The 750 V DC rating is reached with all 3 poles wired in series; pick the 250 A rating to match the DC bus or PV array current, and choose a different sibling in the same TM-DC series for a higher or lower current without changing the 36 kA breaking capacity.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":50229508636955,"sku":"C40F3TM250D","price":952.82,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-c40f3tm250d.jpg?v=1790868808","url":"https:\/\/stoklink.com\/products\/schneider-electric-c40f3tm250d-compact-nsx250f-dc-mccb","provider":"Stoklink","version":"1.0","type":"link"}
