The Schneider Electric TeSys K LC8K1201B7 is a 3-pole reversing contactor rated for AC-3 duty at 12 A up to 440 V, with a 24 V AC coil and one NC auxiliary contact. It arrives preassembled with the reversing power busbar, so the mechanical interlock and bus connections are already in place — one less assembly step in the panel. The AC-3 rating (12 A at ≤ 440 V) means it is sized for switching squirrel-cage motors under full load — starting, stopping, and reversing — without excessive contact wear. The 24 V AC coil keeps control voltage at a safe low level, typical for PLC-driven or relay-logic control circuits.
The IP20 finger-safe enclosure per VDE 0106 means it is suitable for enclosed panel installation where operators do not contact live parts during normal operation. For installations above 2000 m, consult the thermal derating curve in the full datasheet.
Because it is an active TeSys K catalog item, the documentation package (declaration of conformity, RoHS/REACH compliance, UL/CSA/CE marks) is available through the standard Schneider documentation portal. The V1 flame retardance and IP20 ratings are factory-tested and marked on the nameplate.
Mechanical robustness for industrial environments
The contactor is tested to IEC 60068-2-27 for shock and IEC 60068-2-6 for vibration. With the contactor closed, it withstands 10 Gn on the X axis and 15 Gn on Y and Z axes for 11 ms. Vibration resistance is 4 Gn from 5 to 300 Hz when closed. These ratings confirm it holds its state under the mechanical stress typical of conveyor drives, compressors, and pump skids. Protective treatment conforms to IEC 60068 and DIN 50016, which covers resistance to corrosive atmospheres — relevant for installations near chemical processing or coastal environments where salt mist and humidity accelerate contact degradation.
