ABB S203-C32 회로 차단기 사용자 설명서

1. 서론

The ABB S203-C32 is a three-pole miniature circuit breaker (MCB) designed for reliable protection of electrical circuits against overloads and short circuits. This device is part of the S200 series, engineered for easy installation and robust performance in various applications, including residential and commercial buildings.

It features a C-characteristic activation, meaning it trips when the overcurrent is 5 to 10 times the nominal current, making it suitable for circuits with moderate inrush currents. With a nominal current of 32 Amperes and a rated breaking capacity of 6 kA according to EN 60898-1, the S203-C32 provides essential safety for three-phase electrical systems.

2. 안전 정보

경고: 전기 작업은 자격을 갖추고 허가받은 사람만 수행해야 합니다. 이 지침을 따르지 않을 경우 심각한 부상이나 사망에 이를 수 있습니다.

• Always disconnect power at the main supply before installing, servicing, or removing the circuit breaker.
• 볼륨을 확인하세요tag차단기의 정격 전류 및 전류 용량이 전기 시스템의 요구 사항과 일치하는지 확인하십시오.
• 현지 전기 규정 및 규정에 따라 적절한 접지 및 배선을 확보하세요.
• 회로 차단기가 손상된 것으로 보이거나 과도한 힘이 가해진 경우 회로 차단기를 작동하지 마십시오.
• Wear appropriate personal protective equipment (PPE), such as insulated gloves and safety glasses, when working with electrical systems.

3. 설치

The ABB S203-C32 circuit breaker is designed for easy installation on standard DIN rails. Its patented twin terminals with spring-loaded screws facilitate secure connection of conductors.

3.1 DIN 레일 장착

1. Ensure the main power supply to the distribution board is switched off and locked out.
2. 회로 차단기를 DIN 레일에 맞춰 설치하십시오.
3. Press the circuit breaker firmly onto the DIN rail until it clicks into place. Ensure it is securely seated.

3.2 배선 연결

The S203-C32 features three poles for three-phase circuit protection. It is equipped with twin terminals that allow for secure wiring.

1. Strip the insulation from the conductor ends to the recommended length (typically 12-14 mm).
2. Insert the conductors into the appropriate terminals (input and output). The terminals are designed to accept conductors up to 35 mm² cross-section.
3. Tighten the terminal screws to the specified torque (refer to product markings or technical data sheet for exact torque values, typically 2.8 Nm). Ensure connections are firm to prevent loose contacts and overheating.
4. Verify all connections are secure and that no bare wires are exposed, ensuring touch protection according to IP20.

4. 운영

The ABB S203-C32 circuit breaker operates automatically to protect electrical circuits. It has two primary states: ON and OFF, and an automatic trip state.

• ON 위치: When the toggle switch is in the upward position, the circuit is closed, allowing current to flow.
• 꺼짐 위치: When the toggle switch is in the downward position, the circuit is open, interrupting current flow. This position is used for manual disconnection.
• 트립된 위치: In the event of an overload or short circuit, the circuit breaker will automatically trip, moving the toggle switch to an intermediate or fully down position (depending on the specific mechanism). This indicates a fault in the circuit.

To reset a tripped circuit breaker, first identify and rectify the cause of the trip (e.g., remove overloaded devices or fix short circuits). Then, firmly push the toggle switch all the way down to the OFF position, and then back up to the ON position.

5. 유지관리

The ABB S203-C32 circuit breaker is designed for maintenance-free operation under normal conditions. However, periodic inspection is recommended to ensure continued reliability and safety.

• 시각적 검사: Regularly inspect the circuit breaker for any signs of physical damage, discoloration, or loose connections. Ensure the toggle switch moves freely.
• 청소: 필요한 경우, 보풀이 없는 마른 천으로 회로 차단기 외부를 부드럽게 닦으십시오. 연마성 세제나 용제를 사용하지 마십시오. 청소하기 전에 전원이 차단되었는지 확인하십시오.
• 연결 확인: Periodically check the tightness of the terminal screws, especially after initial installation and during routine electrical system checks.

If any damage or malfunction is observed, the circuit breaker should be replaced by a qualified electrician.

6. 문제 해결

This section provides guidance for common issues encountered with circuit breakers.

6.1 Circuit Breaker Trips Frequently

• 초과 적재: The most common cause. Disconnect some appliances or devices from the circuit.
• 단락: A direct connection between live and neutral/ground wires. This requires immediate attention from a qualified electrician to identify and repair the fault.
• 결함이 있는 가전제품: An appliance connected to the circuit may be faulty and drawing excessive current. Unplug all appliances and plug them back in one by one to identify the culprit.
• 느슨한 연결: Loose wiring connections can cause arcing and heat, leading to tripping. Have a qualified electrician inspect and tighten all connections.

6.2 Circuit Breaker Will Not Reset

• 지속적인 오류: If the underlying overload or short circuit condition still exists, the breaker will immediately trip again when you try to reset it. Do not force it.
• 내부 손상: The circuit breaker itself may be damaged internally. If no fault is found in the circuit and the breaker still won't reset, it likely needs replacement.

If you are unable to resolve the issue, contact a qualified electrician for assistance.
