Early-break auxiliary contact block LC1 2NO 2NC screw terminals LADN22

Auxiliary contact block – a reliable extension for TeSys contactors

The LADN22 auxiliary contact block is a dedicated accessory that expands the functionality of Schneider Electric TeSys D and TeSys F contactors. Front-mounted, it provides additional control and signaling circuits, increasing the flexibility and configuration options of electrical installations. Thanks to the combination of two normally open (2NO) and two normally closed (2NC) contacts, this block enables the implementation of various functions, from simple auxiliary circuits to more advanced safety applications.

Functionality and practical application

LADN22 is characterized by instantaneous contact operation, which means an immediate response to changes in the contactor state. This is crucial in applications requiring precise control and fast response to events. The rated operating current of up to 10A at 230V AC (AC-15) makes this block suitable for controlling various loads, such as valve coils, signal lamps or small motors. Front mounting simplifies installation and servicing, and screw connection ensures secure and durable electrical connections.

Advantages for installers and users

• Versatility: Compatible with a wide range of TeSys D and TeSys F contactors, simplifying selection and installation.
• Safety: Can be used in safety applications thanks to the instantaneous contact operation.
• Durability: High quality of workmanship guarantees reliable operation for a long time.
• Easy installation: Front mounting and screw connection simplify installation and servicing.
• Flexibility: The combination of 2NO + 2NC contacts allows for the implementation of various control functions.
• Secure connections: Screw connection ensures stable and safe electrical connections, minimizing the risk of failure due to loose wires.
• Quick identification: Dark gray color facilitates visual identification of the contact block in the installation.
