Advantages
This circuit breaker offers robust construction and precise tripping characteristics, making it a dependable choice for modern electrical installations. Its Type B tripping curve is specifically optimized for circuits with low surge currents, providing a balanced approach to protection. The compact design allows for efficient use of space within distribution boards, while the 6kA breaking capacity ensures that the device can handle significant fault currents without compromising the integrity of the electrical system.
Suitable for
Residential lighting and power circuits
Commercial office electrical distribution
Protection of sensitive electronic equipment
General purpose branch circuit protection
When it may not be suitable
This device is not intended for use in high-surge applications, such as circuits powering large motors or heavy industrial machinery, where a Type C or D tripping characteristic would be required to prevent nuisance tripping. It is also not suitable for outdoor environments without an appropriate weather-resistant enclosure due to its IP20 rating.

How to use
The Legrand TX3 circuit breaker is designed for mounting on a standard DIN rail within a distribution board or consumer unit. Installation should be performed by a qualified electrician to ensure all connections are secure and compliant with local electrical regulations. Once mounted, the device is operated via the front-facing toggle switch, which indicates the status of the circuit. In the event of a trip, the switch will move to the off position, allowing for easy identification and manual reset after the fault has been cleared.
What to consider before purchase
Verify that the 4A rated current is appropriate for the specific load of your circuit.
Ensure the 2-pole configuration matches your system requirements.
Check that the available space in your distribution board accommodates the 35.4 mm width.
Confirm that the Type B characteristic is suitable for the connected equipment.
Usage recommendations
Always ensure that the power supply is disconnected before attempting any installation or maintenance work on the distribution board. Regularly inspect the circuit breaker for signs of wear or damage and test the functionality periodically to maintain optimal safety standards.
