The Schneider Electric LC1E1810B6 is a 3-pole contactor from the Easy TeSys Control range, rated 18 A in AC-3 / AC-3e utilisation category at ≤440 V — meaning it switches standard three-phase squirrel-cage motors up to that current during starting and stopping, where the load current during acceleration is typically 5–7× the rated full-load current. The 24 V AC 60 Hz coil draws its control power from a dedicated transformer or control circuit; the 1 NO auxiliary contact provides a feedback or interlock signal without an add-on block. Rated operational voltage is listed for the power circuit; the control circuit is isolated.
The 18 A AC-3 rating, 24 V AC 60 Hz coil, 1 NO auxiliary, and DIN-rail footprint must be matched in a substitute.
Standards and compliance — what the approvals cover
It also complies with EN/IEC 60335-1 Clause 30.2 and EN/IEC 60335-2-40 Annex JJ for glow-wire and fire-resistance requirements — relevant if the contactor is used inside a household or commercial appliance. Protective treatment is TH (tropicalised, pollution degree 3) per IEC 60068-2-30, meaning it withstands high humidity and cyclic condensation — suitable for non-condensing environments in warm climates.
Environmental limits — where it can run
Permissible ambient air temperature around the device is -20 to 70 °C at the coil rated voltage (Uc), with storage from -60 to 80 °C, and operation from -5 to 55 °C. The narrower operating range (-5 to 55 °C) is the one that governs real panel conditions — the wider storage range simply means the part can survive shipping and warehouse extremes without damage. Mechanical robustness is specified at 1.5 Gn vibration (5–300 Hz) with contacts closed, and 10 Gn shock for 11 ms with contacts closed.
