Suitable for
Residential electrical distribution boards
Commercial building power management systems
Protection of lighting and general-purpose socket circuits
Industrial sub-distribution panels
When it may not be suitable
This device is not intended for use in environments with high levels of moisture, dust, or corrosive gases, as it carries an IP20 rating which offers no protection against water ingress. It is also not suitable for applications requiring a higher breaking capacity than 6kA or for circuits with specific high-inrush current loads that would necessitate a Type C or Type D tripping characteristic.

How to use
The Legrand TX3 circuit breaker is designed for professional installation onto a standard DIN rail within an electrical distribution enclosure. Installation should be performed by a qualified electrician in accordance with local electrical codes and safety regulations. Ensure that the supply voltage matches the specifications of the device before mounting. Once securely snapped onto the rail, connect the incoming supply cables to the top terminals and the outgoing load cables to the bottom terminals, ensuring all connections are tightened to the manufacturer's specified torque to prevent overheating.
What to consider before purchase
Verify that the 32 A current rating is appropriate for your specific circuit load.
Ensure the 4-pole configuration is required for your electrical system layout.
Confirm that the 6kA breaking capacity meets the short-circuit current requirements of your installation site.
Check the available space in your distribution board to accommodate the 70.8 mm width of the device.
Usage recommendations
Always ensure the main power supply is disconnected before attempting any installation or maintenance work on the distribution board. Regularly inspect the circuit breaker for signs of physical damage or discoloration, and test the operation periodically to ensure continued safety and functionality.
