The Schneider Electric LC1E50U5 is a 3-pole (3NO) contactor from the Easy TeSys Control range, rated 50 A in AC-3 and AC-3e utilisation categories at ≤440 V, with a 240 V AC 50 Hz coil. It handles motor switching and resistive loads per EN/IEC 60947-4-1 and GB/T 14048.4. The AC-3 rating of 50 A means it can switch squirrel-cage motors up to that current during starting and running — the duty that generates the most contact wear. AC-3e extends that to high-efficiency motor profiles.
Mounts on either a DIN rail or a plate — the mounting support is listed as both. That matters for interlocking circuits where you need to ensure one set opens before the other closes — no overlap means no momentary short across the load.
Rated for operation at -5 °C to 55 °C ambient, with storage from -60 °C to 80 °C. Mechanical robustness: vibrations at 1.5 Gn (open) and 3 Gn (closed) over 5–300 Hz, shocks at 6 Gn (open) and 7 Gn (closed). IP2X finger protection on the contactor body.
