The LC1E120M7 is a 3-pole contactor from the Easy TeSys Control range, rated 120 A in AC-3 duty and 96 A in AC-3e at ≤440 V. The 220 V AC coil at 50/60 Hz is fixed; if your control voltage is different, this isn't the variant you want. It also carries an AC-1 rating for resistive loads, meaning it can switch heaters or lighting banks where the current doesn't spike on make.
Mounts on DIN rail or plate, which gives you flexibility in panel layout — snap it on a rail for quick replacement or bolt it to a backplate in high-vibration environments. IP2X means finger-safe from the front but not sealed; keep it inside an enclosure.
Operating altitude goes to 3000 m without derating — useful for high-altitude installations where air density drops and contactors typically need to be de-rated. Ambient temperature range is -20 to 70 °C at the coil, with operation limited to -5 to 55 °C; storage from -60 to 80 °C.
