It ships without a trip unit, so you add the appropriate electronic or thermal-magnetic trip module to match your load's protection curve. The 36 kA breaking capacity at 415 V AC (Icu per IEC 60947-2) means it can safely interrupt fault currents up to that level without welding or rupturing, which is the figure you'll use for panel SCCR coordination at typical 400 V-class industrial voltages. The 85 kA at 240 V AC per UL 508 gives you headroom for 240 V distribution panels where fault current can run high, common in North American commercial and light industrial installations. Fixed-mount on a backplate, 140 mm wide × 255 mm high × 110 mm deep. Front connections top and bottom, with a 45 mm connection pitch that matches standard busbar and cable lug spacing. Toggle handle for manual switching and trip indication. IK07 impact rating handles the occasional tool bump during commissioning.","metaTitle":"Schneider Electric C40F3 ComPacT NSX400F 400A Basic Frame, 3","metaDescription":"Schneider Electric C40F3 ComPacT NSX400F basic frame, 400A frame rating, 36kA at 415VAC, 3 poles.

The closest sibling would be a similar frame size with a different breaking capacity code (e.g., the H or L versions for higher Icu at 415 V), or the same frame with an integrated trip unit (NSX400F with TM or Micrologic). The decision hinges on whether you need the bare frame for a custom trip module or a pre-configured breaker."},{"question":"What compliance documentation does Schneider provide for the C40F3?","answer":"Schneider provides declarations of conformity covering RoHS, REACH, CE, UKCA, and the applicable standards (EN/IEC 60947-2, UL 60947-4-1).
