The LC2K1610D72 is a TeSys K reversing contactor from Schneider Electric — a 3-pole unit rated for AC-3 duty at 16 A up to 440 V, with a 36 V AC coil and one normally open auxiliary contact. It comes preassembled with the reversing power busbar, so you don't need to build the interlock wiring yourself; that's one less step in the panel. The AC-3 rating (16 A at ≤440 V) means it's sized for starting and stopping squirrel-cage motors under load — the standard utilisation category for motor contactors. The 36 V AC coil is a control-voltage common in older or safety-isolated circuits; verify your transformer taps before wiring.
Flame retardance meets UL 94 V1 and NF F 16-101/102, so it's acceptable for rail and transit applications where fire-smoke-toxicity requirements apply. Operating altitude is 2000 m without derating; above that, you'll need to factor in air-density cooling loss.
Because it's a current TeSys K part, cross-referencing to a different frame or coil voltage is straightforward within the same family — but the reversing busbar is pre-assembled here, so swapping to a non-reversing variant would lose that integration.
