Schneider Electric LADN22 Auxiliary Contact Block

Schneider Electric LADN22 is a front‑mounted auxiliary contact block for TeSys D and TeSys Deca contactors that provides two normally open (NO) and two normally closed (NC) contacts to extend control and signaling capabilities in motor and machine circuits. It uses screw‑clamp terminals for straightforward wiring and is designed to mount on compatible TeSys D/Deca frames, adding auxiliary contacts without altering the main contactor’s footprint. The 2NO+2NC configuration supports wiring schemes for feedback signals, interlocking, PLC inputs, and other control logic, enabling more versatile control logic and safer sequencing in industrial automation. Electrical performance is suitable for typical control circuits, with a maximum current rating of up to 10 A AC in standard applications, helping ensure reliable sensing and interlock functionality in demanding environments. As part of Schneider Electric’s TeSys auxiliary family, LADN22 is intended for front mounting on eligible TeSys D or TeSys Deca assemblies, delivering a compact, add‑on solution when extra auxiliary contacts are required for signaling, control, or safety interlocks in equipment and panel designs.
