Legrand TX3 interruptor automático miniatura tipo C 1

Legrand Tx3 C10A is a single-pole miniature circuit breaker with a C tripping characteristic and a rated current of 10 A. With a breaking capacity of 6 kA and a compact 1-module width, this device is intended for overcurrent and short-circuit protection in residential and commercial electrical installations. The breaker is suitable for installation on standard DIN rails in distribution boards and is typically used to protect individual circuits such as lighting, socket outlets and small appliance circuits.

Advantages

The Tx3 C10A provides reliable thermal-magnetic protection with a C characteristic that balances sensitivity to moderate inrush currents and quick response to sustained overloads or short circuits. Its 6 kA breaking capacity meets common installation requirements for domestic and light commercial environments. The single-module format saves space in distribution boards while allowing straightforward DIN-rail mounting and integrated terminal connections for simplified wiring.

Key specifications

How to use

Install the breaker on a standard 35 mm DIN rail inside the distribution board. Connect the live (phase) conductor to the breaker’s input terminal and the outgoing load conductor to the output terminal, ensuring all connections are tightened to the manufacturer’s recommended torque values. Verify the neutral and earth conductors are properly connected in the distribution board. After wiring, switch the breaker to the ON position and test the circuit for correct operation. Use appropriate isolation and follow local electrical codes when working on the installation.

Recommendations

Choose this C10A breaker for circuits with moderate inrush currents such as lighting with electronic ballasts or small motors. Do not exceed the rated current and ensure upstream fault current capacity is compatible with the 6 kA breaking rating. For circuits requiring residual-current detection or selective coordination, combine this breaker with appropriate RCDs or system-level protection as required by regulations.
