Chint NB163H/1PC16 is a singlepole miniature circuit breaker with high breaking capacity. It is suitable for circuits with AC 50Hz and rated voltage of 230/400V, mainly providing overload and shortcircuit protection functions.
- 핵심 매개변수 및 기능
- 모델 의미
NB1: Series code for Chint miniature circuit breakers;
63: Frame rating current (the maximum current supported by this series is 63A);
H: High breaking capacity, with an ultimate shortcircuit breaking capacity of 10kA;
1피: Singlepole design, controlling only the live wire;
C16: Type C tripping curve, suitable for conventional loads (such as lighting and sockets), with an instantaneous tripping range of 510 정격 전류의 배 (즉., quick tripping occurs when the current is 80160A).
- Technical Characteristics
전기적 수명: 4000 운영 (for rated current ≤ 32A) 또는 2000 운영 (for 4063A), with a mechanical life of up to 20,000 운영;
Wiring Capacity: Supports a maximum 25mm² copper conductor, adopts screwcompressed terminals, and the torque should be controlled at 2.0Nm;
환경 적응성: Operating temperature range is 25°C to +60°C. No derating is required when the altitude is ≤ 2000m; when the altitude exceeds 2000m, the rated current is derated by 10% for every 1000m increase in altitude;
Certification Standards: Certified by CCC, CE, and SEMKO, complying with GB 10963.1 그리고 IEC 608981 표준.
- Function Expansion
It can be used in conjunction with modular accessories such as S9 auxiliary contacts, V9 alarm contacts, and XF9 shunt trip devices to realize functions like remote control and status indication.
- Application Scenarios and Selection Recommendations
- 일반적인 응용 분야
주거용 배전: Used as a protection switch for lighting circuits (예를 들어, LED lamp sets with 16A load) and sockets for small electrical appliances (예를 들어, televisions, 컴퓨터);
Commercial and Industrial Use: Suitable for controlling singlephase equipment below 3kW (예를 들어, small air conditioners, power tools) or as branch protection for distribution boxes.
- Selection Comparison
Comparison with Schneider iC65H: Both have a breaking capacity of 10kA, but the price of Chint NB163H is about 30% lower, offering better cost performance; Schneider has a richer accessory ecosystem, making it suitable for complex control requirements;
Comparison with Other Chint Series: NB163H is positioned higher than NB7 (a copy of DZ47), with stronger breaking capacity and reliability. It is close to the highend NB8 series but only costs half the price of the latter.
- 지침
Derated Use: In highaltitude areas, the rated current needs to be adjusted according to the actual altitude (예를 들어, the actual usable current of C16 is 14.4A at 2500m);
Matching Earth Leakage Protector: If earth leakage protection is required, it should be matched with the NB1LE63H series residual current circuit breakers (예를 들어, NB1LE63H 1P+N C16 30mA).
III. Installation and Usage
- 설치 방법
It adopts TH357.5mm standard guide rail installation. The width of the 1P circuit breaker is 18mm (1 기준 치수), which can be densely arranged in the distribution box.
