The Schneider Electric LC1E40B10U5 is a 3-pole (3 NO) contactor from the Easy TeSys Control range, rated for AC-3 duty at 40 A up to 440 V with a 240 V AC coil. The AC-3 rating means it can switch induction motor loads — making and breaking stalled-rotor currents — up to 40 A. The AC-1 rating covers resistive loads, and the AC-3e category extends the motor-switching capability for energy-efficient motors with higher inrush.
Mounts on a plate or DIN rail, fitting into a standard 56 mm wide footprint (84 mm height, 86 mm depth). The IP2X finger-safe enclosure suits panel-mount applications where accidental contact with live parts is prevented by the enclosure itself.
Also complies with GB/T 14048.1, GB/T 14048.4, and GB/T 14048.5. Permissible ambient air temperature ranges from -20 to 70 °C at the coil voltage, with storage from -60 to 80 °C and operation from -5 to 55 °C. Mechanical robustness includes vibration resistance of 1.5 Gn (contacts open) and 3 Gn (contacts closed) over 5–300 Hz, plus shock resistance of 10 Gn for 11 ms (closed) and 6 Gn for 11 ms (open).
