4. 설정 및 설치

The THQB32050 circuit breaker is designed for bolt-on installation into compatible electrical panels. Ensure the panel is de-energized before beginning installation.

설치 단계:

1. 전원 차단 패널: Turn off the main power supply to the electrical panel at the utility meter or main disconnect. Verify with a voltage tester that all circuits are de-energized.
2. 장착 위치 식별: Select an appropriate slot in the electrical panel for the 3-pole breaker.
3. 포지션 브레이커: Align the bolt-on terminals of the THQB32050 with the corresponding bus bar connections in the panel.
4. 보안 차단기: Fasten the breaker securely to the bus bar using the integrated bolt-on mechanism. Ensure a tight and reliable connection.
5. 와이어 연결: Connect the load wires to the appropriate terminals on the circuit breaker. Ensure all connections are tight and properly insulated. Refer to local electrical codes for wire sizing and torque specifications.
6. 설치 확인: Double-check all connections and ensure the breaker is firmly seated.
7. 패널 재충전: 배전반에 전원을 복구하십시오.

5. 사용 설명서

The ABB THQB32050 circuit breaker operates with a simple ON/OFF mechanism and provides clear trip indication.

작업:

• 켜려면: Push the handle firmly to the 'ON' position.
• 끄려면: Push the handle firmly to the 'OFF' position.
• 여행 표시: If an overcurrent or short circuit occurs, the breaker will automatically trip. The handle will move to a central, 'TRIPPED' position, which is typically between 'ON' and 'OFF'.
• 트립된 차단기 재설정: To reset a tripped breaker, first move the handle completely to the 'OFF' position, then push it firmly to the 'ON' position. Investigate the cause of the trip before resetting.

6. 유지관리

The ABB THQB32050 circuit breaker is designed for minimal maintenance. Regular visual inspections are recommended to ensure optimal performance and safety.

권장 유지 관리:

• 시각적 검사: 차단기에 물리적 손상, 변색 또는 느슨한 연결 흔적이 있는지 주기적으로 검사하세요.
• 청결: Ensure the area around the circuit breaker is free from dust, debris, and moisture.
• 연결 확인: During scheduled electrical system maintenance, verify that all bolt-on connections remain tight.
• 테스트: Do not attempt to test the tripping mechanism by intentionally creating a short circuit. This can be dangerous and damage the electrical system.

7. 문제 해결

If the circuit breaker trips frequently or fails to operate correctly, consider the following troubleshooting steps:

• 자주 트리핑: This often indicates an overload or a short circuit on the protected circuit. Disconnect appliances or devices from the circuit and try resetting the breaker. If it continues to trip, consult a qualified electrician to identify and resolve the underlying electrical issue.
• 차단기가 재설정되지 않습니다: Ensure the handle is moved fully to the 'OFF' position before attempting to move it to 'ON'. If it still does not reset, there may be a persistent fault on the circuit or the breaker itself may be faulty. Do not force the handle.
• 회로에 전원이 공급되지 않음: Check if the breaker is in the 'ON' position. If it is, and there's still no power, verify connections or consult an electrician.
• 눈에 보이는 손상: If the breaker shows signs of burning, melting, or other physical damage, it must be replaced immediately by a qualified electrician.
