Early-break auxiliary contact block LC1 4NC screw terminals LADN04

Auxiliary contact block – a reliable extension for TeSys contactors

The LADN04 auxiliary contact block is a key element for expanding the functionality of LC1D and LC1F series contactors, as well as CAD control relays. Designed by Schneider Electric, this module provides additional NC contacts, essential in applications requiring an increased number of control and signaling points. Front mounting with a snap-on mechanism guarantees a quick and secure installation method, minimizing system downtime.

Functionality and application

The LADN04 block is equipped with 4 normally open (NC) contacts, designed to operate with a load of up to 10A at 690V AC. This makes it ideal for control circuits, protection, and signaling the operating status of devices. The use of screw terminals ensures solid and durable electrical connections, resistant to vibrations and temperature changes. This is a solution particularly appreciated by installers due to its ease of installation and reliable operation.

Characteristics and benefits

• High reliability: Construction based on proven Schneider Electric components guarantees long-term and trouble-free operation.
• Easy installation: Front mounting with a snap-on mechanism significantly speeds up the installation process, reducing labor costs.
• Versatility: Compatible with popular LC1D, LC1F contactors and CAD relays, increasing the flexibility of control system design.
• Safety: Compliance with many standards (IEC, UL, CSA, CCC, EAC) and Green Premium certification (RoHS/REACh) confirm a high level of safety and environmental care.
• Durability: Robust construction provides resistance to environmental conditions prevailing in industrial plants.
• Cost optimization: The ability to expand existing contactors without having to replace the entire device allows for optimization of investment costs.

The LADN04 block is not only an element that expands the functionality of the contactor – it is an investment in the reliability and safety of the entire control system. Its solid construction and ease of installation make it an ideal choice for both professional installers and end-users looking for proven solutions.
