note

1. Ensure the circuit breaker is shielded from rainwater during transit and storage. Store it in a well-ventilated environment to maintain its durability.

2. Regularly remove dust and dirt for optimal performance. Use a face mask to expose only the handle of the circuit breaker for safety.

3. Before operation, verify that the technical specifications on the nameplate or markings meet your requirements. The protection features of this circuit breaker are expertly crafted by the manufacturer.

During use, do not disassemble or adjust the circuit breaker without proper guidance.

4. Ensure the neutral wire is correctly connected to prevent any operational issues.

5. Tighten the connecting screw thoroughly before use to ensure secure contact and avoid potential damage.

6. The circuit breaker series is set to operate at a temperature of 30±5 ℃. If multiple units are installed within a sealed box, use them with a reduced capacity.

The capacity reduction coefficient is 0.8.
