The Schneider Electric LC1E18004P7IN is a 4-pole (4NO) contactor from the Easy TeSys Control range, rated for resistive loads in AC-1 utilisation category at 40 A up to 415 V, with a 230 V coil.
The contactor complies with EN/IEC 60947-1, EN/IEC 60947-4-1, and EN/IEC 60947-5-1, plus the Chinese GB/T equivalents, and carries 850 °C glow-wire fire resistance per IEC 60695-2-1. The protective treatment meets pollution degree 3 (TH) per IEC 60068, so it holds up in industrial environments with moderate condensation and conductive dust.
At 45 mm wide, 74 mm tall, and 80 mm deep, the LC1E18004P7IN fits a standard DIN-rail footprint or plate-mount layout. The operating ambient range is -5 to 55 °C, with storage from -60 to 80 °C, and it is rated for altitudes up to 3000 m without derating.
