The LC1K09106L7 is a TeSys K 3-pole contactor rated 9 A in AC-3 and AC-3e utilisation categories at ≤440 V, with a 200…208 V AC coil. Rated operational voltage covers power circuit use up to 440 V; the signalling circuit handles frequencies up to 400 Hz. Minimum switching capability is 5 mA at 17 V for signalling, so it can reliably switch PLC-level signals without contact wetting issues.
The AC-3 rating of 9 A is the motor-switching current — that's the figure that governs real-world fit for standard squirrel-cage motors. Electrical durability at that rating is 1.3 million cycles; at AC-1 resistive load (20 A) it drops to 160,000 cycles, and at AC-4 (54 A inrush) to 20,000 cycles. Mechanical durability is 10 million cycles, so the contactor will outlast the machine's service life in most panel applications. Coil hold-in power is 4.5 VA at 20 °C; inrush is 30 VA. The coil has no built-in suppressor module, so you'll need to add an RC snubber or free-wheeling diode across the coil if driving it from a PLC output or solid-state relay. Operational voltage limits: coil picks up at 0.8 × Uc and drops out at 0.2 × Uc (below 50 °C). That gives a wide hold-in range — useful if your control transformer sags under load. Operating time is 10…20 ms for both closing and opening, consistent with standard IEC contactor response.
Terminals accept ring lugs with a 7 mm outer diameter. The 3 NO power poles and 1 NO auxiliary contact are fixed; no add-on contact blocks are needed for basic motor starter wiring.
