## Long description

The Legrand TX3 403724 is a high-quality 1-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in both residential and industrial environments. This device is designed to safeguard electrical installations by effectively interrupting the power supply in the event of overloads or short circuits, ensuring the safety of connected equipment and wiring. With a rated current of 32A and a robust 6kA breaking capacity, it is built to handle demanding electrical loads while maintaining consistent performance across a voltage range of 240-415V.
Advantages
This circuit breaker offers exceptional reliability and durability, which are hallmarks of the Legrand brand. Its compact design allows for efficient use of space within electrical distribution boards, making it an ideal choice for modern installations where panel space is limited. The Type D tripping characteristic provides a higher tolerance for inrush currents, making it particularly effective for circuits powering motors, transformers, or other inductive loads that experience temporary current spikes during startup. The device is constructed with high-quality materials to ensure long-term operational stability and safety.
Suitable for
Residential electrical distribution systems
Industrial power distribution panels
Circuits supplying inductive loads such as motors and transformers
Protection against short circuits and overloads
This device may not be suitable for applications requiring a different tripping characteristic, such as Type B or C, which are more sensitive to lower current surges. It is also not intended for outdoor use without a protective enclosure, as it carries an IP20 rating, meaning it is not protected against water ingress or high levels of dust.

How to use
The Legrand TX3 circuit breaker is designed for mounting on a standard DIN rail within an electrical distribution board. Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is snapped onto the rail, and the electrical conductors are secured into the terminal clamps. Ensure that the wire gauge is appropriate for the 32A current rating to prevent overheating. Once installed, the toggle switch can be used to manually disconnect or reconnect the circuit as needed.
What to consider before purchase
Verify that the 32A rating matches the requirements of your specific circuit load.
Ensure that the Type D characteristic is appropriate for the equipment being protected.
Check the available space in your distribution board to accommodate the 17.8 mm module width.
Confirm that the installation environment meets the IP20 protection requirements.
Usage recommendations: Always ensure the power supply is completely disconnected before attempting any installation or maintenance work on the electrical distribution board. Regularly inspect the circuit breaker for signs of wear or damage to maintain optimal safety standards.
