Schneider Electric LADN22 Auxiliary Contact Block

LADN22 is Schneider Electric's TeSys Deca auxiliary contact block engineered for front mounting on TeSys Deca contactors, adding two normally open and two normally closed contacts to the control circuit without altering the main power path; it is designed for use with TeSys Deca ranges such as LC1D and LC1F, and it can be integrated into existing TeSys Deca assemblies to provide expanded signaling, interlock, and feedback options in industrial automation cabinets. The block uses screw clamp terminals for secure, field-wiring connections and is rated up to 10 A at up to 600 V, making it suitable for control logic, status indication, or interlocking functions in a wide range of automation projects. The four contacts are arranged as two NO and two NC, with terminal designations typically assigned to NO at 53/54 and 83/84 and NC at 61/62 and 71/72, aligning with Schneider Electric's auxiliary block conventions and facilitating straightforward documentation and wiring diagrams. Front mounting and compact form factor help minimize panel space while preserving reliability, and the LADN22 complements the TeSys Deca ecosystem by enabling precise control signals that operate independently of the main power contacts.
