The LC1K16016N7 is a three-pole contactor from the TeSys K series, designed for motor control and general switching in control panels. It carries a 16 A rated operational current in AC-3 utilisation category (switching squirrel-cage motors) and also covers AC-1 resistive loads. Motor power capability varies by supply voltage: 7.5 kW at 380…415 V AC, 5.5 kW at 440 V AC, 4 kW at 480 V AC and at 500…600 V AC, and 4 kW at 660…690 V AC. This makes it a compact fit for a 7.5 kW motor on a standard 400 V three-phase line, or a 5.5 kW motor on a 440 V line.
There is no official manufacturer successor listed for the LC1K16016N7, so a parametric substitute from the current TeSys range would need to be evaluated based on mounting footprint, coil voltage, and auxiliary contact configuration.
The AC-1 rating (resistive) is higher, but for motor duty, the AC-3 number is the one to match against the full-load current of the motor. Dimensions are compact: 45 mm wide, 58 mm high, 57 mm deep. The 1.3 W heat dissipation is low, so no special ventilation is needed in a typical enclosure. The contactor is rated for short-time withstand currents (Icw) up to 115 A for 1 second on the power circuit, and up to 110 A for 100 ms on the signalling circuit. This gives some fault-withstand margin for coordination with upstream protection.
