How to use

Install the breaker on a compatible 35 mm DIN‑rail inside a distribution board following applicable electrical codes and safety standards. Ensure the mains supply is switched off before making connections. Connect the incoming phase conductor to the breaker line terminal and the load conductor to the load terminal, tightening terminals to the recommended torque.
