The Schneider Electric LC1E09004Q7IN is a 4-pole (4NO) contactor from the Easy TeSys Control range, rated for resistive loads in AC-1 utilisation category at 25 A up to 415 V. It mounts on a plate or DIN rail, with an IP2X degree of protection per IEC 60529. The part is now obsolete per the manufacturer.
What the AC-1 rating means for fit
The AC-1 rating (25 A at ≤415 V) means this contactor is designed for switching resistive loads — heaters, lighting banks, or resistive furnaces — where inrush current is low. It is not rated for motor starting (AC-3) or mixed inductive loads.
The LC1E09004Q7IN is marked obsolete by Schneider Electric. No official successor order code is listed in the manufacturer records.
The contactor complies with EN/IEC 60947-1, EN/IEC 60947-4-1, EN/IEC 60947-5-1, and the Chinese GB/T equivalents. It carries 850 °C fire resistance per IEC 60695-2-1 and TH protective treatment (pollution degree 3) per IEC 60068. Operating altitude is rated to 3000 m.
Physical integration
Dimensions are 45 mm wide, 74 mm high, 80 mm deep. The non-overlap time between NC and NO contacts is guaranteed at 1.5 ms on both energisation and de-energisation — relevant for interlocking circuits where contact overlap could cause a short.
