Industrial LADN313 NSNBC01 Programmable Logic Controller

LADN313 is an auxiliary contact block for Schneider Electric TeSys D/Deca contactors that provides three normally open (NO) contacts and one normally closed (NC) contact to extend a control circuit. Catalog number LADN313; designed to add signaling and interlocking points without changing the main contactor, it mounts to TeSys D/Deca assemblies and is commonly used with LC1D09 to LC1D150 series contactors. Available variants include a front-mount, spring-terminal version in some regions and a top-mount, screw-clamp version used in TeSys Deca applications, reflecting different installation preferences. In certain markets, Schneider Electric lists a last-sale date for LADN313 of September 30, 2026, indicating regional discontinuation. The product is designed to support control logic in motor-control and automation panels, preserving the compact footprint of the TeSys family, and sustainability data on some regional pages indicates a total lifecycle carbon footprint around 5 kg CO2 eq for the accessory. Catalogued under TeSys accessories, LADN313 is the dedicated 3NO+1NC auxiliary block that complements Schneider Electric’s TeSys D/Deca line for enhanced monitoring and interlocking in industrial control schemes.
