The LC1E3810Q7 is a 3-pole contactor from the Easy TeSys Control range, rated 38 A in AC-3 duty at ≤440 V — that is the motor-switching current, not the resistive load rating. It carries a 380 V AC coil (50/60 Hz) and one normally-open auxiliary contact. The part is now listed as obsolete by the manufacturer, so any procurement decision should account for last-time-buy or replacement planning.
AC-3 rating of 38 A at ≤440 V covers motor switching for three-phase induction motors. The AC-3e category extends the same rating for energy-efficient motors with higher inrush. Mechanical robustness: the contactor withstands 1.5 Gn vibration when open, 3 Gn when closed, and 10 Gn shock for 11 ms when closed. That is typical for general industrial panel mounting — not rated for high-shock mobile equipment, but fine for fixed conveyors, pumps, and compressors. Operation limited to -5 to 55 °C — that is the functional window for coil pick-up and hold.
Designed to EN/IEC 60947-1, -4-1 (contactor), and -5-1 (control circuit), plus Chinese GB/T equivalents. Protective treatment TH conforms to IEC 60068-2-30 for damp heat (pollution degree 3). IP2X finger protection on the front face.
Sourcing Reality for an Obsolete Part
The LC1E3810Q7 is obsolete per the manufacturer. No successor order code is listed.
