Rated AC-3 ≤440 V 16 A, it handles reversing duty on three-phase induction motors up to roughly 7.5 kW at 400 V. The 24 V AC coil keeps control-circuit isolation simple in panels where the PLC or relay output already runs at that voltage. The 16 A AC-3 rating is the motor-switching current — the value that governs real-world fit for starting and stopping a squirrel-cage motor under load. AC-4 is also listed, covering plugging and inching duty where the contactor opens under stalled-rotor current. For reversing applications the AC-4 rating matters because the contactor may break current while the motor is still spinning in the opposite direction.
The TeSys K series is a well-established compact contactor family. If your panel design calls for a different coil voltage or a different auxiliary contact configuration, the family includes variants that share the same footprint and busbar system — but the LC2K1601B72 is the specific reversing assembly with one NC auxiliary contact and a 24 V AC coil. No pin-compatible direct substitute from another manufacturer exists; the reversing busbar and mechanical interlock are integrated at the factory.
The contactor carries IP20 protection (VDE 0106), V1 flame retardance (UL 94), and compliance with NF F 16-101 / 16-102 for rail-vehicle fire behavior. Protective treatment per IEC 60068 and DIN 50016 covers corrosion resistance. Shock and vibration ratings per IEC 60068-2-27 and IEC 60068-2-6 are documented — contactor closed withstands 10 Gn on Y and Z axes, 6 Gn on X when opened.
