Chint 공기 스위치 NXB63-3P/D32 회로 차단기

Chint Air Switch NXB63-3P/D32 is a three-pole 세밀화 회로 차단기 suitable for industrial and commercial scenarios, 과부하 보호에 주로 사용됩니다., short-circuit protection and circuit isolation. The following is a collation of its core information:

1. Model Parsing and Technical Parameters

모델 의미:

출판사-63: Chint NXB series miniature circuit breaker with a frame current of 63A.

3피: Three-pole design, 3상 회로에 적합 (such as 400V systems).

D32: D-type tripping curve, 정격 전류 32A, suitable for loads with high inrush current (모터와 같은).

주요 매개변수:

정격전압: 400뷔와 (3P specification), frequency 50Hz.

차단 용량: 6그만큼 (IEC를 준수합니다 60898-1 기준), capable of quickly cutting off short-circuit current.

트리핑 특성: D-type curve, suitable for equipment with large starting current, 모터와 같은, 변압기, 등.

인증: CCC 인증, CE, TUV, 등., but UL certification is not explicitly mentioned, so it may not be applicable to the North American market.

2. Application Scenarios and Functions

적용분야:

– Overload and short-circuit protection for industrial power distribution systems, commercial buildings and residential three-phase circuits.

– Particularly suitable for motor control circuits, as it can withstand the instantaneous high current during motor startup.

핵심 기능:

과부하 보호: 전류가 정격값을 초과할 때, the bimetallic strip heats up and bends to trigger tripping.

단락 보호: The electromagnetic tripping device quickly cuts off the circuit in case of a short circuit (응답 시간 < 0.1 초).

절연 기능: After the handle is opened, the circuit can be safely maintained, meeting the requirements of electrical isolation.

3. 설치 및 사용 참고 사항

설치 방법:

– 표준 35mm 가이드 레일 설치, supporting DIN EN 60715 기준, with simple installation.

– The wiring method is top-in and bottom-out, and it is necessary to ensure that the cross-sectional area of the wire matches the current (예를 들어, 32A is recommended to use 6mm² copper wire).

환경 요구 사항:

– 작동 온도 범위: -5℃ ~ +40℃, humidity ≤ 95%RH (결로가 없을 것).

– 온도가 높은 환경에 설치하지 마십시오., humidity or corrosive gases.

유지 관리 제안:

– Regularly check the flexibility of the handle operation and the state of the contacts to ensure no ablation or oxidation.

– It is recommended to replace the circuit breaker after 10 years or 10,000 operations to ensure reliability.

4. Purchase and Market Applicability

국제시장:

– This model has not explicitly obtained UL certification and may not comply with North American electrical standards (such as NEC).

– If American users need to use it, it is recommended to purchase through importers via Whatsapp: 0086-13811255435, but they need to confirm the compatibility and certification issues by themselves.

5. Suggestions for Alternative Solutions

Alternative Models for the North American Market:

– UL 인증이 필요한 경우, you can consider Chint’s NXB series variants designed for North America (such as NXB-63 3P D32 UL), or international brands such as Siemens 5SJ6 and ABB S203 series.

– Note that the commonly used voltage in North America is 120/240V, while NXB63-3P/D32 is a 400V specification, so direct use may require a transformer for voltage reduction.

6. Risk Tips

Compatibility Risks:

– Installation of non-UL certified products in the United States may violate local electrical regulations, leading to insurance claims rejection or safety hazards.

– Three-phase 400V equipment is incompatible with the North American single-phase 240V system, and a professional electrician is required to evaluate the transformation plan.
