What this part is
The Schneider Electric LC1K0910UE7 is an IEC-rated contactor from the TeSys K series, specified for 575 VAC and 9 A. It carries the description "CONTACTOR 575VAC 9AMP IEC +OPTIONS," confirming its role as a compact switching device for motor and resistive loads in control panels.
What the ratings mean for fit
The 9 A rating at 575 VAC governs the continuous current the main poles can carry. For motor switching, this contactor is sized for IEC utilization categories — typically AC-3 for squirrel-cage motors up to roughly 3 kW at 400 V, or AC-1 for resistive loads at the full 9 A. The 575 VAC coil voltage (the "UE7" suffix indicates the coil code) means the pickup and dropout characteristics are matched to 575 V control circuits, common in North American 600 V class installations.
Panel integration
The TeSys K form factor snaps onto standard 35 mm DIN rail. The +options suffix indicates the contactor ships with a factory-fitted auxiliary contact block or other add-on — verify the specific option code when ordering to match the existing panel layout.
