The LC2K16017FC72 is a TeSys K reversing contactor from Schneider Electric — a 3-pole unit rated 16 A in AC-3 duty at 440 V, with a 127 V AC coil and one NC auxiliary contact. The AC-3 rating means it is sized for starting and stopping squirrel-cage induction motors under load — the standard duty for motor starters in conveyor, pump, and fan applications.
The 16 A AC-3 rating at 440 V governs motor switching capacity — it will handle a motor drawing up to roughly 7.5 kW at 400 V three-phase. The 127 V AC coil means the control circuit must supply that voltage; verify your control transformer taps before wiring. The operating altitude of 2000 m without derating covers most industrial sites; above that, dielectric and thermal margins shrink.
The preassembled reversing busbar saves panel space and wiring time compared to a discrete two-contactor reversing starter. Flame retardance meets UL 94 V1 and NF F 16-101/102, which matters for rail and transit applications where fire-smoke-toxicity requirements apply.
