The LC1E38004M7IN is a 4-pole (4 NO) Easy TeSys contactor from Schneider Electric, rated for AC-1 resistive loads at 20 A up to 415 V, with a 220 V AC coil. It's the straightforward choice for switching resistive loads like heaters or lighting banks in a control panel — no derating gymnastics for inductive kickback. That AC-1 rating means it's sized for resistive duty where inrush is minimal. If you're switching motor loads (AC-3), this isn't the contactor you want — the inductive break current would be lower. Stick to the spec: resistive loads only, up to 20 A continuous.
No special cutouts needed. IP2X finger protection on the contactor body means it's safe for open-panel mounting where incidental contact is possible, but it's not sealed against washdown. Keep it inside the enclosure.
Operates from -5 °C to 55 °C ambient, stores from -60 °C to 80 °C. Good for a heated plant floor or a cold warehouse — just don't try to switch it below -5 °C. Rated for altitudes up to 3000 m — no derating needed for most installations outside high-mountain sites.
