The Schneider Electric LC1E1801B5 is a 3-pole contactor from the Easy TeSys Control range, rated 18 A in AC-3 duty at ≤440 V, meaning it switches three-phase motor loads up to that current. The 24 V AC 50 Hz coil pulls in the main 3NO power poles, and the built-in 1NC auxiliary contact provides a feedback or interlock signal without needing a separate add-on block.
The 74 mm height and 80 mm depth fit standard 200 mm deep enclosures; leave clearance above for coil wiring and below for power terminations.
Rated for AC-3 (motor starting) and AC-1 (resistive load) utilisation categories. The 18 A AC-3 figure governs motor switching; for resistive loads the contactor can handle higher current per the AC-1 curve. The 1.5 ms non-overlap time between NC and NO contacts ensures the auxiliary breaks before the power poles make, preventing a momentary short across the coil circuit. Ambient temperature range is -20 to 70 °C at the coil, with storage down to -60 °C and operation at -5 to 55 °C. IP2X finger protection on the contactor body means it's safe for open-panel mounting where operators might reach in, but not for washdown environments — no IP65/IP67 rating here.
Also meets EN/IEC 60335-1 Clause 30.2 and -2-40 Annex JJ for appliance applications.
