The LC1K09107P72 is a TeSys K three-pole contactor from Schneider Electric, rated for 9 A in AC-3 utilisation category at ≤440 V. That AC-3 rating governs switching of squirrel-cage motors — the 9 A figure is the current the main poles can make and break under motor starting conditions, not the continuous thermal current. For a 230 V AC coil with built-in bidirectional peak limiting diode suppression, this part was sized into control panels for small motor loads up to 4 kW at 480 V.
Motor power ratings span 2.2 kW at 220–230 V up to 4 kW at 480 V and 660–690 V, all at 50/60 Hz. That 4 kW at 480 V is the typical sizing point for a 5 HP motor on a 480 V three-phase system — the contactor's AC-3 current rating of 9 A is the limiting factor, not the power figure. The 57 mm depth and 45 mm width fit the standard DIN-rail footprint of the TeSys K range, so panel cut-outs and busbar layouts from existing designs carry over.
