4. Упутство за употребу

The thermal overload protector functions as an automatic circuit breaker. When an overcurrent condition occurs, the internal thermal element heats up and trips the breaker, disconnecting the circuit to prevent damage. The white button will pop out, indicating a tripped state.

1. Нормалан рад: Once installed and wired correctly, the protector allows current to flow through the circuit.
2. Заштита од преоптерећења: If the current exceeds the rated amperage (e.g., 10A, 15A, or 20A), the protector will automatically trip.
3. Resetting the Protector: After the protector trips, identify and resolve the cause of the overcurrent (e.g., remove the overloaded device, fix a short circuit). Allow a brief period for the thermal element to cool down. Then, firmly press the white reset button back in until it clicks into place. The circuit should now be re-energized.

CAUTION: Do not force the reset button if it does not stay in. Repeated tripping indicates a persistent problem that must be addressed.

5. Одржавање

The Fydun Thermal Overload Protector is constructed from durable plastic and metal components, designed for long service life with minimal maintenance.

• Редовна инспекција: Periodically inspect the protector for any signs of physical damage, discoloration, or loose connections.
• Чишћење: If necessary, gently wipe the exterior with a dry, clean cloth. Do not use abrasive cleaners or solvents.
• Провера везе: Ensure that all electrical connections remain tight and free from corrosion.

КСНУМКС. Решавање проблема

• Protector trips frequently:
  - The circuit may be consistently drawing more current than the protector's rating. Verify the load's current draw.
  - There might be a short circuit or ground fault in the system. Inspect wiring and connected devices.
  - The protector itself might be faulty. Consider replacement if other causes are ruled out.
• Protector does not reset:
  - The thermal element may still be too hot. Allow more time for cooling.
  - The underlying overcurrent condition may still be present. Ensure the fault is cleared.
  - The protector may be damaged internally. Replacement is necessary.
• No power to circuit after installation:
  - Check all wiring connections for correctness and tightness.
  - Ensure the protector's reset button is fully engaged.
  - Verify that power is supplied to the input side of the protector.
