It ships without a trip unit, so the installer selects and fits a separate DC-rated trip block to match the load. The frame carries IEC 60947-2 certification and an IP40 front face.","metaTitle":"Schneider LV438203 Compact NSX250F DC basic frame, 250 A, 36 kA","metaDescription":"Schneider LV438203 ComPact NSX250F DC basic frame: 250 A, 36 kA at 750 V DC, 3 poles, IEC 60947-2, without trip unit.
