## Long description

The Schneider Electric LA1KN04 is a high-quality front-mounted auxiliary contact block specifically engineered for seamless integration with TeSys K contactors. This compact component provides four normally closed (NC) contacts, enabling reliable switching operations within control and signaling circuits. Designed for industrial automation, it serves as a critical expansion module that enhances the monitoring and control capabilities of electrical systems, ensuring consistent performance and operational safety.
Advantages
The primary benefit of this auxiliary contact block is its robust design and ease of installation. By mounting directly onto the front of the contactor, it saves valuable space within control panels and electrical cabinets. The use of screw-clamp terminals ensures a secure and durable electrical connection, minimizing the risk of loose wiring and signal interruptions. Its compatibility with the TeSys K series allows for quick system upgrades without the need for extensive modifications, making it an efficient solution for complex industrial setups.
Suitable for
Industrial automation control systems
Signaling and monitoring circuits
Expanding existing TeSys K contactor functionality
Electrical panel building and maintenance
When it may not be suitable
This auxiliary contact block is specifically designed for use with TeSys K contactors and may not be compatible with other contactor series or brands. It is not intended for high-power switching applications, as it is strictly limited to control and signaling circuit duties.
Key specifications
Contact configuration: 4 Normally Closed (NC)
Mounting type: Front-mounted
Connection type: Screw-clamp terminals
Compatibility: TeSys K contactors
How to use
To install the LA1KN04, ensure that the power supply to the contactor is completely disconnected. Align the auxiliary contact block with the front mounting interface of the TeSys K contactor and snap it into place until it is securely locked. Once mounted, connect the control wires to the screw-clamp terminals, ensuring that each wire is tightened to the manufacturer's recommended torque specifications. Verify all connections before restoring power to the system.
What to consider before purchase
Verify that your contactor is part of the TeSys K series
Ensure that your control circuit requires 4 normally closed contacts
Check available space on the front of your existing contactor
Usage recommendations
Always perform a functional test of the auxiliary contacts after installation to ensure they operate correctly in sequence with the main contactor. Regularly inspect the screw-clamp terminals during routine maintenance to ensure connections remain tight and free from oxidation.
