## Long description

The Legrand TX3 403537 is a high-quality 3-pole miniature circuit breaker engineered to provide reliable protection for electrical circuits. Designed for precision and safety, this device effectively monitors current flow to prevent damage from overloads and short circuits. It is built to operate within a voltage range of 240-415V and is compatible with standard 50-60Hz electrical systems, making it a versatile component for modern electrical distribution boards.
Advantages
This circuit breaker offers exceptional reliability due to its robust construction and adherence to international safety standards. The Type C tripping characteristic ensures that the device can handle moderate inrush currents, which is ideal for circuits powering inductive loads. Its compact 3-pole design allows for efficient space utilization within distribution panels while maintaining high performance and consistent protection levels across all three phases.
Suitable for
Industrial electrical distribution systems
Residential power distribution boards
Protection of lighting and control circuits
Commercial building electrical infrastructure
When it may not be suitable
This device is not intended for use in environments with high moisture or dust levels, as it carries an IP20 protection rating. It is also not suitable for applications requiring a different tripping curve, such as Type B for purely resistive loads or Type D for high-inrush motor starting currents.

How to use
The Legrand TX3 circuit breaker is designed for installation on a standard DIN rail within an electrical enclosure. It should be installed by a qualified electrician in accordance with local electrical codes. Ensure that the supply power is disconnected before mounting the device. Once securely snapped onto the rail, connect the input and output cables to the corresponding terminals, ensuring that all connections are tightened to the manufacturer's specified torque to prevent overheating.
What to consider before purchase
Verify that the 1A rated current matches your specific circuit load requirements.
Ensure the 3-pole configuration is compatible with your three-phase electrical system.
Check that the installation environment meets the IP20 protection requirements.
Confirm that the Type C tripping characteristic is appropriate for the connected equipment.
Usage recommendations
Always ensure that the total load on the circuit does not exceed the 1A rated current of the breaker to avoid nuisance tripping. Periodically inspect the terminals for tightness and ensure the enclosure remains free of debris.
