The LC1K09106N7 is a 3-pole TeSys K contactor from Schneider Electric, rated 9 A in AC-3 duty at ≤440 V, with a 400…415 V AC 50/60 Hz coil. It carries motor power ratings up to 4 kW across common industrial voltages (380–690 V AC). The utilisation categories cover AC-1 resistive, AC-3 motor starting, and AC-4 plugging/inching duty, so it handles both standard and reversing applications in control panels.
The 400…415 V AC coil means it pulls in reliably on a standard European 400 V three-phase supply without a control transformer. Heat dissipation is 1.3 W, which is low enough that no special ventilation is needed in a typical DIN-rail enclosure. The 3 NO main poles and one normally open auxiliary contact are built in; no add-on aux block needed for basic signalling.
