The Schneider Electric LC1E2510N5WB is a 3-pole contactor from the Easy TeSys Control range, rated 25 A in AC-3 utilisation category at 400 V — that's the motor-switching current, so it handles a 3-phase induction motor up to roughly 11 kW at 400 V without derating. The coil is 415 V AC wide-range, meaning it pulls in reliably across a band of supply voltages, not just a single nominal. It also carries an AC-1 resistive load rating for heater or lighting circuits.
The AC-3e suffix means it's also tested for energy-efficient motors with higher inrush, common in modern IE3/IE4 classes. For resistive loads (AC-1), the thermal current is higher — the datasheet curve governs the exact figure, but the contactor body is sized for the 25 A AC-3 frame. The 415 V AC coil is a wide-range type, so it operates across a voltage band (typically 0.85 to 1.1 x Uc, though the exact hold/dropout thresholds are in the datasheet). This matters if your control transformer is tapped at 400 V or 480 V — the wide-range coil avoids a separate coil changeout. The permissible ambient is -20 to 70 °C at coil rated voltage, with operation limited to -5 to 55 °C. Below that, no reduction in ratings.
Mounts on DIN rail (35 mm symmetrical rail) or directly to a plate via screws. IP20 means finger-safe terminals but no washdown protection — keep it inside a sealed cabinet or a clean indoor panel. The 3-pole configuration (3 NO main poles) suits a standard three-phase motor circuit. No built-in auxiliary contacts on this variant — add a side-mount auxiliary block if you need feedback to a PLC or status indication.
Also complies with EN/IEC 60335-1 Clause 30.2 for glow-wire and EN/IEC 60335-2-40 Annex JJ for heat-pump applications. Protective treatment TH per IEC 60068-2-30 means it withstands tropical humid conditions — relevant for export or coastal installations.
