The LC1E0910M5WB: The AC-3 rating (9 A at 400 V) is the one that governs motor switching — it tells you this contactor can break the locked-rotor current of a small induction motor up to about 4 kW at 400 V three-phase. The AC-1 rating covers resistive loads like heaters at a higher current, but for motor duty, AC-3 is the number to match to your load. The TH protective treatment (IEC 60068) adds a conformal coating that resists humidity and mild corrosive atmospheres, so it's a step above a bare industrial contactor for coastal or high-condensation environments.
The 80 mm depth leaves enough clearance for a typical 45 mm enclosure depth with wiring gutters. The 3 NO power poles handle the motor circuit; the contactor itself has no built-in auxiliary contacts (the '09' in the code means 3 main poles, zero auxiliaries), so if you need feedback to a PLC or a holding circuit, you'll add a side-mount auxiliary block from the Easy TeSys range.
Certified to EN/IEC 60947-4-1 (the contactor standard for motor starters) and EN/IEC 60947-5-1 (control circuit devices), plus the GB/T equivalents for the Chinese market. The active lifecycle status means the documentation, replacement parts, and compliance declarations are current — no PCN hunting needed for a new design-in.
