Schneider Electric LADN22 Auxiliary Contact Block

The auxiliary contact block, also known as additional contacts, auxiliary contact module or auxiliary block, from Schneider Electric with type number LADN22 is an electrical component for extending contactors. It has dimensions of 4 x 4 x 4 cm and weighs 0.1 kg. Auxiliary contact blocks extend the functionality of main contactors by providing additional normally open and normally closed contacts for control and signaling purposes. They enable the implementation of more complex control logics and increase flexibility in electrical circuits. Typical applications can be found in automation technology, mechanical engineering and building technology, where they are used for status reporting of contactors, for interlocking operating states or for controlling auxiliary functions.
