Schneider Electric LADN133 Auxiliary Contact Block

The LADN133 is Schneider Electric’s TeSys Deca auxiliary contact block that adds four control contacts to a compatible TeSys Deca contactor: one normally open (NO) and three normally closed (NC) contacts. It is designed for front mounting with spring-terminal connections, enabling tool-free wiring while staying integrated with the TeSys Deca family. Rated for up to 10 A at 690 V AC, this accessory provides four auxiliary contacts to support signaling, interlocking, and feedback in industrial control circuits. Schneider lists LADN133 as discontinued with a last commercial date of September 30, 2026 and recommends LADN13A as the replacement for continued compatibility.
