Schneider Electric LADN20 TeSys Auxiliary Contact Block 2NO

The Schneider Electric LADN20 is a TeSys auxiliary contact block designed to provide additional switching interfaces for contactors and control relays in industrial and automation electrical systems. Featuring two normally open (2NO) instantaneous contacts, this block allows easy integration of auxiliary functions such as status signalling, interlocking, and control logic expansion. It mounts on the front of compatible TeSys contactors and other devices, connecting via secure screw-clamp terminals that ensure dependable electrical contact. Rated for up to 10 A at 690 V AC and compliant with relevant IEC/EN standards for auxiliary contacts, the LADN20 offers reliable performance in machine control, panel automation, and signalling applications where expanded auxiliary contact capability is needed. Its compact design promotes efficient use of space in control cabinets and simplifies wiring in complex logic circuits.
