Early-break auxiliary contact block LC1 3NO 1NC screw terminals LADN31

Auxiliary contact block – a reliable extension for TeSys Deca contactors

This LADN31 auxiliary contact block is a key element for expanding the functionality of LC1D and LC1F contactors, as well as CAD control relays. It allows you to add additional auxiliary contacts to the circuit, which translates into greater flexibility and control options. Front mounting with snap-in ensures quick and secure installation, minimizing downtime.

Construction and operating parameters

The LADN31 block offers a configuration of 3NO (normally open) and 1NC (normally closed) contacts. Screw terminals provide solid and reliable electrical connections. A rated current of 10A at AC-15, 230V confirms its ability to operate in demanding applications. A top-mounting model facilitates access and configuration inside control cabinets.

• Universality: Compatible with a wide range of TeSys Deca contactors (LC1D, LC1F) and CAD relays.
• High reliability: Front mounting with snap-in guarantees a stable connection and long-term operation.
• Flexibility: 3NO + 1NC configuration allows adaptation to specific application needs.
• Durability: Designed for frequent switching – even up to 1 time per second.
• Safety: Has certificates of compliance with many standards (IEC, UL, CSA, CCC, EAC) and meets Green Premium requirements (RoHS/REACh), ensuring compliance with environmental regulations.
• Mirror contacts: Built-in mirror NC contacts increase the safety and functionality of the control system.

The LADN31 block is not only an element expanding the capabilities of the contactor, but also an investment in the reliability and durability of the entire control system. Its solid construction and high quality of workmanship guarantee long-term trouble-free operation even in difficult industrial conditions. Additionally, meeting the Green Premium requirements demonstrates a responsible approach to the natural environment.
