The LC1E1810N5WB is a 3-pole contactor from the Easy TeSys Control range, rated for AC-3 duty at 32 A at 400 V. That AC-3 utilisation category means it's built for switching squirrel-cage motors — making and breaking currents during start-up and running. The 415 V AC wide-range coil lets it pull in reliably across a broader voltage band than a fixed-coil part, which simplifies stocking for panels fed by different supply taps. The 80 mm depth fits standard 100 mm deep enclosures without crowding the gland plate.
The 45 mm width leaves room for a three-pole contactor plus an auxiliary block in a standard 8-module enclosure row. Operating altitude goes to 3000 m without derating, so it's fine for high-altitude plants. Vibration and shock ratings are specified for both open and closed states — 3 Gn closed, 10 Gn shock closed — which matters for installations near rotating machinery.
