The Legrand DNX 4500 Circuit Breaker operates as a protective device for your electrical circuits.

• EIN-Stellung: To energize the circuit, push the toggle switch to the "ON" position (typically upwards).
• AUS-Position: To de-energize the circuit, push the toggle switch to the "OFF" position (typically downwards).
• Ausgelöste Position: If an overcurrent or short circuit occurs, the circuit breaker will automatically trip to an intermediate position (often center or fully down, depending on the model) to protect the circuit.
• Zurücksetzen eines ausgelösten Schutzschalters:
  1. Zuerst muss die Ursache der Auslösung ermittelt und behoben werden (z. B. überlastete Geräte ausstecken, Kurzschlüsse beheben).
  2. Push the toggle switch firmly to the "OFF" position.
  3. Then, push the toggle switch to the "ON" position to restore power.
  4. If the breaker trips immediately again, do not attempt to reset it repeatedly. Consult a qualified electrician.

7. Fehlerbehebung

If you encounter issues with your Legrand DNX 4500 Circuit Breaker, consider the following common scenarios:

• Häufige Auslösungen der Schutzschalter:
  • Überlast: The circuit may be drawing too much current. Unplug some devices from the circuit.
  • Kurzschluss: A direct connection between live and neutral/ground wires. This requires immediate investigation by an electrician.
  • Defektes Gerät: An appliance connected to the circuit may be defective. Try isolating appliances to identify the culprit.
• Sicherung wird nicht zurückgesetzt:
  • Stellen Sie sicher, dass die Ursache der Reise behoben wurde.
  • Push the switch firmly to the "OFF" position before attempting to reset to "ON".
  • If it still doesn't reset, the breaker itself might be faulty, or there's a persistent fault in the circuit. Do not force it; consult an electrician.
• Keine Stromversorgung (Leistungsschalter EIN):
  • Check if other breakers in the panel are tripped.
  • Verify main power supply to the panel.
  • Inspect wiring connections for looseness or damage (with power off).
