It uses screw-clamp terminals accepting 1 to 4 mm² conductors and mounts to the front of TeSys D, TeSys Deca, and TeSys F contactors and reversing contactors. As an add-on block, the LADN20R extends the control-circuit I/O of the base contactor without additional wiring to the main power poles. The 2 NO contacts close when the contactor coil energises, providing a dry signal for PLC inputs, status lamps, or interlocking logic. Rated making capacity reaches 140 A AC and 250 A DC per IEC 60947-5-1, with a permissible short-time rating of 100 A for 1 second at 60 °C — figures that cover inrush from pilot devices and small solenoids. ## Applications Auxiliary contact blocks of this class are used across motor control centres, conveyor systems, pump panels, and HVAC equipment to signal contactor state back to a controller or to chain multiple contactors in a sequence. The LADN20R fits panels where only normally-open status feedback is needed — for example, a run indication on a starter or a permissive signal for a downstream device. The LADN20R is officially discontinued by Schneider. No direct replacement part number has been published. For existing installations, sourcing from surplus or broker channels is the typical route; an RFQ will confirm current availability and lead time. Buyers with active BOMs should evaluate the LADN20A (2 NO + 2 NC) as a functional alternative, noting the additional NC contacts.","metaTitle":"Schneider LADN20R TeSys Deca Auxiliary Contact Block 2NO","metaDescription":"Schneider TeSys Deca LADN20R auxiliary contact block, 2NO, 6 A, screw-clamp terminals, 690 V, IP2X.
