This is the current-production version — lifecycle status is active (cite:). The LSI protection (long-time, short-time, instantaneous) plus integrated earth-leakage (Class A) cover distribution feeders where selectivity and ground-fault detection are required on the same frame. ## Protection and metering in one package The trip unit integrates energy metering with an LCD display (cite:) and communicates maximeters, demand current/power, power quality, and time-stamped event tables (cite:). The long-time pickup Ir is adjustable 18...40 A (cite:); short-time delay tsd is adjustable 0...0.4 s with I²t on/off (cite:). Instantaneous pickup Ii is also adjustable (cite:). Neutral protection offers 3D+N/2, 4D, or 3D (no protection) (cite:). ## Integration notes The trip unit mounts in the fixed-mount ComPacT NSX100...250 frame (cite:). Neutral is on the left (cite:). IP40 front face (cite:) keeps tools and fingers out but is not washdown-rated. Operating temperature range is -25...70 °C (cite:); storage -40...85 °C (cite:).","metaTitle":"C1047A040 ComPacT NSX MicroLogic 7.2 E AL Trip Unit, 40 A, 4","metaDescription":"C1047A040 is a Schneider Electric ComPacT NSX trip unit with MicroLogic 7.2 E AL, rated 40 A at 40 °C, 4P, LSI protection, integrated earth-leakage.
