The Schneider Electric LC1E1210F5 is a 3-pole contactor from the Easy TeSys Control range, rated for AC-3 and AC-3e duty at 12 A up to 440 V, with a 110 V AC 50 Hz coil and one normally open auxiliary contact.
The 12 A AC-3 rating at ≤440 V is the number that decides whether this contactor handles your motor load — AC-3 covers starting and plugging of squirrel-cage motors, where inrush can be 6-8× the full-load current. The AC-3e variant extends that to energy-efficient motors with slightly different switching characteristics. The 110 V AC 50 Hz coil means it pulls in cleanly on a standard control transformer secondary; the 1.5 ms non-overlap time between NC and NO contacts on both energisation and de-energisation ensures the break-before-make sequence that prevents momentary short-circuits in reversing or star-delta circuits.
IP2X protection means it's finger-safe when installed in an enclosure, but it's not rated for washdown environments. It operates without derating up to 3000 m altitude, so it's fine for high-altitude plants or mine sites.
This contactor carries approvals to EN/IEC 60947-1, 60947-4-1, and 60947-5-1 — the core standards for low-voltage switchgear and controlgear. It also meets GB/T 14048 series for the Chinese market and EN/IEC 60335-1 Clause 30.2 plus 60335-2-40 Annex JJ for appliance applications. Mechanical robustness is specified for vibration (1.5 Gn open, 3 Gn closed) and shock (7 Gn open, 10 Gn closed) — figures that tell you it survives shipping and normal industrial vibration without welding contacts shut.
