Schneider Electric (Square D) LADN22S Auxiliary Contact Block 2NO & 2NC TESYS SRS

The Schneider Electric (Square D) LADN22S Auxiliary Contact Block TESYS SRS provides additional switching contacts for circuit expansion in electrical assemblies. It converts mechanical switching actions from a contact into additional signaling paths used for monitoring and control logic. The 2NO and 2NC configuration refers to two normally open and two normally closed contact sets that change state during operation to support circuit feedback. In HVAC systems and industrial control panels, it is mounted on compatible contactors to extend signal handling capacity and support coordinated equipment control during operation sequences.
