDDs for final circuits supplying socket outlets up to 32A, and they are commonly specified in sleeping accommodation, HMOs and buildings of combustible construction. The MAFDD104030B fits all FuseBox consumer units and TPN boards and can replace a FuseBox RCBO where arc protection is needed. At 40A it is typically used on cookers, electric showers and EV charger supplies. Final device selection should always follow the circuit design, cable size, installation method and fault level of the installation.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSeries and parallel arc fault detection\u003c\/li\u003e\n\u003cli\u003e40A B curve overcurrent protection\u003c\/li\u003e\n\u003cli\u003e30mA Type A residual current protection\u003c\/li\u003e\n\u003cli\u003e10kA breaking capacity\u003c\/li\u003e\n\u003cli\u003e1P+N with switched neutral\u003c\/li\u003e\n\u003cli\u003eLED fault indication\u003c\/li\u003e\n\u003cli\u003eCompact single module mini format\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e FuseBox\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct code:\u003c\/strong\u003e MAFDD104030B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct type:\u003c\/strong\u003e Mini AFDD RCBO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated current:\u003c\/strong\u003e 40A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTripping characteristic:\u003c\/strong\u003e B Curve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCD type:\u003c\/strong\u003e Type A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated residual current:\u003c\/strong\u003e 30mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBreaking capacity:\u003c\/strong\u003e 10kA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e 1P+N switched\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFault indication:\u003c\/strong\u003e LED\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e 35mm DIN rail\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards:\u003c\/strong\u003e BS EN 62606, BS EN 61009-1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSuitable for\u003c\/h2\u003e\u003cp\u003eCommercial installations, TPN boards and higher fault level supplies, socket circuits, bedrooms, HMOs, care settings and properties with timber frame construction.\u003c\/p\u003e","brand":"FuseBox Consumer Units \u0026 Circuit Protection","offers":[{"title":"Default Title","offer_id":55127040983386,"sku":"MAFDD104030B","price":133.06,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/6232\/6106\/files\/FuseBox-Mini-Arc-Fault-Detection-Devices-30mA-6kA_7e9b7485-0157-4dcc-a81f-7f3ccf831573.jpg?v=1793799680","url":"https:\/\/account.alertelectrical.com\/products\/fusebox-40a-30ma-type-a-b-curve-10ka-mini-afdd-rcbo-mafdd104030b","provider":"Alert Electrical","version":"1.0","type":"link"}
