LADN40 Schneider Electric – TeSys Deca Front-Mounted Auxiliary Contact Block, 4 NO, Instantaneous, Screw Clamp Terminals
The Schneider Electric LADN40 is a front-mounted instantaneous auxiliary contact block for TeSys Deca (TeSys D) contactors. It adds four normally open contacts to a contactor, rated up to 10 A at 690 V AC. It clips onto the front of the contactor in seconds without tools and uses screw clamp terminals. It is the quick way to add the extra signalling, interlocking and self-holding contacts a control circuit needs, without fitting a separate control relay.
