Coil voltage is the fit gate
The LX1D4G6 is a replacement contactor coil from the Schneider TeSys range, rated for a 120 V AC 60 Hz control circuit. This is the single spec that determines whether the coil pulls in reliably — a 24 V or 48 V coil in the same physical package will not energise on a 120 V line, and a 120 V coil on a lower voltage will drop out under brownout.
TeSys platform and cross-reference
This coil belongs to the LX1D4 platform within the TeSys range, Schneider's standard-duty contactor family. The coil body and mounting dimensions match the LC1D contactor base — verify that the contactor frame size (D-series) accepts the LX1D4 coil before committing the BOM line. The 120 V AC 60 Hz coil suits North American control-voltage conventions common in panel builds.
