Schneider Electric LADN40 is a TeSys auxiliary contact block that provides four normally open (NO) contacts in a compact add-on module. The front-mount version for TeSys D features screw clamp terminals for secure wiring and is designed to mount on TeSys D contactors, delivering four independent NO signals in a single block. Rated for 10 A at up to 600 V AC, the LADN40 is also available in a top-mount variant for TeSys Deca contactors and is listed as compatible with LC1D09 to LC1D150 contactors in that configuration, supporting signaling, interlocking, and remote status feedback within motor-control panels.
