Legrand 406264 Auxiliary Contact 2NO 2NC Side Mounting for TX3 and DX3

The Legrand 406264 auxiliary contact is a precision-engineered component designed to provide reliable status signaling for electrical distribution systems. Specifically developed for side mounting on TX3 and DX3 series circuit breakers, this device allows for the effective monitoring of circuit states. With its 2NO and 2NC configuration, it offers versatile connectivity options for automation and control applications in both residential and industrial environments, ensuring that system operators receive accurate feedback on the operational status of their electrical installations.

Advantages

This auxiliary contact offers seamless integration with compatible circuit breakers, ensuring a secure and stable connection that maintains the integrity of the electrical panel. The robust design supports long-term operational reliability, reducing the need for frequent maintenance. By providing clear status indication, it enhances the safety and efficiency of circuit management, allowing for rapid response to system changes or faults. Its compact form factor ensures that it does not occupy excessive space within the distribution board, making it an ideal choice for complex electrical setups.

Suitable for

• Monitoring the status of circuit breakers in residential electrical panels
• Industrial automation systems requiring feedback on power distribution
• Integration into smart building management systems for remote monitoring
• Safety-critical applications where circuit state verification is necessary

This device may not be suitable for use with circuit breakers outside of the TX3 and DX3 series, as it is specifically engineered for mechanical and electrical compatibility with these ranges. It is also not intended for direct power switching of high-load equipment, as it serves primarily as a signaling and control interface.

Key specifications

• Configuration: 2 Normally Open (NO) and 2 Normally Closed (NC) contacts
• Mounting type: Side mounting
• Compatibility: Legrand TX3 and DX3 series circuit breakers
• Function: Status signaling and monitoring

Installation should be performed by a qualified professional in accordance with local electrical regulations. The device is mounted to the side of the circuit breaker, ensuring that the mechanical linkage is correctly aligned to detect the breaker's position. Once installed, the electrical connections for the signaling circuit should be wired to the designated terminals, ensuring that the control voltage and current ratings are respected.

What to consider before purchase

• Verify the compatibility of your existing circuit breaker series
• Ensure there is sufficient physical space on the side of the breaker within the distribution board
• Confirm that the control circuit requirements match the contact configuration

For optimal performance and safety, always ensure the main power supply is disconnected before attempting to install or modify the auxiliary contact. Periodically check the terminal connections to ensure they remain tight and free from oxidation.
