Schneider Electric LADN119 Push Button Contact Block

Schneider Electric LADN119 is an auxiliary contact block for TeSys Deca contactors that provides one normally open (NO) and one normally closed (NC) contact, enabling simple signaling and interlock logic in control circuits. It is designed for front mounting on compatible TeSys Deca assemblies and uses Faston terminals for wire connections, which simplifies panel wiring and field connections. This 1NO+1NC block expands the control functionality of TeSys Deca systems by allowing status feedback and basic interlocking within automation panels, supporting clear start/stop signaling and basic sequencing without adding a separate relay. The LADN119 is a discontinued reference, with commercialization ending on October 10, 2020 and end of service on November 4, 2020, and Schneider Electric notes that LADN119 has not been replaced. When selecting accessories for TeSys Deca, verify the 1NO+1NC configuration to match your control scheme and ensure proper wiring practices for auxiliary contacts within your specific application.
