The Schneider Electric TeSys K LC2K16105M7 is a reversing contactor — three poles, preassembled with the reversing power busbar so you don't need to build the mechanical interlock and busbar stack yourself. It's rated for AC-3 duty at 16 A up to 440 V, with a 220…230 V AC 50/60 Hz coil.
The headline AC-3 rating of 16 A at ≤440 V tells you this contactor handles motor full-load current up to that level. The coil pulls 220…230 V AC — common across European and Asian control circuits — and the contactor also carries an AC-4 utilisation category for plugging and inching duty, where the motor is reversed or stopped by counter-torque before it's at rest. The operating altitude of 2000 m without derating covers most installations; above that, you'd need to account for reduced air dielectric and cooling.
Mechanical robustness and environment
Rated for 10 Gn shocks on the Y and Z axes (contactor closed) and 4 Gn vibration at 5…300 Hz (contactor closed) per IEC 60068-2-27 and IEC 60068-2-6. That's enough for most industrial machinery — conveyors, pumps, compressors — but if your application sees sustained high-frequency vibration near the contactor's resonance band, you may want to check the opened-contactor limits (2 Gn vibration).
