- Description
The Schneider Electric LC1D18KUE is a 3-pole TeSys Deca contactor rated 18 A AC-3 (up to 440 V) for direct-on-line motor control, switching motors up to 7.5 kW at 400 V. It carries a 100-250 V AC/DC electronic coil, a mechanically-linked 1 NO + 1 NC auxiliary contact with mirror-contact certification, and screw-clamp terminals for DIN-rail or plate mounting.

Selection Notes
The 100-250 V AC/DC electronic coil accepts both AC and DC supply over its full voltage band, so the same reference covers 100-250 V control circuits without a separate AC or DC part number, and its low hold-in consumption reduces heat inside the enclosure versus a conventional coil. The mirror-contact-certified 1 NO + 1 NC auxiliary block confirms power-contact position for safety circuits without an external contact block.
