The TeSys K LC1K12106Q7 is a 3-pole contactor from Schneider Electric's compact TeSys K range, built for control applications. It carries a 380-400 V AC coil and is rated for AC-3 duty at 12 A up to 440 V, meaning it handles motor starting and stopping within that envelope — the AC-3 category covers squirrel-cage motors with switching during running, which is the standard for most conveyor, pump, and fan loads. The same contactor also covers AC-1 (resistive) and AC-4 (plugging/inching) utilisation categories, so it can serve both heater banks and reversing applications. Motor power ratings span from 3 kW at 220-230 V AC up to 5.5 kW at 380-415 V and 440 V, and 4 kW at 480 V through 660-690 V AC. That range covers common low-voltage three-phase supplies across Europe and North America. Heat dissipation is only 1.3 W, which keeps panel temperature rise negligible in a densely packed enclosure.
Integration notes
The 380-400 V AC coil is a standard industrial control voltage across much of Europe and Asia; confirm the control transformer taps before wiring.
