The LC2K16017U7 is a TeSys K reversing contactor from Schneider Electric — a compact 3-pole unit rated for AC-3 motor duty at 16 A up to 440 V, with a 230…240 V AC coil and one NC auxiliary contact. It arrives preassembled with the reversing power busbar, which saves panel wiring time on forward-reverse motor circuits for conveyors, pumps, and small hoists. The IP20 finger-safe enclosure (VDE 0106) means it can sit on a DIN rail inside a standard control panel without additional shrouding.
The AC-3 utilisation category rating of 16 A at ≤440 V governs motor switching: it handles the inrush and breaking of a squirrel-cage motor up to roughly 7.5 kW at 400 V. The 230…240 V AC coil pulls in reliably across that range, and the single NC auxiliary gives you a feedback or interlock signal for the reversing logic. The contactor is also rated for AC-4 duty (plugging / inching), so it can handle the higher electrical wear of frequent reversals — useful on indexing tables or shuttle conveyors. Storage range extends from -50…80 °C, so it holds up in unheated warehouses. Mechanical robustness is specified for shock and vibration: the contactor stays closed under 10 Gn on Y and Z axes (11 ms half-sine), and open contacts withstand 6 Gn on X. Vibration resistance is 4 Gn closed, 2 Gn open across 5…300 Hz — adequate for most machine-mounted panels.
