• 트립된 위치: 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.
• 트립된 차단기 재설정:
  1. 먼저, 트립의 원인을 파악하고 해결하세요(예: 과부하된 기기의 플러그를 뽑거나, 단락 회로를 수리하세요).
  2. 토글 스위치를 "OFF" 위치로 단단히 누르십시오.
  3. Then, push the toggle switch to the "ON" position to restore power.

  • 초과 적재: 회로에 과도한 전류가 흐르고 있을 수 있습니다. 회로에서 일부 장치를 분리하십시오.
  • 단락: A direct connection between live and neutral/ground wires. This requires immediate investigation by an electrician.
  • 결함이 있는 가전제품: An appliance connected to the circuit may be defective. Try isolating appliances to identify the culprit.
• 차단기가 재설정되지 않습니다:
  • Ensure the cause of the trip has been resolved.
  • 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.
• 회로에 전원이 공급되지 않음(차단기 켜짐):
  • 배전반의 다른 차단기가 트립되었는지 확인하십시오.
  • Verify main power supply to the panel.
  • Inspect wiring connections for looseness or damage (with power off).
