Description
The Schneider Electric (Square D) LADN20 Front Mount Auxiliary Contact is an electrical switch used to expand the contact capabilities of main contactors. It provides two normally open contact points that change state in coordination with the primary part, allowing additional circuit control and signaling. This auxiliary contact is commonly mounted on the front of compatible contactors in control panels, motor starters, and automation assemblies. Within HVAC systems, it is used in control circuits to provide status feedback or enable interlocking between components. Its compact front-mounted structure allows direct integration without modifying existing control layouts.
