LAD8N11 Schneider Electric – TeSys Deca Side-Mounted Auxiliary Contact Block, 1 NO + 1 NC, Screw Clamp Terminals
The Schneider Electric LAD8N11 is an instantaneous auxiliary contact block that clips onto the side of TeSys Deca contactors and CAD control relays. It adds one NO and one NC contact, rated up to 10 A at 690 V AC. Because it mounts on the side, the front of the contactor stays free for a time-delay block, a mechanical latch or another front auxiliary block. The NC contact is mirror-certified, so it can be used to monitor the contactor in safety circuits.
