The Schneider Electric TeSys K LC2K16015F72 is a reversing contactor — a preassembled unit with the reversing power busbar already fitted. It is a 3-pole device rated for AC-3 and AC-4 duty. The rating is 16 A at ≤440 V in AC-3. The coil is 110 V AC.
The AC-4 rating covers reversing and plugging duty, where the contactor breaks at full load current, so that rating is typically lower; the evidence does not give a separate AC-4 current figure, but the dual utilization category confirms the contactor is built for the mechanical stress of frequent reversals. The 690 V AC rated operational voltage on the power circuit means it can also switch on a 690 V line if derated — but the 16 A AC-3 rating is only valid up to 440 V. Above that, the current must be reduced per the manufacturer's derating curve. The IP20 finger-safe terminals are standard for enclosed panel mounting; no washdown protection here.
The shock and vibration ratings are solid for a reversing contactor that sees frequent mechanical cycling: it holds closed through 10 Gn on Y and Z axes, and 15 Gn on X. The V1 flame retardance rating per UL 94 means the housing material self-extinguishes — relevant for panel certification.
The IP20 terminals accept standard ring or fork crimp lugs. The 1 NC auxiliary contact is built in — useful for a feedback signal to the PLC or to interlock the forward and reverse coils in the safety circuit. The coil is 110 V AC, so verify your control transformer voltage matches before wiring.
