The Schneider Electric LC1E40B01F7 is an Easy TeSys Control contactor, 3-pole (3 NO), rated 40 A in AC-3 utilisation category at ≤440 V, with a 110 V AC coil. AC-3 rating means it handles the inrush of squirrel-cage motors during starting and switches them off under running conditions — the 40 A figure governs the motor full-load current it can manage, not the resistive heating current. The contactor also carries AC-1 (resistive) and AC-3e ratings, so it can serve heater banks or other non-inductive loads at a higher current than the AC-3 value, but the AC-3 number is the one that decides motor fit.
Mounts on DIN rail or plate. Dimensions are 84 mm high, 56 mm wide, 86 mm deep.
Operates at -5 to 55 °C ambient, stores at -60 to 80 °C, and runs without derating up to 3000 m altitude — fine for most indoor industrial sites and high-altitude plants. Mechanical robustness: closed contacts withstand 3 Gn vibration (5–300 Hz) and 10 Gn shock for 11 ms; open contacts handle 1.5 Gn vibration and 6 Gn shock. This is enough for machine-tool and conveyor applications with moderate vibration.
Certified to EN/IEC 60947-1, -4-1, -5-1, plus GB/T equivalents and EN/IEC 60335-1 Clause 30.2 (glow-wire) and EN/IEC 60335-2-40 Annex JJ.
