친트 RCCB NBHLE-40Y-1PC32

CHINT NBHLE-40Y-1PC32 is a 1P+N two-pole 잔류 전류 차단기 (RCCB) specially designed for household and small-to-medium engineering applications. It integrates overload, 단락, 및 누출 방지 기능, suitable for AC 50Hz/60Hz circuits with a rated voltage of 230V. Below is its core information and application guidelines:

1. 핵심 기술 매개변수
2. 정격 전류 및 트립 특성

정격전류: 32에이, suitable for conventional loads such as lighting, 소켓, and small air conditioners, supporting up to approximately 7kW single-phase devices (예를 들어, instantaneous water heaters).

Default Type C trip characteristic (instantaneous trip at 5-10 times rated current), ideal for resistive loads (예를 들어, lamps, electric heaters); for inductive loads like motors, D형 (instantaneous trip at 10-14 times) is available.

2. Leakage Protection and Breaking Capacity

30mA leakage action current, rapidly cutting off faulty circuits within 0.1 초, compliant with IEC 61009-1 and GB/T 16917.1 standards to prevent electric shock and fire risks.

차단 용량: 6그만큼, capable of handling common household short-circuit currents (typically 2-4kA) to ensure safe power disconnection.

3. Electrical Performance and Certifications

– 정격전압: 230다섯, operating temperature range: -5°C ~ +70°C, IP20 protection grade, resistant to moisture and dust.

– Certified by CCC and compliant with CE standards, ensuring reliable quality.

1. 일반적인 애플리케이션 시나리오
2. Household Power Distribution Systems

Branch Circuit Protection: Socket circuits in humid areas like kitchens and bathrooms to prevent safety accidents from leakage. 예를 들어, 전기 온수기 (3-8kW) can directly use a 32A circuit breaker with 30mA leakage protection for dual-layer safety.

Whole-House Leakage Protection: If the distribution box lacks a main RCCB, NBHLE-40Y-1PC32 can serve as the main switch to monitor leakage across all circuits.

2. Commercial and Light Industrial Use

Small Office Equipment: Centralized power supply circuits for printers, 프로젝터, 물 디스펜서, 등., to avoid overload and leakage risks.

Store Lighting Systems: LED strips and display cabinet circuits in clothing stores, cafes, 등., providing stable protection.

3. New Energy Equipment Adaptation

AC Charging Pile Protection: 7kW 충전 파일 (32에이) can directly use this circuit breaker as the main switch, paired with NXB series circuit breakers for hierarchical control.

PV Inverter Branch: Protection for the AC side of small household PV systems to prevent damage from backflow current.

III. Installation and Selection Recommendations

1. 설치사양

Rail Mounting: Compatible with TH35-7.5mm standard rails, wiring terminals support 2.5-10mm² conductors, and vertical installation is required for optimal heat dissipation.

환경 요구 사항: Avoid installation in high-temperature (>70°C), high-humidity, or flammable environments; distribution boxes must have reserved heat dissipation space (벽에서 ≥30cm).

2. 선택 논리

부하 매칭: Equipment total power (여) ¼ 전압 (230다섯) = 현재 (에이). 회로 차단기의 정격 전류는 계산된 값의 1.2배 이상이어야 합니다.. 예를 들어, a 6kW load corresponds to 26.1A, making a 32A circuit breaker compliant.

Leakage Protection Hierarchy: If the main switch already has an RCCB, use ordinary circuit breakers (예를 들어, NXB63-2P/32A) for branches; if not, prioritize NBHLE series for whole-house protection.

3. Accessory Expansion

보조 기능: Can be paired with AX-X1 auxiliary contacts (indicate on/off status), AL-X1 alarm contacts (trigger signals during faults), or shunt trip coils (remote tripping control).

System Compatibility: Compatible with NXB series circuit breakers, rail sockets, and surge protectors (예를 들어, NXU) to build modular power distribution systems.

1. Maintenance and Safety Tips
2. Regular Inspections

Monthly Testing: Press the test button (TEST) to verify the leakage protection function. Replace immediately if it fails to trip.

Annual Check: Use an infrared thermometer to detect contact temperatures (≤60°C) 산화로 인한 접촉 저항 증가를 방지합니다..

2. Fault Troubleshooting

Frequent Tripping: If overload or short circuit is ruled out, aging insulation may be the cause, requiring professional electrical inspection.

Leakage Indicator Protrusion: Indicates a past leakage fault; identify and fix the cause before resetting.

1. 가격 및 구매 채널

Market Price: Reference price per unit is approximately 150-200 CNY (subject to local dealers).

Purchase Advice: Procure through CHINT’s official channels (예를 들어, Tmall flagship store, authorized dealers) to ensure product quality and after-sales service.
