The Schneider Electric LC1E32004V7IN is a 4-pole contactor from the Easy TeSys Control range, rated for AC-1 utilisation category at 55 A on power circuits up to 415 V. AC-1 covers resistive loads — heaters, lighting banks, non-inductive elements — where the switching current and load current are essentially the same. The 4 NO (normally open) pole configuration gives you four independently switched power paths in a single 56 mm wide package that mounts on DIN rail or a plate.
The headline 55 A at ≤415 V in AC-1 is the thermal current rating for resistive loads — this contactor can carry and break that current continuously under those conditions. The 4-pole arrangement means each NO pole shares the load; for a balanced three-phase resistive heater plus neutral, you'd use three poles for the phases and one for the neutral, staying within the 55 A per-pole limit.
At 56 mm wide, 64 mm tall, and 93 mm deep, this contactor fits standard DIN-rail enclosures or can be plate-mounted. The IP2X finger protection means the live terminals are shielded against accidental contact — enough for a general-purpose control cabinet but not for washdown areas. Operating ambient is -5 to 55 °C, with storage from -60 to 80 °C; the TH protective treatment (pollution degree 3 per IEC 60068) means it handles the dusty, humid conditions common in industrial panels without conformal coating.
