The Schneider Electric LC1K1210P7TQ is a TeSys K series 3-pole contactor rated for 12 A in AC-3 and AC-3e utilisation categories at 440 V, with a 230 V AC coil. The screw-clamp terminals accept solid or flexible cable from 0.34 to 4 mm², making it a straightforward fit for control panels with plate or DIN-rail mounting.
The 12 A AC-3 rating at 440 V is the headline motor-switching figure — it tells you the contactor can make and break a 3-phase induction motor drawing 12 A under full-load running conditions. The AC-3e variant adds a bit of margin for lightly inductive loads. For resistive heating or lighting, the AC-1 rating applies (20 A at 440 V), and for severe duty like plugging or inching, AC-4 is rated at 72 A but with much lower electrical endurance (0.02 Mcycles). The coil holds in at 4.5 VA at 20 °C and picks up reliably from 0.8 to 1.15 times the rated control voltage; drop-out threshold is 0.2 Uc. Minimum switching current is 5 mA at 17 V for the control circuit, so it can handle low-level PLC outputs without issues.
The contactor carries multiple international approvals: EN/IEC 60947-4-1, GB/T 14048.4, UL 60947-4-1, CSA C22.2 No 60947-4-1, and JIS C8201-4-1. These cover the main safety and performance standards for low-voltage switchgear and controlgear. Fire resistance is rated to 850 °C per IEC 60695-2-1, and flame retardance meets Class C2 (NF F 16-101/102) and V1 (UL 94). For safety-related circuits, the B10d value is 1,369,863 cycles at nominal load per EN/ISO 13849-1.
