2. Application Scenarios and Load Matching

2.1 일반적인 응용 분야

주거용 배전: Used for protecting the circuits of high – power electrical appliances such as three – phase air conditioners and electric water heaters.

상업용 건물: Applied in the lighting systems of offices and shopping malls, as well as for small three – 위상 장비 (예를 들어, elevator control circuits).

산업 시나리오: Suitable for end – ~의 – line power distribution lines of automated production lines and small motors. 하지만, it should be noted that the Type C curve may not be suitable for high – inrush current loads (예를 들어, directly started motors).

2.2 Load Selection Recommendations

Loads Suitable for Type C Curve:

– Lighting fixtures (백열등, LED lamps, 등.).

– Ordinary sockets (for computers, 텔레비전, 소형 가전제품).

– Resistive loads (전기 히터, 물 디스펜서).

Scenarios to Avoid:

– 모터 (the starting current can reach 5 – 10 정격 전류의 배, which may cause false tripping).

– Inductive loads such as welding machines and compressors (a Type D curve is recommended).

3. Installation and Expansion Functions

3.1 설치 방법

레일 설치: It can be directly fixed on a standard 35mm DIN rail using the snap – fit on the back. It supports both top and bottom wire entry, with a wiring torque of 2.5N·m.

배선 용량: It can accommodate single – core hard wires (1 – 25mm²) or flexible wires (1 – 16mm²). The tunnel – type terminal design ensures a reliable connection.

3.2 액세서리 확장

Earth Leakage Protection: It can be assembled with a Vigi IC65 earth leakage module (예를 들어, Vigi C16A) to provide 30mA residual current protection. It is suitable for humid environments such as bathrooms and kitchens.

상태 모니터링:

OF Auxiliary Contact: Feeds back the on/off status of the circuit breaker through normally open/normally closed signals, and is used for remote monitoring or PLC systems.

SD Alarm Contact: Triggers an alarm when a fault trip occurs, facilitating quick location of the faulty circuit.

제어 기능:

MX Shunt Trip: Controls the circuit breaker to open remotely (예를 들어, for fire alarm linkage).

MN Undervoltage Trip: Automatically disconnects the circuit when the voltage is abnormal, 민감한 장비 보호.

4. 인증 및 규정 준수

국제 인증: IEC를 준수합니다. 60898 – 1 (Circuit Breakers for Household and Similar Purposes) 그리고 GB 10963.1 (중국 표준). It has obtained CCC and CE certifications, ensuring its applicability in the global market.

환경 적응성:

– 작동 온도: – 35°C ~ + 70℃, suitable for wide – temperature environments.

– Pollution Degree Resistance: 수업 3, enabling stable operation in general industrial environments.

5. 주요 선택 고려 사항

5.1 현재 매칭

– 정격 전류 (16에이) should be greater than the maximum continuous load current of the circuit. It is recommended to calculate based on the load power (예를 들어, for three – 위상 부하: Power = √3 × Voltage × Current × Power Factor).

– Avoid Overload: 예를 들어, the maximum resistive load that a 16A circuit breaker can handle is approximately 10.5kW (400V × 16A × 1.5).

5.2 Verification of Breaking Capacity

– Ensure that the prospective short – circuit current at the installation location does not exceed 6kA. If the short – circuit risk is high (예를 들어, near a transformer), a type with higher breaking capacity such as H – 유형 (10그만큼) or L – 유형 (15그만큼) 선택되어야 한다.

5.3 Earth Leakage Protection Requirements

– For locations sensitive to personal safety (예를 들어, residential bathrooms, 야외 장비), an earth leakage module (비기) should be used together, rather than relying solely on the overload/short – circuit protection of the circuit breaker itself.

6. Price and Market Reference

가격: A single – 극 회로 차단기 (1P C16A) costs approximately 30 – 50 원, and a three – pole model (3P C16A) ranges from 80 에게 120 원. The specific price varies depending on the purchasing channel and quantity.

비용 – Effectiveness Advantage: Compared with competing products, the IC65N series is renowned for its high reliability, 모듈식 디자인, and wide accessory compatibility. It is suitable for projects with high requirements for stability and expandability.
