Early-break auxiliary contact block LC1 1NO 3NC screw terminals LADN13

Auxiliary contact block – a reliable extension for TeSys contactors

This leading auxiliary contact block, designed to work with LC1D and LC1F contactors and CAD control relays, is a key element in building reliable and safe control systems. It provides additional contacts, increasing the functionality of existing installations and enabling the implementation of more complex control algorithms. Front mounting with snap-in mechanism guarantees quick and secure installation, minimizing downtime during installation and maintenance.

Functionality and parameters

The contact block offers a configuration of 1NO (normally open) and 3NC (normally closed), allowing for versatile use in various applications. The rated current of 10A at AC-15 230V load ensures compatibility with a wide range of loads. Screw connection provides solid and durable electrical connections, minimizing the risk of errors and failures. The design of the contact block has been designed for easy integration with existing control systems, and its compact dimensions allow for mounting in limited space.

Application and benefits

The LADN13 contact block finds application in a wide spectrum of industrial applications, such as:

• Motor control: Additional contacts enable the implementation of advanced motor control functions, such as star-delta starting or overload protection.
• Building automation: Used in building automation systems to control lighting, heating, ventilation and air conditioning.
• Alarm systems: Can be used in alarm systems to signal emergency conditions or malfunctions.
• Manufacturing industry: Ideal for applications in production lines where high reliability and precise control are required.

It is worth emphasizing that the product meets stringent safety standards (IEC, UL, CSA, CCC, EAC) and has a Green Premium certificate (RoHS/REACh), which guarantees its compliance with environmental regulations and a responsible approach to production. Built-in mirrored NC contacts increase the safety of the system operation by providing redundancy. Thanks to the high switching frequency (1 time per second), the contact block works perfectly in dynamic applications.
