The LC1K09013D7 is a 3-pole TeSys K contactor from Schneider Electric, rated for 9 A in AC-3 utilisation category at voltages up to 440 V. That AC-3 rating governs motor switching — it's the duty cycle that matters for starting and stopping squirrel-cage induction motors under load. The coil is 42 V AC, with one normally closed auxiliary contact built in.
Motor power capacity across voltages
This contactor handles 4 kW motor loads at 480 V, 500–600 V, and 660–690 V AC 50/60 Hz. Drop to 220–230 V and the rating is 2.2 kW. That voltage flexibility means the same part works across 230 V, 400 V, and 690 V line supplies — useful when panel designs span multiple regions or voltage classes.
Status is active per Schneider's lifecycle record — no phase-out or NRND flag. That means it's still a standard catalog line, not a last-time-buy scavenger hunt.
Heat dissipation is 1.3 W, so no special ventilation required in a standard IP2X enclosure. Flame retardance meets UL 94 V1 and NF F 16-101/102 Requirement 2, which covers rail and transit applications.
Short-time withstand and utilisation range
Rated short-time withstand current (Icw) for the power circuit is 90 A for 1 second, 80 A for 10 seconds, and 20 A for 15 minutes or longer. That tells you the contactor can ride through fault currents long enough for an upstream breaker to clear — useful for coordination studies. Utilisation categories cover AC-1 (resistive), AC-3 (motor start/run), and AC-4 (plugging/inching), so it's not limited to motor duty alone.
