Product information

Description

The Legrand TX3 miniature circuit breaker is a high-quality, single-pole electrical protection device engineered to safeguard residential and commercial circuits. With a rated current of 20 A and a robust 10kA breaking capacity, this component effectively detects and interrupts overcurrents, preventing damage to wiring and connected appliances. It is designed to operate reliably within standard 240-415 V AC electrical systems at frequencies of 50-60 Hz.

Advantages

This circuit breaker offers exceptional reliability and safety for modern electrical installations. Its Type B tripping characteristic makes it particularly suitable for circuits with low inrush currents, ensuring precise protection against overloads and short circuits. The compact design allows for efficient use of space in distribution boards, while the durable construction ensures long-term performance and consistent operation under standard environmental conditions.

Suitable for

  • Residential lighting and socket circuits
  • Commercial office power distribution
  • Protection of general-purpose electrical appliances
  • Small-scale industrial control panels

When it may not be suitable

This device is not intended for circuits with high inrush currents, such as those powering large motors or transformers, where a Type C or D characteristic would be required. It is also not suitable for outdoor environments without a protective enclosure, as it carries an IP20 rating.

Key specifications

  • Rated current: 20 A
  • Number of poles: 1
  • Tripping characteristic: Type B
  • Breaking capacity: 10kA
  • Voltage rating: 240-415 V AC
  • Frequency: 50-60 Hz
  • Protection rating: IP20
  • Dimensions: 17.8 mm x 77.8 mm x 88 mm

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 in accordance with local electrical regulations. Ensure that the supply voltage and load requirements match the specifications of the device before connection. The toggle switch on the front allows for manual switching and provides a clear visual indication of the circuit status.

What to consider before purchase

  • Ensure the 20 A rating is appropriate for the specific circuit load
  • Verify that the Type B characteristic matches the connected equipment requirements
  • Confirm that the installation environment is dry and protected, meeting the IP20 standard
  • Check available space in the distribution board for the 17.8 mm wide module

Usage recommendations

Regularly inspect the distribution board for signs of wear and ensure that all terminal connections remain tight to prevent overheating. If the breaker trips, investigate the cause of the overload or short circuit before resetting the device.
