The LC1E1201N5WB is a 3-pole contactor from the Schneider Electric Easy TeSys Control range, rated for AC-3 and AC-3e duty at 12 A up to 440 V, with a 415 V AC 50 Hz wide-range coil and one normally-closed auxiliary contact. The AC-3 rating means it is sized for switching squirrel-cage motors — the 12 A figure governs the motor full-load current it can handle, not the resistive load curve. For resistive loads (AC-1), the contactor can carry a higher current, but the AC-3 number is the one that decides motor fit.
Operating altitude goes to 3000 m without derating.
Designed to EN/IEC 60947-1, -4-1, and -5-1, plus the Chinese GB/T equivalents, and EN/IEC 60335-1 Clause 30.2 for household appliance safety. Protective treatment TH conforming to IEC 60068 means it is treated for tropical humid environments — condensation and corrosion resistance are built in. The mechanical robustness specs (3 Gn closed, 1.5 Gn open vibration; 10 Gn closed shock) confirm it holds its contacts under moderate industrial vibration.
