The Schneider Electric LC1E40B01M7 is an Easy TeSys contactor — a 3-pole (3 NO) motor-switching device rated 40 A in AC-3 duty at up to 440 V, with a 220 V AC coil.
The AC-3 rating of 40 A at 440 V is the number that governs motor switching — it means the contactor can make and break a 3-phase induction motor load up to that current, covering most 18.5 kW motors at 400 V. AC-1 (resistive) and AC-3e (enhanced motor) categories are also listed, giving flexibility for heater banks or high-efficiency motor starts. The 220 V AC coil is common in European and Asian control circuits; verify your control voltage matches before panel integration, as coil burn-out is a common commissioning error. The IP2X degree of protection means it's finger-safe but not sealed; install inside an enclosure for washdown or dusty environments. Operating altitude goes to 3000 m without derating, useful for high-altitude installations. Mechanical robustness is specified: vibrations at 1.5 Gn (open) and 3 Gn (closed) over 5–300 Hz, and shocks at 6 Gn (open) and 10 Gn (closed) for 11 ms. These numbers matter for applications on conveyors, shuttle systems, or mobile equipment where the contactor sees continuous vibration.
Also complies with EN/IEC 60335-1 Clause 30.2 and EN/IEC 60335-2-40 Annex JJ for appliance safety. These standards make it acceptable for industrial panels and HVAC equipment in most markets.
