Everlink spring-clamp auxiliary connections and DIN-rail or plate mounting are built in. Its TM-D thermal-magnetic trip unit combines the LI protection set in one block: L is the overload (thermal) function, adjustable 0.7–1 × In, and I is the short-circuit (magnetic) function, fixed at 600 A — so no separate instantaneous relay is needed. Within the same NSXm 63B frame, pick the 50 A trip rating to match the protected circuit's full-load current — lower- and higher-current variants share the same breaking capacity and enclosure footprint.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":50229725004059,"sku":"C11B3TM050B","price":174.87,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-c11b3tm050b-nsxm-63b-mccb.jpg?v=1790868482","url":"https:\/\/stoklink.com\/products\/schneider-electric-c11b3tm050b-compact-nsxm63b-3p-50a-mccb","provider":"Stoklink","version":"1.0","type":"link"}
