## Long description

The Legrand TX3 miniature circuit breaker is a robust 3-pole electrical protection device engineered to provide reliable safety for both residential and industrial electrical installations. This high-quality component is designed to effectively manage electrical distribution by offering dependable protection against short circuits and overloads, ensuring the integrity of your connected equipment and wiring systems.
Advantages
This circuit breaker stands out due to its precise Type D tripping characteristic, which is specifically optimized for handling high inrush currents often associated with inductive loads like motors or transformers. Its 3-pole configuration allows for the simultaneous disconnection of three phases, providing comprehensive safety in three-phase power systems. The compact design ensures efficient use of space within distribution boards, while the durable construction guarantees long-term operational stability and consistent performance under standard electrical loads.
Suitable for
Industrial machinery and motor control circuits
Three-phase electrical distribution boards
Residential installations with high-start-current appliances
Protection of lighting circuits with high inrush demands
When it may not be suitable
This device is not intended for use in environments exposed to moisture or dust, as it carries an IP20 protection rating. It is also not suitable for circuits requiring Type B or Type C tripping characteristics, as the Type D curve is specifically designed for high-surge applications and may not trip quickly enough for standard household resistive loads.
Key specifications
Rated current: 16A
Tripping characteristic: Type D
Number of poles: 3
Operating voltage: 240-415V
Frequency: 50-60Hz
Protection rating: IP20
Dimensions: 88mm x 53.1mm x 77.8mm
How to use
The Legrand TX3 circuit breaker is designed for professional installation onto a standard DIN rail within an electrical distribution enclosure. Ensure that the power supply is completely disconnected before attempting installation. Secure the device firmly onto the rail and connect the incoming and outgoing power cables to the appropriate terminals, ensuring all connections are tightened to the manufacturer's specified torque to prevent overheating. Once installed, the toggle switch allows for manual control of the circuit state.
What to consider before purchase
Verify that the 16A rating matches your circuit load requirements
Ensure the Type D characteristic is appropriate for your specific equipment
Confirm that your distribution board has sufficient space for a 3-pole device
Check that the operating environment meets the IP20 protection standard
Usage recommendations
For optimal safety and performance, installation should be performed by a qualified electrician in accordance with local electrical regulations. Regularly inspect the device for signs of wear or thermal damage and test the switching mechanism periodically to ensure continued functionality.
