The Schneider Electric LC1E3810M5WB is a three-pole (3 NO) contactor from the Easy TeSys Control range, rated for AC-3 duty at 50 A on 400 V and fitted with a 220 V AC wide-range coil. It is designed for motor switching and resistive load control in industrial control panels. The AC-3 utilisation category means it is rated for starting and stopping squirrel-cage motors — the 50 A figure at 400 V governs the motor full-load current it can handle, not the inrush. The AC-1 rating covers resistive loads such as heaters. AC-3e extends the motor rating to energy-efficient IE3/IE4 motors with higher starting currents.
Standards and compliance — what they certify
It also meets GB/T 14048.1/4/5 for the Chinese market and EN/IEC 60335-1 Clause 30.2 plus EN/IEC 60335-2-40 Annex JJ for appliance applications.
The 56 mm width and 86 mm depth fit a standard 8-module DIN-rail footprint; the 84 mm height leaves clearance under a 100 mm enclosure lid. IP20 finger-safe terminals allow panel wiring without additional shrouding. The TH protective treatment per IEC 60068 adds humidity resistance for tropical environments.
Mechanical robustness and environmental protection
The contactor withstands 1.5 Gn vibration when open and 3 Gn when closed (5–300 Hz). Shock resistance is 6 Gn open and 10 Gn closed (11 ms half-sine). These ratings confirm it holds its state under typical industrial vibration from adjacent contactors or motor starters.
