Part identity and key ratings
The Schneider Electric LC1E40BD is a 3-pole (3NO) contactor from the Easy TeSys Control range, rated 40 A in AC-3 and AC-3e utilisation categories at ≤440 V, with a 24 V DC coil. The AC-3 rating means it is sized for starting and stopping squirrel-cage motors under load — the duty that governs contactor selection for most conveyor, pump, and fan applications. The AC-1 rating covers resistive loads, so the same contactor can switch heater banks or lighting circuits at a higher current, but the AC-3 figure is the one that decides fit for motor control.
Designed to EN/IEC 60947-1, 60947-4-1, and 60947-5-1, plus the Chinese GB/T equivalents — so it is accepted across European and Asian panel builds. IP20 finger-safe terminals suit enclosed panel mounting on a DIN rail or plate.
The LC1E40BD is marked obsolete by the manufacturer. No official successor order code is listed in the lifecycle record. The mechanical and electrical ratings (40 A AC-3, 24 V DC coil, 3P frame) define the form-fit-function envelope if a cross-reference is needed, but no direct pin-compatible replacement is confirmed from the manufacturer.
Mechanical and mounting details
The non-overlap time between NC and NO contacts is guaranteed at 1.5 ms on both energisation and de-energisation — relevant for interlocking circuits where contact overlap could cause a short. Mechanical robustness tested to 5 Gn shocks (contactor open) and 7 Gn (closed), with vibration resistance up to 3 Gn at 5–300 Hz when closed. Operating altitude is 3000 m without derating.
