The Schneider Electric LC1E1210E5 is a 3-pole contactor from the Easy TeSys Control range, rated for AC-3 and AC-3e duty up to 440 V at 12 A, with a 48 V AC 50 Hz coil and one normally open auxiliary contact. It is designed for motor control and resistive load switching, with a mechanical life backed by vibration and shock ratings — 1.5 Gn open, 3 Gn closed for vibrations, and 7 Gn open, 10 Gn closed for shocks.
The AC-3 rating of 12 A at ≤440 V is the motor-switching current — this contactor can handle a 3-phase induction motor up to roughly 5.5 kW at 400 V, depending on the exact load and duty cycle. The AC-3e rating extends the same current for enhanced motor switching per IEC 60947-4-1. The 48 V AC coil draws from a control transformer; at 50 Hz the hold-in is reliable down to about 85% of rated voltage. The 1.5 ms non-overlap time between NC and NO contacts ensures no momentary short across the power poles during transition.
The IP2X finger-safe front cover is standard for panel installation.
Certified to EN/IEC 60947-1, 60947-4-1, 60947-5-1, plus GB/T equivalents for the Chinese market. Operating altitude up to 3000 m without derating; ambient range -20 to 70 °C at the coil, -5 to 55 °C for operation.
