Product information

Description

The Legrand TX3 miniature circuit breaker is a professional-grade electrical protection device engineered to safeguard circuits against overcurrents. Designed for reliability and precision, this 3-pole breaker ensures consistent performance in both residential and commercial electrical systems. It operates effectively within a voltage range of 240-415 V and is built to meet the rigorous demands of modern electrical infrastructure.

Advantages

This circuit breaker offers exceptional build quality and consistent tripping performance, which is essential for maintaining the integrity of electrical installations. Its Type B tripping characteristic provides a balanced response to overcurrent conditions, making it a dependable choice for protecting sensitive equipment and wiring. The compact design allows for efficient use of space in distribution boards, while the robust construction ensures long-term operational stability.

Suitable for

  • Residential electrical distribution boards
  • Commercial building power systems
  • Protection of lighting circuits
  • General low-current electrical installations

This device may not be suitable for applications requiring high inrush current tolerance, such as starting large motors or heavy industrial machinery, where a Type C or D breaker might be necessary. It is also not intended for outdoor use without a protective enclosure, as it carries an IP20 rating.

Key specifications

  • Rated current: 1 A
  • Voltage range: 240-415 V
  • Frequency: 50-60 Hz
  • Tripping characteristic: Type B
  • Number of poles: 3
  • Protection rating: IP20
  • Dimensions: 88 mm x 53.1 mm x 77.8 mm

How to use

The circuit breaker should be installed by a qualified electrician into a standard DIN rail distribution board. Ensure that the power supply is disconnected before installation. The device snaps securely onto the rail, and the input and output cables should be connected to the appropriate terminals, ensuring that all connections are tightened to the manufacturer's specified torque settings to prevent overheating.

What to consider before purchase

  • Verify that the 1 A current rating matches your circuit requirements.
  • Ensure the 3-pole configuration is compatible with your electrical system.
  • Check that the installation environment is dry and free from dust, as the device is rated IP20.
  • Confirm that the Type B characteristic is appropriate for the connected load.
Usage recommendations: Regularly inspect the circuit breaker for signs of wear or thermal damage. It is recommended to perform periodic testing of the tripping mechanism to ensure continued protection of your electrical circuits.

Design

International Protection (IP) code: The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
