The Schneider Electric LC2K09103D72 is a TeSys K reversing contactor — a 3-pole, 3 NO power pole unit rated for AC-3 motor switching at 9 A up to 440 V, with a 36 V AC coil. It ships preassembled with the reversing power busbar, so the mechanical interlock and bus connections are factory-fitted, saving panel-build time on reversing starter assemblies.
The AC-3 rating of 9 A at ≤440 V governs motor switching — that is the current the contactor can make and break across an induction motor load under full-load running conditions. The 36 V AC coil means it is designed for control circuits at that voltage; verify your control transformer or PLC output matches before wiring. Mechanical robustness is specified per IEC 60068-2-27 and IEC 60068-2-6: the contactor withstands 10 Gn shock on X/Y/Z axes when closed, and 4 Gn vibration across 5–300 Hz. That is sufficient for most industrial panel environments, including conveyor and pump stations with moderate vibration.
Deployment context — panel integration
The preassembled busbar reduces wiring time for the reversing pair — just land the line and load connections. The 57 mm depth, 90 mm width, and 58 mm height fit a compact footprint; plan for adequate side clearance for heat dissipation and auxiliary contact access.
