The LC1E32004M7IN is a 4-pole (4NO) contactor from Schneider Electric's Easy TeSys Control range, rated for AC-1 resistive loads up to 55 A at ≤415 V with a 220 V coil. It mounts on plate or DIN rail and carries compliance with EN/IEC 60947-1, -4-1, -5-1 and GB/T equivalents, plus 850 °C glow-wire resistance per IEC 60695-2-1 and IP2X finger protection.
The AC-1 utilisation category tells you this contactor is rated for resistive loads — heaters, incandescent lighting, or other loads with low inrush. It is not specified for AC-3 motor duty (inductive motor starting), so if your application involves switching motors, this is not the right part. The 55 A rating is the thermal current at ≤415 V in AC-1; for motor loads you would need a derated or different-rated device. The 4P (4NO) pole configuration means all four poles are normally open — no auxiliary NC contacts built in. If your circuit requires a normally closed feedback path, you will need to add an external auxiliary contact block. Operating altitude is rated to 3000 m without derating, and the protective treatment TH conforming to IEC 60068 indicates it is suitable for tropical/humid environments (pollution degree 3). The permissible ambient temperature range is -20 to 70 °C at the coil, with storage from -60 to 80 °C and operation from -5 to 55 °C. Mechanical robustness is specified for vibration (1.5 Gn open, 3 Gn closed, 5–300 Hz) and shock (6 Gn open, 10 Gn closed for 11 ms), making it suitable for industrial panels subject to moderate vibration.
The LC1E32004M7IN is obsolete per the product status.
