The Schneider Electric LC2K16105M72 is a TeSys K reversing contactor — a 3-pole unit rated for AC-3 duty at 16 A (≤440 V) with a 220…230 V AC coil, preassembled with the reversing power busbar so you don't have to build the interlock wiring yourself. It's designed for motor control in control panels, switching direction on conveyors, pumps, or fans where you need forward/reverse without a separate mechanical interlock assembly.
If you're looking for a drop-in replacement, the TeSys K series has been superseded by the TeSys Deca and TeSys Giga lines, but those are different form factors and mounting patterns — not pin-compatible. You'll need to re-evaluate panel layout and wiring if you move to a current-production series.
The 3 NO power poles handle the motor lines; the single NO auxiliary contact is built in for status feedback or seal-in logic. Wire it as a standard reversing pair: line to common, load to motor, with the coil interlocked through the opposite contactor's NC auxiliary (which you'll need to add externally, since this unit only carries one NO).
