Part identity and key ratings
The Schneider LC1K09105R7 is a TeSys K three-pole contactor rated for AC-3 duty at 9 A up to 440 V, with a 440 V AC coil and one normally open auxiliary contact. The AC-3 category means it is designed for starting and stopping squirrel-cage motors under load — the 9 A figure governs the motor current it can switch, not resistive heating. Motor power capability spans 2.2 kW at 220–230 V AC up to 4 kW across 380–690 V AC 50/60 Hz supplies, covering common European and North American line voltages. The AC-4 utilisation category also applies, so the contactor can handle plugging and inching duty cycles where the motor is reversed or jogged under load.
This order code is marked obsolete by the manufacturer. No official successor order code is listed, so a parametric cross-reference to a current TeSys K or TeSys D variant requires verifying the coil voltage, pole count, and auxiliary configuration against the replacement candidate's datasheet.
