The Schneider Electric LC1K06103K7 is a TeSys K series 3-pole contactor rated for motor control in AC-3 and AC-3e utilisation categories, switching 6 A at 440 V. The 100 V AC coil draws 30 VA inrush and 4.5 VA hold-in at 20 °C. The spring terminals accept 0.75 to 1.5 mm² solid or flexible cable, and the 1 NO auxiliary contact provides a signalling circuit rated down to 5 mA and 17 V.
The AC-3 rating of 6 A at 440 V governs motor switching — it handles the inrush of a small motor up to that current, not just resistive loads. Electrical durability is 1.3 million cycles at 6 A AC-3, dropping to 50,000 cycles at 36 A AC-4 for plugging or inching duty. Mechanical durability is 10 million cycles, so the contactor outlasts its electrical life under normal motor starts. The IP2X finger protection (VDE 0106) means it is safe for open-panel mounting where accidental contact is a concern.
