The LC2K16105J72 is a TeSys K reversing contactor from Schneider Electric — a 3-pole unit rated 16 A in AC-3 duty at 440 V, with a 12 V AC coil. It comes preassembled with the reversing power busbar, so it saves panel wiring time on motor-reversing circuits (conveyor drives, pump direction change, actuator open/close).
AC-3 duty at 16 A covers small three-phase motor loads — think 5.5 kW at 400 V (roughly 12 A FLC) so there is headroom. The 12 V AC coil is uncommon in industrial panels (most are 24 VDC or 230 VAC); verify your control transformer output before specifying. The preassembled reversing busbar means the mechanical interlock and power wiring between the two contactor halves is factory-fitted — no risk of wiring a phase reversal wrong during panel build. Operating altitude rated to 2000 m without derating; beyond that, expect a current reduction per IEC 60947. Storage range -50 to 80 °C, operation -25 to 50 °C.
