The Schneider Electric LC7K0610D7 is a TeSys K contactor, 3P, rated AC-3 ≤440 V 6 A, with 1 NO auxiliary contact and a 42 V AC coil. It is now classified as obsolete by the manufacturer.
The AC-3 utilisation category means this contactor is designed for starting and stopping squirrel-cage motors — the 6 A rating at ≤440 V AC governs the motor current it can handle under those conditions. For motor power, it covers 1.5 kW at 220...230 V AC, 2.2 kW at 380...415 V AC, and up to 3 kW at 480 V AC or 660...690 V AC, all at 50/60 Hz. The 3-pole configuration with 3 NO main contacts suits standard three-phase motor control. The single NO auxiliary contact provides feedback or interlocking without an add-on block. Heat dissipation is 3 W, which is modest for panel thermal budgeting. The part carries V1 flame retardance per UL 94 and meets NF F 16-101 and NF F 16-102 requirements, relevant for rail or other fire-safety-sensitive installations.
Integration notes
The 42 V AC coil is a less common control voltage; verify the control transformer tap or supply before committing the BOM line.
