Integrator's note on the LC1E0901BD
The LC1E0901BD is a 3-pole contactor from Schneider Electric's Easy TeSys Control range, rated 9 A in AC-3 duty (motor switching) at ≤440 V, with a 24 V DC coil and one normally-closed auxiliary contact. AC-3 is the utilisation category for squirrel-cage motor starting — 9 A covers small motors up to roughly 4 kW at 400 V three-phase. Mounts on DIN rail or plate (screw fixing), with IP20 finger-safe terminals. The 45 mm width (3-module footprint) fits standard enclosure cutouts. Rated for operation up to 3000 m without derating, and ambient air from -20 to 70 °C at the coil — though the operating window narrows to -5 to 55 °C for the full thermal spec.
Certified to EN/IEC 60947-1, 60947-4-1, and 60947-5-1, plus the Chinese GB/T equivalents. Protective treatment TH conforms to IEC 60068-2-30 (damp heat cyclic). The mechanical robustness specs — 5 Gn shocks contactor open, 10 Gn closed, vibration 1.5–3 Gn — are standard for industrial panel mounting.
