Schneider Electric LADN223 Auxiliary Contact Block

LADN223 is a TeSys Deca auxiliary contact block that adds four control contacts to a TeSys Deca/TeSys D contour—two normally open (NO) and two normally closed (NC)—so you can extend signaling and interlock capabilities without modifying the main power circuit. Designed for front mounting on TeSys Deca assemblies, this version uses spring terminals for fast, tool-free wiring and reliable connection in control circuits. Ideal for signaling PLC inputs, interlocking between contactor stages, and status feedback within automation and motor-control schemes, it complements Schneider Electric’s TeSys family by providing four discrete, independent contacts in a compact add-on.
