use it where short-circuit and short-time protection is wanted ahead of a motor starter that already has its own overload device. At 70 kA Icu, the H-frame breaking capacity sets how close to the transformer the breaker can sit; choose the 2.3 M sibling in the same frame when the opposite combination of built-in overload and trip-class control is needed.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":50229668217115,"sku":"C40H31M320","price":904.01,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-c40h31m320.jpg?v=1790868863","url":"https:\/\/stoklink.com\/products\/schneider-electric-c40h31m320-compact-nsx400h-mccb","provider":"Stoklink","version":"1.0","type":"link"}
