The LC2K1601D7 is a TeSys K reversing contactor from Schneider Electric — a 3-pole unit preassembled with a reversing power busbar, rated for AC-3 duty at ≤440 V and 16 A, with one NC auxiliary contact and a 42 V AC coil. It is designed for motor control applications where direction reversal is needed, such as conveyors, hoists, or pump drives.
The AC-3 rating of 16 A at ≤440 V tells you this contactor is sized for switching three-phase induction motors under full load — the typical duty cycle for starting and running a motor, not just resistive loads.
The contactor handles shock and vibration per IEC 60068-2-27 and IEC 60068-2-6 — closed contacts survive 10 Gn on Y and Z axes, 6 Gn on X, so it holds in on a vibrating conveyor line. Flame retardance meets UL 94 V1 and NF F 16-101/102, which matters for rail or transit applications.
The preassembled reversing busbar saves wiring time but locks the pole arrangement — no field reconfiguration of the power circuit.
