As a 3-pole block it protects all three phases of a 3-phase MCB rather than the single-phase coverage of a 2-pole RCD block. Choose the 30 mA sensitivity version instead where direct-contact protection is the design requirement.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":50228998734107,"sku":"2CSB203001R3250","price":76.44,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/abb-2csb203001r3250-dda203-ac-25-0-3-rcd-block.jpg?v=1790959003","url":"https:\/\/stoklink.com\/products\/abb-2csb203001r3250-dda203-ac-25-0-3","provider":"Stoklink","version":"1.0","type":"link"}
