Part identity and function
The LX4D4BD is a replacement coil for TeSys D-series contactors, operating on a 24 V DC control circuit. It is classified under the TeSys range and carries the device short name LX4D4.
Lifecycle and sourcing reality
Schneider Electric has marked the LX4D4BD as obsolete. No official successor or cross-reference is recorded. Sourcing is through independent surplus channels; quantities are lot-specific and confirmed at RFQ. Let me be transparent — a genuine part is genuine regardless of which region's stock it came from, but the manufacturer warranty geofencing may apply.
Fit and compatibility
This coil mounts onto TeSys D-series contactor bodies. The 24 V DC control voltage is standard for panel-level PLC or relay outputs — verify the contactor frame size and coil terminal arrangement against the existing assembly before committing the BOM line.
