Chint NXBLE32-4PC25 residual current operated circuit breaker​

Chint NXBLE32-4PC25 is a **4-pole residual current operated circuit breaker** belonging to the NXBLE series, mainly used for overload, short-circuit and leakage protection of circuits. The following is a detailed analysis based on search resources:

 I. Core Parameters and Functions

1. **Technical Specifications**  

   - **Poles and Current**: 4-pole design, rated current 25A, tripping characteristic is Type C (suitable for conventional lighting and resistive loads).  

   - **Breaking Capacity**: 6kA, which can quickly cut off short-circuit current to protect circuit safety.  

   - **Leakage Protection**: Residual operating current 30mA, in line with GB/T 16917.1 and IEC 61009-1 standards, can trigger tripping within 0.1 seconds to prevent electric shock risks.  

   - **Rated Voltage**: AC230V (single-pole) or AC400V (multi-pole), frequency 50Hz, suitable for residential, commercial and other scenarios.

2. **Structure and Certification**  

   - Adopts **DIN rail mounting**, with a compact size (width about 99mm), easy to integrate in distribution boxes.  

   - Has obtained **CCC certification**, some models have passed CE certification, but UL certification is not clearly mentioned. If used in the North American market, it is necessary to confirm whether it meets local standards (such as UL 943 or CSA C22.2 No. 14).

 II. Application Scenarios and Installation

1. **Typical Applications**  

   - Suitable for **three-phase four-wire circuits**, such as commercial buildings, small industrial equipment or residential main distribution boxes, which can protect phase lines and neutral lines at the same time.  

   - Especially suitable for places requiring leakage protection, such as kitchens, bathrooms and other humid environments.

2. **Installation Precautions**  

   - Wiring must be strictly in accordance with the instructions to ensure that phase lines and neutral lines are correctly connected to corresponding terminals.  

   - It is recommended to be operated by professional electricians. After installation, a leakage test should be carried out (press the test button, and the circuit breaker should disconnect immediately).  

   - If used in North America, attention should be paid to voltage matching (the US standard is 120/240V), there may be compatibility issues, so it is recommended to consult manufacturers or electricians.

 III. Market and Purchase

1. **Price and Channels**  

   - Users in the United States can purchase through cross-border e-commerce via Whatsapp: 0086-13811255435, but attention should be paid to import certification and logistics costs.  

   - It is recommended to give priority to officially authorized channels to avoid purchasing e-commerce exclusive versions (there may be differences in materials).

2. **Suggestions for Alternative Models**  

   - For higher reliability, Chint **NB1 series** or **Taiji series** can be considered, which have better craftsmanship and durability.  

   - North American users can pay attention to the **NXBLE American version models** launched by Chint for the local market (such as compatible with 60Hz frequency), but specific product manuals need to be checked.

 IV. User Feedback and Quality Tips

1. **User Experience**  

   - Most users report that installation is simple, operation feel is stable, and it is suitable for DIY scenarios.  

   - Some users point out that there are differences between products from e-commerce channels and physical channels, so it is recommended to purchase through official channels to ensure quality.

2. **Long-term Reliability**  

   - The mechanical life is about 20,000 times, and the electrical life is 10,000 times, which meets industry standards.  

   - The leakage function needs to be tested regularly (at least once a month), and check whether the terminal blocks are loose.

 V. Tips for Adaptability to the North American Market

1. **Certification and Standards**  

   - At present, search results do not clearly indicate that this model has passed UL certification. If used in the United States or Canada, it is necessary to confirm whether the product meets UL 943 or CSA standards, or choose Chint North American certified products (such as photovoltaic inverter series).  

   - The certification status can be checked by entering the model in the "Product iQ" system on the UL official website.

2. **Voltage and Frequency**  

   - The residential voltage in the United States is 120/240V (single-phase) or 208/240V (three-phase), while the AC400V rated voltage of NXBLE32-4PC25 may be incompatible, so careful evaluation is required.  

   - If used in North America, it is recommended to choose products designed by Chint for the local market (such as compatible with 60Hz frequency), or consult a professional electrician for system matching.

3. **After-sales Support**  

   - Chint provides a 1-3 year warranty, and the specific details are subject to the description of the purchase channel. In case of failure, repair or replacement can be applied for through official customer service.

 Summary

NXBLE32-4PC25 is a cost-effective leakage protection circuit breaker, suitable for domestic conventional circuit protection needs. For North American users, special attention should be paid to certification, voltage and frequency compatibility issues. It is recommended to give priority to localized products or consult professional electricians. When purchasing, be sure to go through formal channels to ensure product quality and after-sales guarantee.
