The Schneider Electric LC1E0901Q7 is a 3-pole (3 NO) contactor from the Easy TeSys Control range, rated for AC-3 duty at 9 A up to 440 V with a 380 V AC coil. The AC-3 utilisation category means it is designed for starting and stopping squirrel-cage induction motors — the 9 A rating governs the motor full-load current it can switch, not the resistive heating current. For resistive loads (AC-1), the same contactor carries a higher current, but the AC-3 figure is the one that decides motor fit. The coil is 380 V AC, so the control circuit must supply that voltage. The contactor mounts on a plate or DIN rail, fitting a standard 45 mm wide slot in the enclosure. Operating altitude reaches 3000 m without derating, which covers most installations outside high-mountain sites.
The contactor carries compliance with EN/IEC 60947-1, 60947-4-1, and 60947-5-1, plus the Chinese GB/T equivalents. Fire resistance is tested to 850 °C per IEC 60695-2-1. Protective treatment is TH (pollution degree 3) per IEC 60068-2-30, meaning it withstands humid, tropical environments. The IP2X degree of protection means the contactor body is finger-safe but not sealed against dust or water — it belongs inside an enclosure, not on an open panel face.
