Schneider Electric LADN22 Auxiliary Contact Block

Schneider Electric LADN22 auxiliary contact block is a four-contact add-on for TeSys D and TeSys Deca contactors, delivering two normally open (NO) and two normally closed (NC) contacts in a compact front-mounted module. It mounts on the front of compatible TeSys D/Deca starters and uses screw clamp terminals for secure wiring, enabling straightforward installation and durable connections in industrial control panels. With four signaling contacts, LADN22 supports control applications such as PLC input signaling, interlock schemes, and status monitoring while keeping the main power path of the starter uncluttered. As part of Schneider Electric’s TeSys auxiliary contact family, the LADN22 integrates with TeSys D and TeSys Deca systems to add reliable feedback and control options in space-constrained installations.
