- BL 유형: Specifically designed for Siemens panel boards.
- Double Pole: Provides protection for two electrical phases or a single 240-volt circuit.
- 125-Amp 평가: Suitable for circuits requiring up to 125 amperes of protection.
- 10KAIC 차단 등급: 최대 10,000Ω까지의 고장 전류를 안전하게 차단할 수 있습니다. Amp에레스.
- Bolt-On Mount: Ensures secure and stable connection within the panel board.
- UL 등재: 안전 및 성능 기준에 대한 인증을 받았습니다.
4. 설정 및 설치
Installation of the Siemens B2125 circuit breaker requires adherence to safety protocols and electrical codes. This is a general guide; consult a qualified electrician for specific installation requirements.
- 전원 차단: Turn off the main power supply to the electrical panel at the utility meter or main disconnect. Verify zero voltag적절한 테스트 장치를 사용하여.
- 패널 접근: 전기 패널 덮개를 조심스럽게 제거하여 버스 바와 배선 영역을 드러내십시오.
- 브레이커 배치: Identify an available space on the panel board's bus bar compatible with a bolt-on type BL breaker.
- 설치: Align the circuit breaker's bolt-on connectors with the bus bar terminals. Securely fasten the breaker to the bus bar using the provided bolts, ensuring a tight electrical connection.
- 배선: Connect the load wires to the appropriate terminals on the circuit breaker. For a double pole breaker, connect one phase wire to each terminal. Ensure the wires are stripped to the correct length and inserted fully into the terminals. Tighten the terminal screws to the torque specifications indicated on the breaker or in the panel documentation.
- 패널 커버: 모든 연결이 안전하고 검증되면 전기 패널 커버를 다시 장착합니다.
- 전원 복원: 메인 서비스 패널에 전원을 공급합니다.

5. 사용 설명서
The Siemens B2125 circuit breaker operates automatically to protect electrical circuits from overcurrents and short circuits. It has two primary states: ON and TRIPPED/OFF.
- ON 위치: When the handle is in the 'ON' position, power is supplied through the breaker to the connected circuit.
- 트립 위치: In the event of an overcurrent or short circuit, the breaker will automatically move to a 'TRIPPED' position (often midway between ON and OFF) to interrupt the power flow and protect the circuit.
- 트립된 차단기 재설정: To restore power after a trip, first move the handle fully to the 'OFF' position, then push it firmly to the 'ON' position. If the breaker immediately trips again, there is likely a persistent fault in the circuit that needs to be investigated by a qualified electrician.
6. 유지관리
Circuit breakers generally require minimal maintenance. However, periodic visual inspection is recommended.
- 시각적 검사: Annually, or as local codes require, have a qualified electrician inspect the circuit breaker and its connections for any signs of overheating, loose wires, or physical damage.
- 청소: Ensure the area around the breaker is free from dust and debris. Do not use liquids for cleaning inside the electrical panel.
- 테스트: Do not routinely test the trip mechanism by intentionally creating a fault. This can stress the breaker and connected equipment.

7. 문제 해결
If your Siemens B2125 circuit breaker is not functioning as expected, consider the following:
- 브레이커 트립이 자주 발생합니다. This indicates an overload or a short circuit in the connected wiring or appliances. Disconnect appliances from the circuit and try resetting the breaker. If it still trips, consult a qualified electrician to identify and resolve the underlying electrical fault.
- 차단기가 재설정되지 않습니다: If the breaker handle does not stay in the 'ON' position after being moved to 'OFF' and then 'ON', there is likely a persistent fault. Do not force the handle. Contact a qualified electrician.
- 회로에 전원이 공급되지 않음(차단기 켜짐): Ensure the main power supply to the panel is active. Check for loose connections at the breaker terminals (only by a qualified electrician with power off). If the issue persists, professional diagnosis is required.

9. 보증 정보
Siemens strongly recommends against the use of "used" breakers. The installation of used breakers in a Siemens panel will void the warranty on the panel. Siemens does not sell used breakers and has not approved any third-party sellers to do so. For specific warranty details, please refer to the official Siemens warranty documentation or contact Siemens customer support.
10. 지원 및 연락처
