The Schneider Electric LC1E0901F7 is a three-pole (3NO) contactor from the Easy TeSys Control range, rated for AC-3 and AC-3e duty at ≤440 V, 9 A — that's the motor-switching rating, so it handles a 4 kW (approx. 5.5 HP) induction motor on a 400 V line. The 110 V AC coil at 50/60 Hz pulls in reliably across the -5 to +55 °C operating ambient range. One normally-closed auxiliary contact is built in for feedback or interlock wiring.
The IP2X finger-safe front keeps accidental contact out during commissioning. TH protective treatment per IEC 60068-2-30 means it survives humidity cycling (pollution degree 3) — a solid fit for a mill electrical room or a washdown-adjacent cabinet.
Rated for 3000 m operating altitude without derating — no need to oversize for high-altitude sites. Vibration tolerance: 1.5 Gn open, 3 Gn closed across 5–300 Hz. Shock survival: 7 Gn open, 10 Gn closed (11 ms half-sine).
