The Schneider Electric LC1K1601P7TQ is a TeSys K three-pole contactor rated for 16 A in AC-3 duty (switching motor loads) up to 440 V, and also listed for AC-1 resistive loads. The 1 NC auxiliary contact is built in. The coil pulls in on 230 V AC. Motor power handling spans 4 kW at 220–230 V, 5.5 kW at 440 V, 7.5 kW at 380–415 V, and 4 kW at 480 V through 690 V, all at 50/60 Hz.
The 16 A AC-3 rating at ≤440 V is the headline motor-switching current — it governs the maximum motor full-load current this contactor can break under inductive load. The AC-1 rating covers resistive loads at a higher current, but for motor control, the AC-3 figure is the one that decides fit. Short-time withstand (Icw) is 115 A for 1 second on the power circuit, dropping to 55 A for 1 minute — this tells you the contactor can survive brief fault currents long enough for an upstream protective device to clear. Heat dissipation is 1.3 W, which matters for thermal management inside a crowded control panel. The housing carries a V1 flame-retardance rating per UL 94.
The 230 V AC coil means you need a control transformer or a separate AC supply for the coil circuit.
