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

The Schneider Electric LADN22S is a 2NO+2NC front-mounting auxiliary contact block from the TeSys Deca range. Designed to expand signaling and interlocking capability on compatible TeSys D and TeSys Deca contactors, it delivers instantaneous contact operation at up to 690 V AC with a conventional thermal current of 10 A at 60°C. The distinctive red front face (RAL 3000) enables quick visual identification in control panel assemblies.
