How to use

Install the breaker on a standard DIN rail inside the distribution board following local electrical codes and safety practices. Ensure the supply is isolated before wiring. Connect the line conductor to the input terminal and the load conductor to the output terminal, tightening terminals to the manufacturer’s recommended torque. After wiring, restore supply and test the breaker by switching it on; simulate an overload or use manufacturer test procedures to verify trip function if appropriate. In case of a trip, identify and rectify the cause of overload or short circuit before manually resetting the breaker.

Recommendations

Use this breaker only within its rated current and voltage limits; avoid using it as a switch for frequent operation. Periodically inspect terminals for tightness and signs of overheating, and follow applicable installation standards and local regulations when integrating into an electrical installation.
