5. אַפּערייטינג ינסטרוקטיאָנס
The NENEN NSX630 N TMD 630A Circuit Breaker is designed for straightforward operation.
Turning On the Circuit Breaker:
- Ensure all downstream loads are in a safe state (e.g., turned off or disconnected if necessary).
- Move the operating handle to the "ON" position. The handle should latch firmly in place.
- Restore power to the main circuit.
Turning Off the Circuit Breaker:
- Move the operating handle to the "OFF" position.
- Verify that power to the protected circuit is disconnected before performing any work.
Resetting a Tripped Circuit Breaker:
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).
- Identify and Rectify Fault: Determine the cause of the trip (e.g., overloaded circuit, short circuit) and correct the issue.
- 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.
- 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. וישאַלט
Regular maintenance helps ensure the longevity and reliable operation of your NENEN circuit breaker. Always disconnect power before performing any maintenance.
- וויזועלע דורכקוק (יערליך):
- 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.
