Early auxiliary contact block LC1 2NO screw terminals LADN20

Auxiliary contact block – a reliable extension of contactor functionality

The LADN20 auxiliary contact block is an element that expands the capabilities of contactors from the LC1 series, providing additional control and signaling circuits. Designed to work with LC1D and LC1F models, as well as CAD control relays, it is a key component in the construction of reliable and efficient automation systems. Front mounting with a snap-fit ensures quick and secure installation, minimizing downtime during installation and servicing.

Design and application

The LADN20 block is equipped with two NO (normally open) contacts, which enable the implementation of various control functions. The rated operating current of up to 10A at 230V AC allows connection of medium-power loads, such as valve coils, signal lamps or alarm systems. Screw connection provides solid and durable electrical connections, resistant to vibration and loosening over time. This model is characterized by top mounting, which facilitates access to the terminals during installation and maintenance.

Advantages and benefits for the installer and user

• Versatility: Compatibility with popular LC1D, LC1F contactors and CAD relays means that the LADN20 block can be used in a wide range of industrial applications.
• Simple installation: Front mounting with a snap-fit significantly speeds up the installation process, reducing labor costs and minimizing the risk of errors.
• Reliability: The use of high-quality materials and precise workmanship guarantee long-lasting and trouble-free operation of the contact block.
• Safety: Compliance with many standards (IEC, UL, CSA, CCC, EAC) and the Green Premium certificate confirm the safety of use and care for the natural environment.
• Flexibility: Two NO contacts allow configuration of different control circuits according to the needs of the application.
• Durability: The contact block is designed for frequent switching – up to 1 million switching cycles – which translates to a long device life.
• Easy servicing: Access to the screw terminals is easy, which facilitates diagnostics and repairs in the event of a failure.

The LADN20 block has two normally open contacts with a rated operating current of up to 10A at 230V AC. Mounting is done frontally with a snap-fit, and electrical connections are made using screw terminals.

The LADN20 auxiliary contact block is an optimal solution for professionals looking for a reliable and easy-to-install element that expands the functionality of contactors. Its versatility and high quality of workmanship make it an ideal choice for both new installations and modernization of existing automation systems.
