Schneider Electric LADN20 Auxiliary Contact Block

The auxiliary contact block, also known as auxiliary switch block or extension block, with type number LADN20 from Schneider Electric, is an electrical component that serves to expand the switching contacts of main contactors. It has the dimensions 4 x 4 x 4 cm and weighs 0.035 kg. Auxiliary contact blocks enable the addition of extra switching contacts to contactors to implement control, signaling, or interlocking tasks in electrical circuits. Typical applications are found in automation technology for controlling machines and systems, as well as in building technology for complex switching and signaling functions.
