The Schneider Electric LC1E40B7 is a 3-pole contactor from the Easy TeSys Control range, rated for 40 A in AC-3 and AC-3e duty at up to 440 V, with a 24 V AC 50/60 Hz coil.
Dimensions are 75 mm wide, 127 mm high, 114 mm deep — check gland-plate clearance if you are panel-building with a shallow enclosure. The IP2X finger-safe cover is already built in per IEC 60529.
Environmental and mechanical limits
Operates from -5 °C to 55 °C ambient, stores from -60 °C to 80 °C. No derating needed up to 3000 m altitude — useful if this goes into a high-altitude installation. Vibration resistance is 1.5 Gn contacts open, 3 Gn closed; shock resistance 6 Gn open, 7 Gn closed. The TH protective treatment handles pollution degree 3 environments per IEC 60068-2-30, so it is suited for humid or mildly aggressive atmospheres.
Certified to EN/IEC 60947-1, 60947-4-1, 60947-5-1, plus GB/T equivalents for the Chinese market.
