The 300mA sensitivity is intended for fault protection and fire risk duties rather than 30mA additional protection, often on TT supplies or upfront of a distribution board. RCDs give no overcurrent protection, so use them with suitably rated MCBs or upstream fuses.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e100A rated current\u003c\/li\u003e\n\u003cli\u003e300mA Type A sensitivity\u003c\/li\u003e\n\u003cli\u003e4P three phase and neutral switching\u003c\/li\u003e\n\u003cli\u003eTest button for regular functional checks\u003c\/li\u003e\n\u003cli\u003e35mm DIN rail mounting\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 RTA1003004\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct type:\u003c\/strong\u003e Type A RCD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated current:\u003c\/strong\u003e 100A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated residual current:\u003c\/strong\u003e 300mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCD type:\u003c\/strong\u003e Type A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 4P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e 35mm DIN rail\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard:\u003c\/strong\u003e BS EN 61008-1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSuitable for\u003c\/h2\u003e\u003cp\u003eThree phase distribution boards, TPN boards, commercial and industrial supplies.\u003c\/p\u003e","brand":"FuseBox Consumer Units \u0026 Circuit Protection","offers":[{"title":"Default Title","offer_id":55126986162522,"sku":"RTA1003004","price":35.41,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/6232\/6106\/files\/FuseBox-RTA1003004-100A-4-Pole-300mA-Type-A-RCD.jpg?v=1793799498","url":"https:\/\/account.alertelectrical.com\/products\/fusebox-100a-300ma-4p-type-a-rcd-rta1003004","provider":"Alert Electrical","version":"1.0","type":"link"}
