## Long description

Legrand TX3 miniature circuit breaker Type D with a rated current of 4 A provides overcurrent and short-circuit protection for single-pole branch circuits. Designed to operate on supplies from 240 to 415 V at 50–60 Hz, this compact DIN-rail device features IP20 protection and a slim 17.8 mm module width, making it suitable for installations with limited panel space.
Advantages
The Type D tripping characteristic allows reliable protection for circuits with moderate inrush currents, such as motors, transformers and certain lighting loads while still responding to fault currents. Its compact dimensions and standard DIN-rail mounting simplify integration into distribution boards and subpanels. The breaker offers clear mechanical operation and a consistent trip response within the specified voltage and frequency range.
Suitable for
 Protection of single-phase branch circuits in residential and commercial electrical panels
 Circuits with equipment that generate moderate starting currents (small motors, control transformers)
 Retrofit installations where space is limited and a slim DIN-rail breaker is needed
Key specifications
 Type: D trip curve
 Poles: 1 (single-pole)
 Rated current: 4 A
 Rated voltage range: 240–415 V AC
 Rated frequency: 50–60 Hz
 Degree of protection: IP20
 Dimensions (W×D×H): 17.8 × 77.8 × 88 mm

How to use
Install the breaker on a compatible DIN rail inside the distribution board following applicable electrical codes and safety practices. Connect the supply conductor to the line terminal and the load conductor to the load terminal, ensuring tight and secure terminations. Verify that the system voltage falls within the 240–415 V range and that the breaker is appropriate for the circuit load and anticipated inrush currents. After wiring, switch the breaker to the ON position and test the protected circuit for correct operation.
Usage recommendations
Use this Type D 4 A breaker where moderate inrush currents occur and where selective coordination with downstream protection is required. Confirm compatibility with upstream protection devices and adhere to local regulations for breaker selection, derating, and thermal management. Periodically inspect terminations and mechanical operation as part of routine maintenance.
