Product details

The C1047A040 is a Schneider Electric MicroLogic 7.2 E AL electronic trip unit for the ComPacT NSX100...250 range, rated 40 A at 40 °C, 4 poles, and compliant with EN/IEC 60947-2. 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:).

Frequently asked questions

Where can I buy C1047A040 and how do I get a price?

The C1047A040 is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing.

What is the closest pin-compatible alternative to C1047A040 in this component family?

Within the ComPacT NSX100...250 range, the MicroLogic 7.2 E AL is the specific variant with integrated earth-leakage and LSI protection at 40 A. Other trip units in the same frame (e.g., MicroLogic 2.2, 5.2, 6.2) share the same physical footprint but differ in protection curves and metering features. No direct pin-compatible alternative with identical function exists.

What is C1047A040's listed range (ComPacT) on this component line?

The C1047A040 belongs to the ComPacT NSX100...250 range (cite:,).

What is C1047A040's listed standards (EN/IEC 60947-2) on this component line?

The C1047A040 complies with EN/IEC 60947-2 (cite:), the standard for low-voltage switchgear and controlgear.

What compliance documentation does this brand provide for C1047A040 (RoHS, REACH, UL, IEC)?

The C1047A040 carries EN/IEC 60947-2 certification (cite:). Electrical shock protection is Class II (cite:). The evidence does not list RoHS, REACH, or UL specific marks; check the manufacturer's declaration for those.
