Description
Schneider Electric LADN40 TeSys D Auxiliary Contact Block is a component used to extend the functionality of a primary switching device, such as a contactor or a relay. It has four Normally Open (NO) contacts. This means that in its default state (when not actuated), the contacts are not connected, and when the auxiliary contact is actuated (triggered), the contacts close and create an electrical connection.
The contact block is designed to be attached or mounted on the front surface of a control panel or enclosure. It uses screw-type terminals for wiring connections. These terminals are designed to secure the wires in place by tightening screws, providing a reliable electrical connection.
Overall, Schneider Electric LADN40 TeSys D Auxiliary Contact Block is commonly used in electrical control circuits to monitor or control the status of a device or equipment. The fact that it has four Normally Open contacts means it can be used to monitor or control multiple circuits simultaneously.
