What this coil does and where it fits
The LX1D4M5 is a replacement coil for Schneider Electric TeSys D-series contactors, providing the 220-230 V AC 50 Hz control circuit voltage that pulls the contactor in. It is the magnet coil only — not a complete contactor — so you swap it into the existing contactor frame when the original coil fails or when changing the control voltage on a panel rebuild.
Lifecycle reality — obsolete, but sourced
Schneider lists this coil as obsolete. No official successor order code is recorded in the lifecycle data. For a legacy TeSys D installation where the coil has failed or the control voltage needs matching, the LX1D4M5 is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. If you are holding a critical spare for a line that runs on 220-230 V AC control, this is the one-in-the-cabinet part to keep on the shelf before it fails.
Control voltage and fit
Rated 220-230 V AC at 50 Hz — this is the nominal control circuit voltage for the TeSys D contactor frame. The coil draws its inrush and hold current from the 50 Hz line; running it on 60 Hz without verifying the manufacturer's derating is not recommended. The LX1D4 designation tells you it fits the D-series contactor body; the M5 suffix encodes the voltage tap. Mounting is a direct swap onto the existing contactor yoke — no DIN rail or panel mod needed.
