Schneider Electric LADN22 Contact Block

LADN22 is a TeSys Deca front-mount auxiliary contact block that adds four auxiliary contacts to a TeSys D contactor assembly: two normally open (NO) and two normally closed (NC). When mounted on TeSys D/Deca‑compatible contactors, it enables signaling and interlock circuits in control panels without increasing enclosure depth, thanks to its front-mount design and screw-clamp terminals. Rated up to 10 A at 600 V, the LADN22 provides four independent contacts in a compact 4-pole block. Documented pin assignments place NO contacts at 53/54 and 83/84, and NC contacts at 61/62 and 71/72, offering clear, repeatable wiring for auxiliary circuits. This Schneider Electric accessory is designed for TeSys D/Deca family (including LC1D/LC1F style contactors) and is wired via sturdy screw clamps for reliable operation in industrial environments. Front mounting allows quick installation on compatible devices, with a robust interface that supports integration within a broader TeSys control system.
