## Long description

Legrand TX3 miniature circuit breaker Type C, rated for 20 A and suitable for 240–415 V AC systems (50–60 Hz). It provides overcurrent protection for distribution boards in residential and light commercial installations. The device has an IP20 ingress protection rating and compact dimensions of 70.8 × 77.8 × 88 mm, making it suitable for standard DIN-rail mounting in consumer units and small distribution panels.
Advantages
The TX3 Type C breaker offers reliable overcurrent protection with a C characteristic suitable for protecting general-purpose circuits with moderate inrush currents. Its compact footprint helps save space in distribution boards, and the 4-pole configuration allows protection of three-phase circuits with neutral. The IP20 rating protects against solid objects while remaining intended for indoor enclosure installation.
Suitable for
Residential distribution boards
Light commercial electrical panels
Three-phase circuits requiring neutral protection
Protection of lighting, socket circuits, and small motors with moderate inrush
When it may not be suitable
This breaker is not intended for outdoor installation or environments requiring higher ingress protection, as its IP20 rating only guards against fingers and large solid objects. It also may not be appropriate for circuits with very high motor starting currents or where a different tripping characteristic (e.g., type B or D) is required.
Key specifications
Type: C characteristic (selective for moderate inrush)
Rated current: 20 A
Rated voltage: 240–415 V AC, 50–60 Hz
Number of poles: 4 (three phases + neutral)
Ingress protection: IP20
Dimensions (W × D × H): 70.8 × 77.8 × 88 mm
How to use
Install the breaker on a compatible DIN rail inside an appropriate distribution board by following local electrical codes and safety standards. Connect the incoming supply conductors and outgoing load conductors to the corresponding terminals, ensuring tightening torques and conductor sizes match the installation requirements. Verify the correct wiring for three-phase and neutral connections and test the circuit under no-load conditions before placing into regular service.
What to consider before purchase
Confirm the required tripping characteristic (Type C) is suitable for the connected loads
Ensure 20 A rated current matches conductor sizing and downstream device ratings
Verify IP20 is sufficient for the installation environment (indoor enclosures)
Check dimensions and available DIN-rail space in the distribution board
Usage recommendations
Use the Legrand TX3 C20 breaker in indoor distribution panels for residential or light commercial applications. For circuits with high inrush currents or outdoor installations, select a breaker with an appropriate tripping type or higher ingress protection.
