The LC1K06016L7 is a Schneider TeSys K three-pole contactor rated for AC-3 duty at 6 A up to 440 V, with a 200...208 V AC coil and one normally closed auxiliary contact. It switches motor loads up to 1.5 kW at 220-230 V, 2.2 kW at 380-415 V, or 3 kW at 440-690 V — the higher voltage ranges let it handle the same motor current at a lower line draw. The 1.3 W heat dissipation stays low enough that it won't cook neighbouring components in a crowded panel.
For a BOM freeze or line-down replacement, the closest functional match in the TeSys K family shares the same 45 mm width and 58 mm height footprint, but verify the coil voltage and auxiliary configuration against your panel wiring.
