Schneider Electric LADN22S TeSys Deca Auxiliary Contact Block 2NO+2NC

The Schneider Electric LADN22S is a TeSys Deca series auxiliary contact block designed to expand the signalling and control capabilities of contactors and control relays. Featuring two normally open (2NO) and two normally closed (2NC) instantaneous contacts, it provides flexible contact configurations for interlocking, status feedback and safety chain functions. The LADN22S mounts on the front of compatible TeSys contactor bases and connects via secure screw-clamp terminals for reliable electrical connection. Suitable for use with LC1D, LC1F and other TeSys control devices, this auxiliary block is certified to relevant IEC and international standards for contact reliability and endurance. Its compact clip-on design and red front face make it easy to integrate into industrial and automation panels where clear contact feedback and control logic extension are needed.
