Legrand TX3 interruptor automático interruptor automático tipo C 1

Single-pole circuit breaker Legrand 403434 rated 16 A at 230 V provides overcurrent protection for residential and light-commercial electrical installations. The device is designed to interrupt faulty currents, protecting wiring and connected equipment from overload and short-circuit conditions. Its compact form factor allows DIN-rail mounting inside standard distribution boards, enabling neat integration and straightforward manual reset after a trip.

Advantages

This single-pole breaker offers consistent thermal-magnetic tripping characteristics suitable for general-purpose circuits. The compact DIN-rail compatible housing reduces panel space usage and simplifies installation. Manual reset functionality provides clear status after activation and allows fast restoration of service once the cause of the trip has been addressed. Construction and contact design are intended to deliver reliable operation over repeated switching cycles.

How to use

Install the breaker on a standard DIN rail inside a distribution board following local electrical codes and safety practices. Connect the incoming phase conductor to the supply terminal and the load conductor to the output terminal, ensuring proper tightening torque on terminals and secure earth and neutral connections in the panel as required. After installation, switch the device to the ON position to energize the circuit; if the breaker trips, identify and rectify the fault or overload before performing a manual reset to the ON position.

Recommendations

Verify compatibility with circuit conductors and downstream device ratings before installation. Use the breaker in circuits with appropriately sized conductors and coordinated protective devices. Periodically inspect terminal tightness and the cabinet environment for dust, moisture, or heat accumulation that can affect performance.
