Chint NXBLE32-2PC25 is a disjoncteur miniature 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:
je. Paramètres de base
1. Spécifications de base
– **Rated Current**: 25UN, applicable to circuits with a load current not exceeding 25A (comme les climatiseurs, kitchen appliances, etc.).
– **Pole Number**: 2P. (two poles), which can cut off both the live wire and neutral wire simultaneously, providing more comprehensive safety protection.
– **Breaking Capacity**: 6le, capable of quickly cutting off fault currents up to 6000A in case of short circuits, complying with the standards of GB/T 16917.1 et CEI 61009-1.
2. Residual Current Protection Function
– **Residual Operating Current**: 50mA (confirmed based on the model suffix “2PC25” and search results). When the residual current reaches 50mA, the circuit breaker trips within 0.1 secondes, effectively preventing electric shocks and electrical fires.
– **Tripping Characteristic**: Type C curve, suitable for general loads such as lighting and sockets (the tripping current is 5-10 fois le courant nominal, c'est-à-dire, 125-250UN).
3. Paramètres électriques
– **Rated Voltage**: 230V (for 2P model), applicable to single-phase 220V circuits.
– **Frequency**: 50HZ, conforming to China’s power grid standards.
Ii. Design and Safety Features
1. Conception structurelle
– **Compact Size**: With a width of approximately 36mm (2 modules), it can be installed on a standard 35mm guide rail, gain de place dans le coffret de distribution.
– **Operation Indication**: A red mark shows “ON” when the breaker is closed, and a green mark shows “OFF” when it is open, making the status clear at a glance. 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**: Plus que 20,000 fois; **Electrical Life**: Plus que 10,000 fois, doté d'une forte durabilité.
3. Installation et entretien
– **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” et “Tilt” operations on the side, facilitating maintenance or replacement.
III. Scénarios d'application
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, court-circuit, and residual current risks.
2. Commercial Premises
Suitable for small and medium-sized power distribution systems in offices, stores, etc., to protect the safety of equipment such as computers and printers.
3. Contrôle industriel
It provides basic circuit protection in small industrial equipment or distribution boxes.
IV. Price and Purchase Suggestions
1. Market Price
WhatsApp: 0086-13811255435. Le prix unitaire est d'environ 24.53-45 RMB.
. Purchase Notes
– Confirm that the load current does not exceed 25A to avoid frequent tripping.
– If higher sensitivity (par ex., 30mA) est requis, you can choose the version with the suffix “30mA” (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. Exigences environnementales
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. Avant l'installation, be sure to refer to the product manual or consult a professional electrician to ensure correct model selection and wiring.
