The Schneider Electric LC1E1801M6 is a 3-pole contactor from the Easy TeSys Control range, rated for 18 A in AC-3 utilisation category at up to 440 V. That AC-3 rating means it is designed for starting and stopping squirrel-cage motors — the most common motor-control duty — switching the load under full current. The 220 V AC coil is a standard control voltage for many industrial panels, so this part slots directly into existing 230 V control circuits without a transformer. It also carries an AC-1 rating for resistive loads, giving flexibility for heating or lighting banks, and an AC-3e rating for energy-efficient motors. The contactor is certified to EN/IEC 60947-4-1 (the main standard for contactors and motor-starters) and GB/T equivalents, plus EN/IEC 60335-1 for appliance safety — so it is accepted in both European and Chinese regulatory jurisdictions.
Operating altitude is 3000 m without derating, which covers most installations outside high-mountain sites. The contactor includes a guaranteed non-overlap time of 1.5 ms between NC and NO contacts on both energisation and de-energisation — a detail that matters for interlocking circuits where simultaneous closure could cause a short across the motor windings.
The TH protective treatment (pollution degree 3 per IEC 60068-2-30) means it withstands humid, tropical environments — a common requirement for HVAC or outdoor-adjacent panels. Fire resistance is tested to 850 °C per IEC 60695-2-1, which satisfies the glow-wire test for unattended appliances.
