Description
Schneider Electric LADN22 TeSys D Auxiliary Contact Block is a component commonly used in electrical systems and control panels. 2NO + 2NC is the configuration of the auxiliary contacts. "NO" stands for Normally Open, which means the contacts are open when not actuated, and they close when actuated.
"NC" stands for Normally Closed, which means the contacts are closed when not actuated and open when actuated. Front Mounting is designed to be attached to the front panel or surface of a control panel or electrical enclosure. Screw Terminals is the type of terminals used for wiring connections. In this case, the auxiliary contact block has screw terminals, which means you would secure the wires by tightening screws.
Overall, Schneider Electric LADN22 TeSys D Auxiliary Contact Block provides two options for electrical connections.
