The Schneider Electric LC1E40F6 is a 3-pole contactor from the Easy TeSys Control range, rated for AC-3 and AC-3e duty at 40 A up to 440 V, with a 110 V AC 60 Hz coil. The AC-1 rating covers resistive heating loads where the switching arc is less severe. The coil pulls in at 110 V AC, 60 Hz; verify your control transformer matches that frequency.
Dimensions are 75 mm wide, 127 mm tall, 114 mm deep — fits standard 35 mm DIN-rail enclosures with room for side-by-side auxiliary blocks.
Switching timing and mechanical robustness
Mechanically rated for 1.5 Gn vibration (contacts open) and 3 Gn (closed), plus shock tolerance of 6 Gn open and 7 Gn closed. That covers most conveyor, pump, and fan applications without additional dampening.
Also carries GB/T equivalents for the Chinese market. Fire resistance tested at 850 °C per IEC 60695-2-1, and the contactor meets glow-wire requirements of EN/IEC 60335-1 Clause 30.2 and EN/IEC 60335-2-40 Annex JJ — important for appliance and HVAC OEMs who need the contactor to pass the end-product glow-wire test.
