Schneider Electric LADR0 Contact Block

Schneider Electric LADR0 is a TeSys Deca time-delay auxiliary contact block that adds a 1NO+1NC auxiliary pair to TeSys Deca contactors, enabling a controlled off-delay timing of 0.3 to 3 seconds for simple interlocks and sequenced control. This front-mounted accessory uses screw-clamp terminals for secure wiring and mounts on the front of compatible TeSys Deca devices to keep the control layout compact. Designed for industrial and HVAC applications, the LADR0 extends the TeSys D family with a compact, reliable time-delay function without needing a separate relay. Its 1 normally open and 1 normally closed contacts support straightforward interlock logic and delayed activation in control circuits, such as soft-start sequences, timed safety interlocks, conveyors, fans, and pumps. As an AC-coil accessory in Schneider Electric's TeSys Deca lineup, LADR0 is built to integrate with existing control schemes and is part of Schneider's ecosystem for motor control and automation.
