The Schneider Electric TeSys K LC2K16107C72 is a reversing contactor — three poles, rated for AC-3 duty up to 440 V at 16 A, with a 36 V AC coil. It comes preassembled with the reversing power busbar, so you don't need to wire the mechanical interlock or busbar yourself; it's a drop-in reversing starter for a three-phase motor. The AC-3 rating means it's built for starting and stopping squirrel-cage motors — the 16 A at <=440 V covers a motor up to roughly 7.5 kW depending on the exact line voltage and duty cycle. The AC-4 category also listed means it can handle inching and plugging, where the contactor opens under full locked-rotor current.
IP20 finger-safe terminals (per VDE 0106) mean it's suited for enclosed panels where personnel access is controlled.
It's part of the TeSys K range, which is Schneider's compact contactor family for motor control up to about 20 A. The whole series shares the same DIN-rail footprint and accessory ecosystem (auxiliary contact blocks, surge suppressors, thermal overloads), so if you're standardizing on TeSys K, this reversing contactor fits the same bin.
The 36 V AC coil is a specific voltage — common in control transformers for older or safety-isolated circuits, but not the 24 V DC or 110 V AC you see on most modern PLC outputs. Make sure your control transformer or power supply delivers 36 V AC at the coil's inrush current (typically around 30 VA for this frame size). The coil is AC, so a DC supply won't pull it in. The reversing busbar is preassembled, which saves panel-building time but also locks the mechanical interlock orientation. If you need to reverse the rotation direction or change the pole arrangement, you're working with the factory busbar — not a field-reversible kit. That's a one-way assembly.
