It provides reliable status signaling for electrical distribution systems, allowing for remote monitoring of switchgear states. This compact accessory is essential for industrial and residential electrical installations requiring enhanced control and diagnostic capabilities.

## Long description

The Legrand auxiliary contact is a precision-engineered 1-pole side-mounted device specifically designed for seamless integration with Legrand TX3 and DX3 series circuit breakers. This component serves as a critical interface for electrical distribution systems, enabling accurate status signaling and remote monitoring of switchgear states. Its compact design ensures it fits efficiently within standard electrical enclosures, providing essential diagnostic feedback for both industrial and residential power management setups.
Advantages
This auxiliary contact offers high reliability in monitoring the operational state of circuit breakers, ensuring that system administrators receive immediate feedback on whether a breaker is open or closed. By facilitating remote status indication, it significantly reduces the need for manual inspections, thereby enhancing the overall safety and efficiency of electrical installations. The side-mounted configuration allows for a space-saving installation that does not interfere with the primary functionality of the circuit breakers, maintaining a clean and organized distribution board layout.
Suitable for
Remote monitoring of circuit breaker status in residential distribution boards
Industrial automation systems requiring feedback on switchgear positions
Electrical installations where enhanced diagnostic capabilities are necessary
Integration into smart home or building management systems for status reporting
When it may not be suitable
This device is not intended for use with circuit breaker series outside of the specified TX3 and DX3 ranges, as compatibility is limited to these models. It is also not suitable for applications requiring power switching or direct control of heavy loads, as it is strictly designed for signaling purposes.
Key specifications
Configuration: 1-pole (1P)
Mounting type: Side-mounted
Compatibility: Legrand TX3 and DX3 series circuit breakers
Function: Status signaling and remote monitoring
How to use
Installation should be performed by a qualified electrician in accordance with local safety regulations. The auxiliary contact is attached to the side of the compatible circuit breaker using the integrated mounting mechanism. Once physically secured, the signaling wires are connected to the terminals of the contact, which then transmit the state of the breaker to a monitoring device or control panel. Ensure that the main power is disconnected before attempting any installation or maintenance on the distribution board.
What to consider before purchase
Verify that your existing circuit breakers belong to the TX3 or DX3 series
Ensure there is sufficient physical space on the side of the breaker within the distribution cabinet
Confirm the requirements of your monitoring system to ensure compatibility with the contact output
Usage recommendations
Always verify the electrical compatibility of the signaling circuit with the auxiliary contact ratings before commissioning. Regular testing of the signaling function during routine maintenance is recommended to ensure continued operational reliability.
