The Schneider Electric LC2K0601P72 is a TeSys K reversing contactor — a 3-pole unit rated 6 A in AC-3 (motor) duty at 440 V, with a 230 V AC coil and an integral suppression device built in. It ships preassembled with the reversing power busbar, so you mount it as one piece rather than wiring two contactors and a mechanical interlock separately. The utilisation categories cover AC-3 (squirrel-cage motor starting), AC-3e (high-efficiency motor start), and AC-4 (plugging/inching). The 6 A AC-3 rating means it handles motor inrush without welding the main poles. The 1 NC auxiliary is wired into the reversing interlock circuit out of the box.
For a 400 V three-phase motor, 6 A AC-3 corresponds roughly to a 2.2–3 kW load, depending on efficiency class. The flame retardance meets V1 per UL 94 and NF F 16-101/102, which is the rail-transport fire-smoke standard. Operating ambient is -25 to 50 °C, storage -50 to 80 °C. Shock and vibration ratings are given for both closed and open contactor states — the closed contactor holds through 10–15 Gn shocks depending on axis, which matters for mobile or rail-mounted gear.
The 3 NO main poles and 1 NC auxiliary are the contact complement; the NC is already committed to the reversing logic. The 230 V AC coil draws its rated inrush and hold current from the control transformer. The integral suppression device (RC snubber) is already in place across the coil — no external diode or varistor needed, which saves a wiring step and a DIN-rail slot.
No official successor or alternative order code is listed; the LC2K0601P72 is the active variant for this coil voltage and auxiliary configuration. If you are validating a new design, the TeSys K series is current and supported.
