The LC1K06015R7 is a TeSys K contactor from Schneider Electric, a 3-pole unit rated for AC-3 and AC-4 utilisation categories. Its rated operational current is 6 A at <= 440 V for motor switching, with a 440 V AC coil. The contactor carries motor power ratings from 1.5 kW at 220-230 V AC up to 3 kW at 480 V and 660-690 V AC, covering common three-phase supply voltages across 50/60 Hz systems.
Short-time withstand and duty cycle
The power circuit handles short-time withstand currents (Icw) of 90 A for 1 second, 80 A for 10 seconds, and 20 A for durations of 15 minutes or longer at 50 °C. These ratings define the contactor's ability to ride through fault conditions without welding — useful for coordination studies in motor branch circuits. The signalling circuit (auxiliary contacts) withstands 110 A for 100 ms.
