Early auxiliary contact block LC1 4NO screw terminals LADN40

Auxiliary contact block LADN40 is a reliable solution for expanding the functionality of TeSys Deca contactors (LC1D, LC1F) and CAD control relays. Designed for applications requiring additional auxiliary contacts, it provides flexibility and safety in electrical circuit control.

Construction and mounting

This block features front mounting, which simplifies its installation and replacement. Screw terminals allow for solid and secure connection of wires up to 2.5 mm², both flexible and rigid, with or without ferrules. A top-mounting model provides convenient access during servicing.

Application and functionality

Equipped with four normally open (NO) contacts, the LADN40 block allows for the implementation of various auxiliary functions in control systems. Its rated operating current of up to 10 A at 230 V AC (AC-15) guarantees reliable operation even in loaded applications. The instantaneous characteristic of the contacts ensures a quick response to changes in circuit state.

Advantages for the installer and user:

• Versatility: Compatible with a wide range of TeSys Deca contactors and CAD relays, simplifying component selection.
• Easy installation: Front mounting and screw terminals facilitate installation and wiring.
• Reliability: High quality workmanship and certifications (IEC, UL, CSA, CCC, EAC) ensure long-lasting and safe operation.
• Flexibility: Four NO contacts allow for configuration of various auxiliary functions in the control system.
• Compliance with standards: The product meets Green Premium requirements (RoHS/REACh), confirming its environmental friendliness.
• Durability: Designed for frequent switching – even up to 1 time per second – and withstands up to 1.5 million switching cycles.
• Built-in mirrored contacts: Allow for the creation of redundant control circuits for increased safety.
