CHINT-NBPLE-63-2P-63 Residual Current Circuit Breaker (RCCB)

Specific information about the **CHINT-NBPLE-63-2P-63 Residual Current Circuit Breaker (RCCB)**:

 I. Model Analysis and Parameter Confirmation

1. **Model Composition*Chint NXM-1000S/3300-1000A Molded Case Circuit Breaker*

   - **NBPLE**: It is a series of residual current operated circuit breakers under Chint (CHNT), which may be for specific channels or old models.

   - **63**: The rated current is 63A, suitable for the overall protection of household or small commercial circuits.

   - **2P**: It has a two-pole design, which can disconnect the live wire and the neutral wire simultaneously, providing more comprehensive short-circuit and overload protection.

   - **63**: It may be a repeated marking of the rated current or tripping characteristics (such as the C-type curve, suitable for conventional loads).

2. **Key Parameters*molded case circuit breaker  Price*

   - **Rated Voltage**: 230V (single-phase) or 400V (three-phase), which needs to be confirmed according to the actual usage scenario.

   - **Residual Operating Current**: Usually 30mA (for personal safety protection) or 100mA (for fire protection), but some models may support multi-level adjustment.

   - **Breaking Capacity**: 6kA (common in household use) or higher, and it needs to be selected according to the short-circuit current requirements.

   - **Certification**: It has passed the China CCC certification, and some models may comply with international standards such as CE and UL.

II. Functions and Application ScenariosChint NXR series thermal overload relays price

1. **Core Functions*CHINT circuit breaker price**

   - **Residual Current Protection**: When the residual current exceeds the set value (such as 30mA), the power supply will be cut off within 0.1 seconds to prevent the risk of electric shock.CHINT surge protector price

   - **Overload/Short-circuit Protection**: It is realized through a bimetallic strip and an electromagnetic release, suitable for scenarios such as households and shops.

   - **Manual Test Button**: Regularly detect whether the residual current protection function is normal.Schneider Circuit Breakers price

2. **Applicable Scenarios*Schneider LRD Thermal Relay Price*

   - **Main Incoming Line Protection of Residential Buildings**: Replace the traditional air switch to provide residual current protection.

   - **Commercial Lighting or Small Power Equipment**: Such as air conditioners, water heaters, etc., to prevent residual current caused by aging or humidity of the lines.

   - **Outdoor Equipment**: It is necessary to confirm whether the protection level (such as IP20) meets the installation environment requirements.

   - **Discount Channels**: Batch discounts may be obtained by contacting through distributors or WhatsApp. Specific quantity and delivery address need to be provided.

2. **Purchase Precautions**

   - **Model Confirmation**: Give priority to checking the complete model on the product label (such as NBPLE-63-2P-C63), and avoid confusing series such as "NXBLE" and "NB7LE".

   - **Qualification Verification**: Require the supplier to provide the CCC certification certificate to ensure that the product meets the national standards.

   - **Delivery Time**: Spot goods usually take 1-3 days, and future goods may take 2-8 weeks (such as some models in the Chint Electrical Appliance Mall).

 IV. Alternative Models and Upgrade Solutions

1. **Recommended Alternative Models**

   - **NXBLE-63 2P C63**: It is a mainstream model of Chint, supporting 30mA residual current protection, with a breaking capacity of 6kA, and the price is about WA：0086-13811255435 yuan per unit.

   - **NB7LE-63 2P C63**: It is suitable for industrial or high-requirement scenarios, and the residual operating current can be selected as 100mA, with a breaking capacity of 6kA.

2. **Upgrade Suggestions**

   - **Smart Residual Current Protector**: For example, Chint's "Kunlun Series" supports remote monitoring and fault early warning, which is suitable for smart home or commercial projects.

   - **High Breaking Capacity**: If the short-circuit current is high (such as in old residential areas), a model with a breaking capacity of 10kA (such as NXB-63 2P) can be selected.

V. Installation and Maintenance

1. **Installation Requirements**

   - **Dimensions**: Refer to the dimensions of "NXB-63 2P" which are 75.5×170×7.2mm, and enough space needs to be reserved.

   - **Wiring**: Strictly distinguish the live wire (L) and the neutral wire (N), and avoid reverse connection which may lead to misoperation.

   - **Grounding**: The grounding wire must be connected to ensure that the current is conducted to the ground in case of residual current.

2. **Maintenance Key Points**

   - **Regular Testing**: Press the "test button" once a month to check the tripping function.

   - **Cleaning and Inspection**: Clean the dust after power off and observe whether the contacts are ablated.

   - **Service Life**: The mechanical service life is about 10,000 times, and it is recommended to replace it every 5-8 years.

 VI. Frequently Asked Questions

1. **How to distinguish between 1P and 2P?**

   - **1P**: Only disconnects the live wire, is small in size and low in price, and is suitable for socket circuits.

   - **2P**: Disconnects the live wire and the neutral wire simultaneously, with higher safety, and is suitable for the main switch or high-power equipment.

2. **What should I do if the residual current circuit breaker trips frequently?**

   - **Reasons**: Line leakage, overload, neutral wire grounding or equipment failure.

   - **Troubleshooting Method**: Disconnect the branch lines step by step and use a megohmmeter to detect the insulation resistance.

3. **Can it be used mixed with other brands?**

   - **Recommendation**: Give priority to choosing products of the same brand to avoid compatibility issues (such as differences in tripping characteristics).
