친트 NXBLE-63YH-C20 RCOCB

CHINT NXBLE-63YH-C20 is a residual current operated 회로 차단기 (누전 차단기), belonging to the NXBLE series. It is mainly designed for overload, short-circuit and earth leakage protection in low-voltage distribution lines, and suitable for various scenarios such as industrial and civil applications.

Model Parameter Interpretation

핵심 기술 매개변수 (Default Standard Configuration, Subject to Nameplate for Specific Details)

1. 정격전압: Single-phase 230V AC, three-phase 400V AC (commonly used in single-phase scenarios)
2. 정격 주파수: 50Hz/60Hz
3. Residual Current Operation Parameters:

Rated residual operating current (IΔn): commonly 30mA (standard safety value for household/industrial use, which can cut off the power supply quickly to prevent electric shock); 10mA/300mA is available for customization in some models

Operating time: ≤0.1s (instantaneous protection against short-circuit/earth leakage); the operating time of arc fault protection complies with national standard requirements

4. 차단 용량: High breaking capacity (Class E), usually 6kA/10kA (may vary by batch, please check the nameplate), capable of withstanding high current impact during line short-circuit
5. Tripping Type: C형 트리핑, suitable for conventional loads to avoid non-fault tripping
6. 장착 방법: DIN 레일 장착 (compliant with DIN rail standard, 35mm rail, facilitating batch installation in distribution cabinets)
7. 극수: Commonly 1P+N, 2피 (please check the specific model; C20 specification is mostly 1P+N/2P, suitable for single-phase 220V lines)

응용 시나리오

Lighting and socket circuits in civil buildings such as residences, office buildings and shopping malls, providing dual protection against electric shock and electrical fire (arc fault + earth leakage)

Small power equipment and control circuits in industrial plants, protecting equipment and the safety of operators

Places sensitive to arc faults (such as old lines and lines around flammable materials); the AFDD function can effectively reduce the risk of fire caused by arcs

Alternative Reference of Corresponding Schneider Model (Selection with the Same Function)

For brand replacement, you can refer to Schneider iDPNa Vigi+ AFDD series, such as iDPNa Vigi+ AFDD C20 30mA. The core parameters are matched: 20A rated current, C형 트리핑, 30mA earth leakage protection, arc fault protection. The mounting method and breaking capacity are similar, allowing direct replacement (please check if the pole number, voltage and mounting dimensions are consistent).

설치 및 사용상의 주의사항

1. 설치 전, confirm that the line voltage and current match the parameters of the circuit breaker to avoid faults caused by overload or undervoltage
2. Wiring must be done according to the marks on the terminals (L for live wire, N for neutral wire, PE for protective earth wire); reverse connection is strictly prohibited for 1P+N models
3. 정기 테스트: 다음을 누르세요. “시험” button of the circuit breaker once a month to check whether the earth leakage/arc protection function is normal
4. Avoid use in humid, dusty and corrosive environments, which may affect the service life and operation reliability of the circuit breaker
5. Cut off the upper-level power supply before replacement; 실시간 작업은 엄격히 금지됩니다.

Parameter Comparison Table Between CHINT NXBLE-63YH-C20 and Corresponding Schneider Model

To facilitate your direct procurement and replacement, the following is a complete parameter comparison between CHINT NXBLE-63YH-C20 (1P+N/2P) and Schneider iC65N Vigi+ C20 (1P+N model: A9D65140; 2P model: A9D65240), covering core technical indicators and application compatibility.

Key Precautions for Replacement

1. Pole Number Matching: Confirm whether the original circuit is 1P+N or 2P, and select the corresponding Schneider model with the same pole number
2. 누설 유형: Schneider adopts Type A earth leakage protection (compatible with Type AC), while CHINT uses Type AC. Type A has a wider application range, and replacement is risk-free
3. Wiring Distinction: 1P+N 모델의 경우, strictly distinguish between neutral wire (N) 그리고 활선 (엘); 역접속 금지
4. 설치공간: The two models have the same width dimension and can directly replace the original installation position

Procurement Suggestions

For cost optimization: Choose CHINT NXBLE-63YH-C20 with higher cost performance

For brand consistency: Choose Schneider iC65N Vigi+ C20 with better compatibility with Schneider systems

For inventory replacement: The two models can be directly interchanged without modifying the circuit design or wiring method
