Product information

Description

The Schneider Electric LA1KN40 is a high-quality front-mounted auxiliary contact block specifically engineered for seamless integration with TeSys K contactors. This component provides four normally open (NO) contacts, enabling the expansion of control circuit capabilities in industrial automation environments. Its compact design ensures it fits efficiently into space-constrained electrical panels while maintaining robust performance for signal switching and monitoring tasks.

Advantages

This auxiliary contact block offers exceptional reliability and ease of installation due to its front-mounting design, which allows for quick attachment to compatible contactors without requiring additional side space. The use of high-grade materials ensures long-term durability and consistent electrical connectivity, which is critical for maintaining the operational integrity of complex control systems. By providing four additional switching points, it significantly enhances the flexibility of your automation setup, allowing for more complex logic and feedback loops within a small footprint.

Suitable for

  • Industrial automation control panels
  • Motor control and protection systems
  • Signal switching in low-voltage circuits
  • Monitoring and feedback loops in electrical installations

When it may not be suitable

This component is designed exclusively for use with the TeSys K series contactors and will not be compatible with other contactor lines or brands. It is not intended for high-power switching applications, as it is strictly an auxiliary device for control signals.

Key specifications

  • Contact configuration: 4 normally open (NO)
  • Mounting type: Front-mounted
  • Compatibility: TeSys K contactors
  • Function: Auxiliary signal switching

How to use

To install the LA1KN40, ensure that the power supply to the contactor is completely disconnected to prevent electrical hazards. Align the auxiliary contact block with the front mounting interface of the TeSys K contactor. Press the block firmly until it clicks into place, ensuring a secure mechanical and electrical connection. Once installed, wire the control circuit leads to the designated terminals according to your system schematic. Verify the connections are tight before restoring power to the system.

What to consider before purchase

  • Verify that your existing contactor is part of the TeSys K series.
  • Ensure that your control circuit requires 4 normally open contacts.
  • Check available space on the front of your contactor for mounting.

Usage recommendations

Always perform a functional test of the auxiliary contacts after installation to ensure they actuate correctly in synchronization with the main contactor.
