7. Вирішення проблем

If you encounter issues with your Eaton FAZ-C10/3-NA circuit breaker, consider the following common scenarios:

7.1 Часті спрацьовування автоматичного вимикача

• Перевантаження: The circuit may be drawing more current than the breaker's 10A rating. Reduce the load on the circuit.
• Коротке замикання: A direct connection between live and neutral/ground wires. This requires immediate investigation by a qualified electrician.
• Несправний прилад: Disconnect appliances one by one to identify a faulty device.

7.2 Автоматичний вимикач не скидається

• Ensure the handle is pushed fully to the 'OFF' position before attempting to reset to 'ON'.
• If it still does not reset, there might be a persistent fault or internal damage. Do not force the handle. Contact a qualified electrician.

7.3 No Power to Circuit

• Check if the circuit breaker is in the 'ON' position.
