Chint NXBLE32-2PC25 is a قاطع الدائرة المصغرة with residual current protection function, suitable for circuit protection in residential, commercial and industrial scenarios. The following is a detailed analysis of its core parameters and characteristics:
أنا. المعلمات الأساسية
1. المواصفات الأساسية
– **Rated Current**: 25أ, applicable to circuits with a load current not exceeding 25A (مثل مكيفات الهواء, kitchen appliances, إلخ.).
– **Pole Number**: 2ص (two poles), which can cut off both the live wire and neutral wire simultaneously, providing more comprehensive safety protection.
– **Breaking Capacity**: 6ال, capable of quickly cutting off fault currents up to 6000A in case of short circuits, complying with the standards of GB/T 16917.1 واللجنة الانتخابية المستقلة 61009-1.
2. Residual Current Protection Function
– **Residual Operating Current**: 50أماه (confirmed based on the model suffix “2PC25” and search results). When the residual current reaches 50mA, the circuit breaker trips within 0.1 ثواني, effectively preventing electric shocks and electrical fires.
– **Tripping Characteristic**: منحنى النوع C, suitable for general loads such as lighting and sockets (the tripping current is 5-10 أضعاف التيار المقنن, أي., 125-250أ).
3. المعلمات الكهربائية
– **Rated Voltage**: 230V (for 2P model), applicable to single-phase 220V circuits.
– **Frequency**: 50هرتز, conforming to China’s power grid standards.
الثاني. Design and Safety Features
1. التصميم الهيكلي
– **Compact Size**: With a width of approximately 36mm (2 الوحدات النمطية), it can be installed on a standard 35mm guide rail, توفير مساحة في صندوق التوزيع.
– **Operation Indication**: A red mark shows “على” when the breaker is closed, and a green mark shows “OFF” when it is open, مما يجعل الحالة واضحة في لمحة. There is a test button on the side; it is recommended to press it once a month to check if the residual current protection function is normal.
2. Certification and Reliability
– It has passed the CCC certification and meets China’s mandatory safety standards; some models support CE certification, making them suitable for the international market.
– **Mechanical Life**: أكثر من 20,000 مرات; **Electrical Life**: أكثر من 10,000 مرات, featuring strong durability.
3. التركيب والصيانة
– **Wiring Method**: Top-in and bottom-out, supporting 6-10mm² wire connection. Attention should be paid to the correct connection of the neutral wire and live wire (L for live wire, N for neutral wire).
– **Removal Method**: The circuit breaker can be quickly removed through the “Lift” و “Tilt” operations on the side, facilitating maintenance or replacement.
ثالثا. سيناريوهات التطبيق
1. Residential Electricity Use
It serves as branch circuit protection, used in socket and lighting circuits in areas such as bedrooms, living rooms, and kitchens to prevent overload, ماس كهربائى, and residual current risks.
2. Commercial Premises
Suitable for small and medium-sized power distribution systems in offices, stores, إلخ., to protect the safety of equipment such as computers and printers.
3. التحكم الصناعي
It provides basic circuit protection in small industrial equipment or distribution boxes.
رابعا. اقتراحات الأسعار والشراء
1. سعر السوق
واتس اب: 0086-13811255435. The price per unit is approximately 24.53-45 يوان.
. Purchase Notes
– Confirm that the load current does not exceed 25A to avoid frequent tripping.
– If higher sensitivity (على سبيل المثال, 30أماه) مطلوب, you can choose the version with the suffix “30أماه” (such as NXBLE32-2PC25 30mA).
– It is recommended to purchase from official channels or authorized distributors to ensure product quality and after-sales service.
V. Usage and Maintenance Tips
1. Regular Testing
Press the test button monthly to observe whether it trips normally and ensure the residual current protection function is effective.
2. Fault Handling
After tripping, it is necessary to first eliminate line faults (such as short circuits, residual current), then press the reset button (blue button) before closing the breaker.
3. المتطلبات البيئية
Avoid using it in environments with high temperature, humidity, or heavy dust. It is recommended to install it in a distribution box to extend its service life.
With the above parameters and characteristics, Chint NXBLE32-2PC25 can provide reliable overload, short-circuit, and residual current protection for circuits, and is an ideal choice for residential and small-to-medium-sized power distribution systems. قبل التثبيت, be sure to refer to the product manual or consult a professional electrician to ensure correct model selection and wiring.
