친트 NXBLE63 – 2PC40

친트 NXBLE63 – 2P/C40은 2 – 폴 (2피) 소형 잔류 전류 차단기. 주요 매개변수 및 기능은 다음과 같습니다.:

핵심 매개변수

정격전류: 40에이 (“Q40” 트립 특성이 Type C이고 정격 전류가 40A임을 나타냅니다.);

극수: 2피 (활선과 중성선을 동시에 차단합니다.);

잔류 전류 보호: 교류형 (detects ordinary AC leakage). The residual operating current is usually 30mA (an industry conventional value, and some models support options such as 50mA/75mA);

차단 용량: 6그만큼 (can safely cut off circuits with a short – circuit current of not less than 6000A);

적용 전압: 230다섯 (for single – 위상 회로);

Mechanical/Electrical Life: 기계적 수명은 20,000 타임스, 그리고 전기적 수명은 10,000 타임스.

주요 기능

1. 잔류 전류 보호: When there is electric shock to the human body (current ≥ 30mA) or equipment leakage in the circuit, the power supply is quickly cut off within 0.1 second to prevent electric shock casualties;
2. 과부하 보호: If the circuit load is too large (current exceeds 40A), it will automatically disconnect to avoid overheating and fire of the circuit;
3. 짧은 – 회로 보호: 회로에 단락이 발생한 경우 (current increases sharply in an instant), the circuit is cut off immediately to protect electrical appliances and the circuit;
4. 절연 기능: It can be used as a switch for infrequent on – off of the circuit under normal conditions.

응용 시나리오

가정용 전기: For high – power socket circuits in kitchens, 거실, 등. (에어컨과 같은, 전기 온수기), it replaces traditional air switches and adds residual current protection;

작은 – scale Commercial Places: For socket or lighting circuits in convenience stores and offices, meeting the electricity demand within 40A;

Decoration and Renovation: Upgrading the residual current protection of old circuits to meet the new national standard’s requirement that “socket circuits must be equipped with residual current protection”.

Installation and Use Precautions

– It should be selected according to the actual load of the circuit to avoid “a big horse pulling a small cart” 또는 “작은 말이 큰 수레를 끌고 있다”;

– 다음을 누르세요. “테스트 버튼 (T key)” once a month to verify whether the residual current protection function is normal;

– 설치시, the live wire (엘) 그리고 중성선 (N) must be distinguished. If the wiring is reversed, the residual current protection function may fail.
