The Schneider LC1E09008N5WB is a 4-pole Easy TeSys contactor with a 415 V AC 50 Hz coil, rated for 20 A in AC-1 duty at ≤440 V. That AC-1 rating means it's sized for resistive loads — heaters, lighting banks, or other non-inductive circuits — not motor starting. The 4-pole configuration gives you 2 NO and 2 NC main poles, which covers most switching and isolation needs in a resistive load panel without needing an extra contactor for the neutral.
The rated breaking capacity of 72 A at 440 V and making capacity of 90 A at 440 V tell you it can handle occasional fault clearing without welding contacts — important for coordination with the upstream 12 A gG fuse (coordination type 1) specified for the power circuit. The control circuit is a wide-range AC coil at 50 Hz, 415 V nominal. Drop-out voltage is 0.3 to 0.6 Uc, operational range 0.7 to 1.25 Uc. That's a standard range for industrial AC coils — it'll hold in through brownouts down to about 290 V and pick up reliably at 290 V. Inrush power is 95 VA at cos φ 0.75, with heat dissipation of 2 to 3 W once sealed. Keep that in mind for transformer sizing if you're running multiple contactors off one control transformer.
Mounts on DIN rail or plate. The 45 mm width (3 modules wide) fits standard 45 mm DIN-rail spacing. Screw clamp terminals accept 1 to 4 mm² flexible with cable end or solid on the power circuit, and 1 to 4 mm² on control. Tightening torque is 1.2 N.m for both — a standard screwdriver setting, no special tooling.
That covers the contactor as a whole, the motor-starter combination (even though this is AC-1 rated), and the control circuit. IP20 finger-safe protection on the terminals. Protective treatment TH per IEC 60068-2-30 means it's treated for tropical humidity — not a washdown rating, but okay for most indoor industrial environments.
