It is rated 40 A at 40 °C (Ir adjustable 18...40 A) and provides LSIG protection — long-time (L), short-time (S), instantaneous (I), and ground-fault (G) — per EN/IEC 60947-2. The 4-pole unit (4P) is designed for distribution applications on 50/60 Hz networks up to 690 V AC. ## Protection coordination and selectivity LSIG protection covers the full fault spectrum: L (long-time) adjustable 15...400 s at 1.5×Ir, S (short-time) adjustable 0...0.4 s with I²t on/off, I (instantaneous) adjustable, and G (ground-fault) adjustable. Zone selective interlocking (ZSI) is built in — this lets multiple breakers in a cascade communicate fault direction, reducing trip time on a downstream fault while maintaining selectivity upstream. For a site electrical engineer coordinating a distribution panel, ZSI means you can set tighter short-time delays without losing coordination. Neutral protection is configurable: 0.5×Ir (3D+N/2), 1×Ir (4D), 1.6×Ir (3D+OSN), or no protection (3D). This covers both fully rated and reduced-neutral distribution schemes. The trip unit mounts into a ComPacT NSX100...250 fixed-mount breaker. The 4-pole unit occupies the left neutral position. IP40 front protection (IEC 60529) keeps tools and fingers out but is not sealed against washdown. Communication data includes energy metering, protection and alarm settings, time-stamped event tables, instantaneous and demand values, maintenance indicators, and power quality metrics. The LCD display shows local readouts without needing a connected controller.","metaTitle":"Schneider Electric C1046E040 MicroLogic 6.2 E Trip Unit, 40","metaDescription":"Schneider Electric C1046E040 MicroLogic 6.2 E electronic trip unit for ComPacT NSX. 40 A at 40 °C, LSIG protection, IEC 60947-2.
