Product information

Description

Legrand TX3 miniature circuit breaker Type B, rated 50 A, designed for supply voltages from 240 to 415 V and 50–60 Hz, provides overcurrent protection for three-pole circuits in residential and light commercial installations. The device features Type B tripping characteristics suitable for circuits with predominantly resistive loads and offers IP20 protection against contact with live parts. Compact dimensions (W 53.1 mm, D 77.8 mm, H 88 mm) allow installation in standard distribution boards and modular switchgear.

Advantages

The breaker provides reliable overcurrent protection with predictable Type B tripping behaviour, allowing fast disconnection on low levels of fault current while maintaining selectivity with upstream protection. Its compact, modular form factor simplifies mounting in multi-way consumer units and helps save space in crowded panels. IP20-rated enclosure ensures basic protection against accidental contact during routine installation and servicing.

Suitable for

  • Residential distribution boards and home electrical circuits
  • Small commercial premises and light-duty electrical installations
  • Protection of circuits with mainly resistive loads (lighting, heaters, small motors)
  • Three-phase branch circuit protection where Type B tripping is required

Key specifications

  • Rated current: 50 A
  • Rated supply voltage: 240–415 V
  • Frequency: 50–60 Hz
  • Poles: 3 (three-pole)
  • Tripping characteristic: Type B
  • Degree of protection (housing): IP20
  • Mounting: DIN-rail compatible modular device
  • Dimensions (W × D × H): 53.1 mm × 77.8 mm × 88 mm

How to use

Install the Legrand TX3 Type B breaker on a compatible DIN rail inside the distribution board according to local electrical standards and wiring diagrams. Connect conductors to the line and load terminals, ensuring correct tightening torques and secure connections. Verify correct orientation and that the breaker rating matches the circuit conductors and downstream devices. After installation, test the circuit under no-load conditions and verify that the breaker switches correctly and provides expected overcurrent protection.

Usage recommendations

Use this breaker for circuits with predominantly resistive loads and where Type B tripping characteristics are specified. Match the 50 A rating to conductor size and downstream equipment, and coordinate with upstream protection to maintain selectivity. Ensure installation and commissioning are performed by a qualified electrician and that periodic inspection follows applicable regulations.
