If an overload or short circuit occurs, the circuit breaker will automatically trip to the "TRIPPED" position (often indicated by an intermediate handle position or a visual indicator).

1. Identify and Rectify Fault: Determine the cause of the trip (e.g., overloaded circuit, short circuit) and correct the issue.
2. Reset Handle: Fully push the operating handle to the "OFF" position first, then move it to the "ON" position. This resets the internal tripping mechanism.
3. If the circuit breaker trips immediately again, do not attempt to reset it repeatedly. Consult a qualified electrician to diagnose the underlying electrical fault.

6. Antretyen

Regular maintenance helps ensure the longevity and reliable operation of your NENEN circuit breaker. Always disconnect power before performing any maintenance.

• Visual Inspection (Annually):
  • Check for any signs of physical damage, discoloration, or overheating on the circuit breaker body and terminals.
  • Ensure all terminal connections are tight. Retighten if necessary, adhering to specified torque values.
  • Clean any dust or debris from the circuit breaker's exterior using a dry, non-abrasive cloth.
• Functional Test (Periodically):
  • If equipped with a test button, press it to verify the tripping mechanism is functional. The breaker should trip.
  • Reset the breaker after testing.
• Do not attempt to open or repair the internal components of the circuit breaker. Refer all internal servicing to qualified personnel.
