power distribution cabinet based on Chint components

If you need to customize a power distribution cabinet based on Chint components, the following is key information and a process description to help you efficiently advance the project:

I. Confirmation of Core Requirements

1. **Application Scenarios*molded case circuit breaker  Price*

    - Clearly define the usage environment of the power distribution cabinet (such as industrial automation, data centers, new energy power stations, buildings, etc.). Different scenarios have significant differences in requirements for protection levels (such as IP54/IP65), seismic resistance, corrosion resistance, etc. For example:

    - **Industrial Scenarios**: It needs to pass CE and UL certifications and support high-temperature environments (-25°C to +55°C).

    - **Outdoor Scenarios**: It is necessary to use aluminum alloy or 304 stainless steel cabinets, and the protection level reaches IP65.

2. **Functional Requirements*CHINT circuit breaker price*

    - List specific functional modules (such as motor control, reactive power compensation, intelligent monitoring, etc.) and provide the following parameters:

    - **Electrical Parameters**: Rated voltage (such as AC 380V/690V), current (such as 100A to 6300A), short-circuit withstand current (such as 50kA to 80kA).

    - **Protection Functions**: Overload, short-circuit, undervoltage, leakage protection, etc.

    - **Intelligent Requirements**: Support Modbus/Profibus communication, remote monitoring, power quality analysis, etc.

3. **Space Limitations*CHINT surge protector price*

    - Provide the dimensions of the installation location (such as width × depth × height: 800mm × 600mm × 2200mm). If it is a non-standard size, it needs to be stated in advance.

II. Suggestions for the Selection of Chint Components

III. Customization Process and Cycle

1. **Requirement Docking*Schneider Circuit Breakers price*

    - Provide a technical parameter table or drawings, and Chint's authorized distributors (such as Zhejiang Shenhua Explosion-proof Technology) will provide a preliminary plan within 1 to 3 working days.

    - Example: If you need to customize 10 power cabinets with NVF2G frequency converters, you need to clarify the cabinet material (cold-rolled steel plate/stainless steel), the incoming line method (bottom-in and bottom-out/top-in and top-out), etc.

2. **Design and ConfirmationSchneider LRD Thermal Relay Price*

    - The 2D layout (including component arrangement and wire duct routing) and 3D renderings will be completed within 5 to 7 working days and need to be signed and confirmed by the customer.

    - If it involves complex functions (such as multi-circuit control), it may take an additional 3 to 5 working days for PLC program development.

3. **Production and Testing**

    - The production cycle of standard cabinets is 15 to 20 working days, and non-standard cabinets (such as customized sizes) require 25 to 30 working days.

    - Before leaving the factory, conduct a withstand voltage test (AC 2500V/1 minute), a temperature rise test, and a functional joint debugging to ensure compliance with the IEC 61439 standard.

4. **Delivery and Installation**

    - Domestic transportation usually takes 3 to 5 days, and remote areas require 5 to 7 days.

    - On-site installation guidance can be provided, and the fee will be negotiated according to the project scale (about 1000 to 5000 yuan per set).

 IV. Factors Affecting the Price

**Example Quotations**:

- Basic power cabinet (NM1 circuit breaker + NC2 contactor): About 5000 yuan per unit.

- Intelligent power distribution cabinet (NDM3 frame circuit breaker + NVF2G frequency converter + communication module): About 25,000 yuan per unit.

V. After-sales Service

1. **Warranty Period**

    - The whole machine is under warranty for 2 years, and the core components (such as circuit breakers and contactors) are under warranty for 5 years.

2. **Technical Support**

    - The 7×24-hour hotline (Whatsapp: 0086-13811255435) provides fault troubleshooting guidance.  

3. **Upgrade Service**

    - Support the intelligent transformation of old cabinets (such as installing NDM3 intelligent circuit breakers), and the cost is about 30% to 50% of the price of a new cabinet.

 VI. Recommended Cooperation Channels

1. **Chint Authorized Distributor**  

(Whatsapp: 0086-13811255435)

VII. Precautions

1. **Compatibility Testing**

    - If the power distribution cabinet needs to be docked with third-party equipment (such as PLCs and upper computers), it is recommended to provide the communication protocol (such as Modbus RTU) in the design stage to avoid compatibility issues in the later stage.

2. **Environmental Assessment**

    - In high-altitude areas (>1000 meters), plateau-type components need to be selected, and in coastal areas, salt spray corrosion protection needs to be considered.

3. **Document Delivery**

    - Provide technical documents such as schematic diagrams, wiring diagrams, component lists, and test reports when leaving the factory. It is recommended that customers file them for maintenance.

Through the above steps, you can efficiently advance the customization project of Chint component power distribution cabinets. If you need further communication, please provide specific requirements (such as drawings and parameter tables), and we will assist in docking with Chint's official technical team or authorized distributors.

How is the price of a customized Chint component power distribution cabinet calculated?

The calculation of the price of a customized Chint component power distribution cabinet involves **five core dimensions**, and its pricing logic is deeply bound to the complexity of the industrial scenario. The following is a systematic analysis based on industry practices:
