Ics equals Icu across the full voltage range (90\/50\/50 kA), meaning the breaker is rated to clear its full ultimate fault current and remain in service afterward, not just survive a single trip. Below 125 A load the thermal setting can be trimmed down to 0.7 x In on the same unit.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":50229755019547,"sku":"C12N3TM125B","price":253.34,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-c12n3tm125b-nsxm160n-mccb.jpg?v=1790869577","url":"https:\/\/stoklink.com\/products\/schneider-electric-c12n3tm125b-compact-nsxm160n-mccb","provider":"Stoklink","version":"1.0","type":"link"}
