How to use

Install the breaker on a standard DIN rail inside the distribution board, ensuring correct connection of the three phase conductors to the line terminals and loads to the load terminals. Verify the voltage and current rating match the installation requirements before energizing. After wiring, switch the breaker to ON and confirm proper operation and absence of faults in the protected circuit.

Recommendations

Use this Legrand Tx3 C16A 3P breaker in circuits where a type C characteristic is appropriate—typically lighting, socket circuits, and small motor loads—and coordinate it with upstream and downstream protection devices. Follow local electrical codes and have installation or modifications performed by a qualified electrician.
