Schneider Electric TeSys K 3P mini contactor, 6 A AC-3 (2.2 kW at 400 V), 1NC aux, 380-400 V AC 50/60 Hz coil.
The Schneider Electric LC1K0601Q7 is a 3-pole TeSys K mini contactor rated 6 A AC-3 at up to 440 V (2.2 kW at 400 V), with a 1NC built-in auxiliary contact. It runs on a 380-400 V AC 50/60 Hz coil, connects via screw clamp terminals, and fits a 45 mm DIN-rail or plate-mount footprint rated to 3600 cyc/h.
The 6 A AC-3 rating sizes this contactor for a 2.2 kW motor at 400 V; step up to a higher-current TeSys K frame, or to TeSys Deca once past 16 A, for larger motors. The 1NC auxiliary contact is fixed at the factory and cannot be field-changed, so confirm the control-circuit logic needs 1NC before ordering rather than after.
