## Summary description

The Legrand 406282 is an undervoltage release accessory designed for use with TX3, DX3, and FRX series circuit breakers.

It is a reliable solution for industrial and residential electrical distribution systems requiring enhanced safety and monitoring capabilities.

## Long description

The Legrand 406282 undervoltage release is a specialized modular accessory engineered to enhance the safety and functionality of electrical distribution systems. Designed for seamless integration with TX3, DX3, and FRX series circuit breakers, this device provides critical protection by automatically triggering a trip when the supply voltage falls below a predetermined threshold. It serves as an essential component for maintaining system integrity in both residential and industrial environments where voltage stability is paramount.
Advantages
This undervoltage release offers a robust solution for remote monitoring and protection. Its design allows for tool-free installation, enabling quick and efficient attachment to the side of compatible circuit breakers. The unit supports the use of supply busbars, ensuring that the electrical installation remains organized and compliant with professional standards. By facilitating remote tripping via a normally closed push button or automatically during a voltage drop, it provides a versatile layer of control for complex electrical setups.
Suitable for
Residential electrical distribution boards
Industrial power management systems
Applications requiring remote emergency shutdown
Systems where automatic protection against voltage drops is necessary
When it may not be suitable
This device is intended exclusively for use with specific Legrand product series, including TX3, DX3, and FRX. It is not compatible with circuit breakers from other manufacturers or older product lines not explicitly listed. Furthermore, it is designed for a 230V AC environment and should not be used in systems operating at different voltage levels.
Key specifications
Operating voltage: 230 V AC
Compatibility: TX3, DX3, and FRX series
Mounting position: Left-hand side of the device
Width: 1 module
Dimensions: 86 mm x 98 mm x 26 mm
Maximum capacity: 1 remote tripping auxiliary per device
How to use
The installation process is designed for simplicity and does not require specialized tools. The unit is mounted on the left-hand side of the main circuit breaker, RCBO, or RCCB. Once physically joined, the auxiliary device is ready to monitor the supply voltage. It can be triggered automatically by a drop in mains voltage or manually by integrating a normally closed push button into the circuit, allowing for immediate remote disconnection of the associated breaker.
What to consider before purchase
Verify that your existing circuit breaker is part of the TX3, DX3, or FRX series.
Ensure there is sufficient space in your distribution board for one additional module.
Confirm that your system operates at the required 230V AC voltage.
Check that you are not exceeding the limit of one remote tripping auxiliary per device.
Usage recommendations
For optimal performance and safety, ensure that all electrical connections are tightened according to standard electrical installation practices. Always disconnect the main power supply before attempting to install or modify any components within your distribution board.
