The 100 kA breaking capacity stays constant from 24 V DC up to 750 V DC because the poles connect in series for the higher-voltage ratings — the series 3-pole connection is what delivers the full 100 kA at 750 V DC. Choose the 400 A rating over the other TM-DC variants in the same frame to match the DC feeder or string combiner current.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":50229509816603,"sku":"C40S3TM400D","price":1161.93,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-c40s3tm400d-nsx400s-dc-dc-moulded-case-circuit-breaker.jpg?v=1790868724","url":"https:\/\/stoklink.com\/products\/schneider-electric-c40s3tm400d","provider":"Stoklink","version":"1.0","type":"link"}
