The LC1E3801M5WB is a Schneider Electric Easy TeSys Control contactor, now classified as obsolete. It is a 3-pole (3NO) device rated for AC-3 and AC-3e utilisation categories at 38 A up to 440 V, with a 220 V AC 50 Hz wide-range coil and one normally-closed auxiliary contact. This is a motor-control and resistive-load switching contactor built to EN/IEC 60947-4-1 and GB/T 14048.4 standards, with IP20 finger-safe protection for panel installation.
The AC-3e rating extends this with enhanced electrical endurance for high-cycle applications like conveyors or compressors. The 220 V AC 50 Hz coil is a wide-range type, meaning it holds in across a voltage band around the nominal, but the coil dropout threshold still follows the standard IEC 60947-4-1 undervoltage release curve. The single NC auxiliary contact (1NC) is wired as a feedback or interlock signal; if your circuit requires more auxiliary poles or a different configuration, an external auxiliary contact block must be added.
The LC1E3801M5WB carries declarations of conformity to EN/IEC 60947-1, EN/IEC 60947-4-1, EN/IEC 60947-5-1, and the equivalent GB/T 14048 series for the Chinese market. It also meets EN/IEC 60335-1 Clause 30.2 for glow-wire / fire resistance and EN/IEC 60335-2-40 Annex JJ for heat pump / air-conditioning applications. It is rated for operation up to 3000 m altitude without derating.
Mechanical & Environmental Limits
The contactor is rated for vibration resistance at 1.5 Gn (open) and 3 Gn (closed) across 5–300 Hz, and shock resistance at 6 Gn (open) and 10 Gn (closed) for 11 ms. These ratings confirm suitability for standard industrial panel environments with moderate mechanical stress.
