The LC1K06015Q7 is a TeSys K contactor from Schneider Electric, configured as a 3-pole normally open device with one normally closed auxiliary contact. It is rated for AC-3 and AC-4 utilisation categories at 6 A up to 440 V, with a 380-400 V AC coil. This is a motor-control contactor sized for small induction motors in the fractional-to-low horsepower range, typically found in conveyor drives, pump starters, or fan controls within a control panel.
AC-3 covers starting and stopping of squirrel-cage motors where the inrush can be 6-8 times the rated current. AC-4 adds plugging and inching duty — reversing or jogging — which stresses the contacts harder. This contactor is built for that cycle, but the 6 A figure is the continuous motor full-load current, not the break current.
That is a standard European industrial control voltage range. Operating altitude is 2000 m without derating, which covers most installations below that elevation. No IP rating is listed in the spec — this is an open-device contactor intended for enclosure mounting where the panel provides the environmental seal.
