The LC1E50Q6 is a 3-pole contactor from the Schneider Easy TeSys Control range, rated for AC-3 and AC-3e duty at 50 A up to 440 V, with a 380 V AC 60 Hz coil. It's a motor-control contactor also rated for resistive loads under AC-1. The part is now listed as obsolete.
The AC-3 rating of 50 A is the motor-switching current — that's the figure that governs whether this contactor handles your induction motor load. AC-3e is the same duty but with an extended electrical life profile for frequent starts. The 380 V AC coil means it pulls in on a 380 V line-to-line or line-to-neutral signal at 60 Hz; don't try to swap in a 50 Hz coil without checking the dropout curve. Mounts on DIN rail or a backplate, so it fits standard panel layouts. Compliant with EN/IEC 60947-4-1 (the contactor standard for motor starters) and EN/IEC 60947-5-1 (control circuit devices).
