The Schneider Electric LC1K0910Q7TQ is a TeSys K series 3-pole contactor rated for motor control in AC-3 and AC-3e utilisation categories at 9 A up to 690 V. The 380 VAC coil draws 30 VA inrush and 4.5 VA hold-in at 20 °C. It switches NO contacts in 10…20 ms and NC contacts in 15…25 ms on de-energisation.
Screw-clamp terminals accept 1.5…4 mm² solid or 0.34…2.5 mm² flexible with ferrule, one or two cables per clamp. The contactor has no built-in coil suppression module.
The 9 A AC-3 rating governs motor switching up to that current — the contactor is sized for a 3…4 kW motor at 400 V. Electrical durability is 1.3 million cycles at 9 A AC-3, and mechanical durability is 10 million cycles. The minimum switching capability is 5 mA at 17 V for the control circuit, so it can handle low-level PLC signals. Operating altitude is 2000 m without derating. Safety reliability is quantified: B10d of 1,369,863 cycles under nominal load per EN/ISO 13849-1.
Certified to EN/IEC 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, and JIS C8201-4-1. Flame retardance meets V1 per UL 94 and Class C2 per NF F 16-101/102. Storage temperature range is -50…80 °C.
