Schneider Electric LADN11 Pushbutton Contact Block

LADN11 is a TeSys Deca auxiliary contact block that provides 1 normally open (NO) and 1 normally closed (NC) contact, designed to mount on LC1D09 to LC1D150 contactors to add signaling or interlock functionality. It is configured for top-mount installation with screw clamp terminals. It is rated for 10 A at up to 690 V AC, making it suitable for standard industrial control circuits. As part of Schneider Electric's TeSys family, LADN11 adds a second pole to the control circuit to monitor or interlock the main contacts. In regional catalogs, a TeSys D variant appears with front-mounting while preserving the 1NO/1NC configuration.
