How to use
Install the Legrand Tx3 C20A on a standard DIN rail in the distribution board, ensuring the correct orientation and secure mechanical attachment. Connect the line conductor to the supply terminal and the load conductor to the load terminal, observing proper torque values and local wiring regulations. After wiring, switch the breaker to the ON position and verify circuit continuity and correct protection operation by testing under no‑load conditions. Routine inspection should be performed visually and functionally according to local electrical safety standards.
Usage recommendations
Match the C20A characteristic to the expected load type and inrush currents; for motors or highly inductive loads, verify selectivity and consider a different tripping curve if necessary. Ensure the distribution board and upstream protection coordination comply with applicable electrical codes, and have installation and maintenance performed by a qualified electrician.
