Chint NBHLE32-C16 is a residual current operated circuit breaker

Chint NBHLE32-C16 is a residual current operated circuit breaker (earth leakage protector) suitable for low-voltage distribution systems. It is mainly used for overload, short-circuit and leakage protection in household, commercial and industrial environments. The following is a detailed analysis based on search resources:

 I. Model Interpretation and Core Parameters

1. **Model Meaning**  

   - **NBHLE**: The code for Chint's residual current operated circuit breaker series (some data shows that there may be the NXBLE series; the two have similar functions but different naming rules, and confirmation with specific products is required).  

   - **32**: Frame current rating, indicating that the maximum carrying current of the circuit breaker is 32A.  

   - **C16**:  

     - **C**: Trip curve type, suitable for scenarios with regular current fluctuations such as lighting and resistive loads (e.g., household appliances).  

     - **16**: Rated current of 16A, which is the maximum continuous current during normal operation.

2. **Key Parameters**  

   - **Rated voltage**: 230V (single-phase) or 400V (three-phase), with a frequency of 50Hz.  

   - **Leakage protection characteristics**:  

     - Leakage operating current: 30mA (quickly cuts off the power supply to prevent electric shock hazards).  

     - Trip type: Electronic, with fast response speed and high precision.  

   - **Breaking capacity**: 6kA (maximum breaking capacity in case of short circuit, in line with IEC 61009-1 and GB/T 16917.1 standards).

 II. Functions and Application Scenarios

1. **Core Functions**  

   - **Overload protection**: When the current exceeds 16A, the circuit breaker triggers tripping through the thermal deformation of the bimetallic strip.  

   - **Short-circuit protection**: The electromagnetic tripping mechanism instantly breaks the circuit under short-circuit current (usually 5-10 times the rated current).  

   - **Leakage protection**: When a leakage current ≥30mA is detected in the line, the power supply is cut off within 0.1 seconds to prevent personal electric shock and equipment damage.

2. **Applicable Scenarios**  

   - **Household power distribution**: Such as lighting circuits and socket circuits, which can replace the combination of traditional air switches and leakage protectors.  

   - **Commercial and industrial use**: Suitable for places with high requirements for circuit safety such as offices and small factories, especially suitable for loads such as motors and electric heating equipment.  

   - **Temporary electricity use**: Such as mobile distribution boxes in construction sites and outdoor activities, providing portable safety protection.

 III. Certification and Compliance

1. **Domestic certification**  

   - Passed China Compulsory Certification (CCC) and complies with GB/T 16917.1 standards to ensure product quality and safety.  

   - Some models may have obtained CE certification, meeting the access requirements of the European market.

2. **International applicability**  

   - **US market**: There is no clear mention of UL certification in the current search resources. If it is to be used in the US, it is recommended to confirm compatibility through authorized dealers or choose alternative models that meet UL standards (such as some models in the NXBLE series).  

   - **Other regions**: Complies with IEC international standards and is applicable to most countries and regions using 230V/400V voltage.

 IV. Installation and Purchase Suggestions

1. **Installation points**  

   - **Wiring method**: Supports multiple pole numbers such as 1P+N, 2P, and 3P, and should be selected according to the circuit type (e.g., 2P for single-phase, 3P for three-phase).  

   - **Rail installation**: Adapts to TH35mm standard rails, with simple installation and space-saving.  

   - **Environmental requirements**: Operating temperature -5℃~+40℃, humidity ≤95% (no condensation), altitude ≤2000 meters.

2. **Purchase considerations**  

   - **Current matching**: Calculate the current according to the total power of the load (e.g., 16A corresponds to approximately 3.5kW single-phase load) to avoid misoperation caused by overload.  

   - **Pole number selection**: It is recommended to use 2P for single-phase circuits (to cut off both live wire and neutral wire at the same time) and 3P+N for three-phase circuits (with neutral wire protection).  

   - **Breaking capacity**: Select models with 6kA or higher breaking capacity (such as 10kA) according to the short-circuit current level to ensure reliable breaking in extreme cases.

V. Price and Purchase Channels

1. **Price**  

   - The price of a single unit is approximately 14-101 RMB, depending on the pole number and packaging specifications (e.g., 1P+N C16 is about 16 RMB, 2P C16 is about 28 RMB).  

   - Discounts are available for bulk purchases (such as 5 pieces/box, 60 pieces/carton), which is suitable for engineering projects.

2. **Purchase channels**  

   - **International**: Purchase through Chint's overseas agents via Whatsapp: 0086-13811255435. It is necessary to confirm transportation costs and certification requirements.

 VI. Frequently Asked Questions

1. **The difference between NBHLE and NXBLE**  

   - Both are Chint's leakage circuit breaker series with similar functions, but NXBLE is an updated model. Some models support higher breaking capacity (such as 10kA) and modular design, and are suitable for scenarios with higher reliability requirements.

2. **How to verify the authenticity of the product**  

   - Authentic products have anti-counterfeiting labels on the packaging, and the serial number can be queried through Chint's official website or customer service hotline.  

   - Check the product appearance: the handwriting is clear, the plastic shell has no burrs, and the contacts are made of red copper with a smooth surface.

3. **Can it replace models of other brands**  

   - It is necessary to ensure that the electrical parameters (such as rated current, breaking capacity) and installation dimensions are consistent. It is recommended to give priority to upgraded models of the same series (such as NXBLE-32 replacing NBHLE-32).

Summary

Chint NBHLE32-C16 is a cost-effective leakage circuit breaker, suitable for household and small and medium-sized commercial scenarios. Its core advantages lie in multiple protection functions, compliance with international standards, and convenient installation methods. If used in the US, it is recommended to confirm the UL certification status through authorized channels or choose compatible models. When purchasing, it is necessary to select the appropriate pole number and breaking capacity according to the load characteristics to ensure the safe and reliable operation of the circuit.
