The Schneider LC1K06105G7 is a TeSys K three-pole contactor rated for AC-3 and AC-4 duty, meaning it switches motor loads — not just resistive heaters. The AC-3 rating of 6 A at ≤440 V covers small three-phase motors up to 1.5 kW at 230 V or 2.2 kW at 400 V, and up to 3 kW on 480 V and higher supplies. The 120 V AC coil pulls in reliably on the control voltage you'd expect from a standard panel transformer.
The 6 A rating is the operational current in AC-3 category — the one that governs motor switching. The short-time withstand current (Icw) of 90 A for 1 second means it can ride through a locked-rotor inrush without welding contacts. Heat dissipation is only 1.3 W, so you can pack it tight on a DIN rail without cooking adjacent devices.
