The Schneider Electric LC2K16017J7 is a TeSys K reversing contactor — a 3-pole, 3 NO power pole unit with a 12 V AC coil and one NC auxiliary contact. It is rated for AC-3 duty at 16 A up to 440 V, which means it handles reversing motor loads (forward-reverse) in control panels. The part ships preassembled with the reversing power busbar, saving panel-build time.
The AC-3 rating of 16 A at <=440 V is the motor-switching current — this contactor can start and stop a reversing 3-phase motor up to that load. The 12 V AC coil means the control circuit must supply 12 VAC; verify your transformer or control voltage matches. IP20 finger-safe protection (VDE 0106) means it is suitable for enclosed panels where accidental contact is prevented by the enclosure door.
Integration notes
Mounts on a DIN rail. Dimensions: 90 mm wide, 58 mm high, 57 mm deep — fits standard panel layouts. The preassembled reversing busbar eliminates external wiring between the two contactor halves for forward and reverse. Operating temperature range is -25 to 50 °C; storage from -50 to 80 °C.
