The trip unit provides L (long-time overload), So (short-time short-circuit with fixed delay), and I (instantaneous short-circuit) protection, which gives you adjustable overload curves and selective coordination downstream. The 36 kA Icu at 380/415 V AC is the interrupting rating that matters for most European 400 V distribution panels — it tells you the breaker can safely clear a fault up to 36 kA without welding contacts or rupturing the case. ## Compliance and approvals Overvoltage category III covers fixed-installation distribution boards. The IK07 impact rating confirms the enclosure withstands 2 J impacts — enough for accidental tool drops during maintenance. No RoHS or REACH declaration is in this evidence, but Schneider typically provides compliance documentation on request.","metaTitle":"Schneider Electric C10F42D040 ComPacT NSX100F MCCB, 40 A, 36","metaDescription":"Schneider Electric C10F42D040 ComPacT NSX100F MCCB, 40 A rated, MicroLogic 2.2 electronic trip unit, 36 kA at 415 V AC.
