The LC7K09105FE7 is a 3-pole TeSys K contactor from Schneider Electric, designed for motor control and general switching in industrial panels. Motor power capability spans the common three-phase voltages: 4 kW at 380–415 V and 480 V, 2.2 kW at 220–230 V, and 4 kW at 500–600 V and 660–690 V. That covers most standard 50/60 Hz supplies across European and North American panels without needing a voltage-specific variant.
Withstand and coordination
The power circuit can handle 90 A for 1 second, 85 A for 5 seconds, and 60 A for 30 seconds under short-time withstand (Icw). That gives the upstream breaker or fuse enough time to clear without welding the contacts — useful when coordinating selectivity downstream of a motor branch circuit. The signalling circuit (aux contact) withstands 110 A for 100 ms, which is typical for pilot-duty switching.
