 II. Installation and Wiring GuidelinesSchneider Circuit Breakers

1. Preparation before Installation

- **Tools**: Screwdriver, wire stripper, torque wrench (a torque of 8-10N·m needs to be applied).

- **Materials**: Copper core wires below 6mm² (multi-strand flexible wires are recommended), and flame-retardant wire conduits.

- **Safety Measures**: Disconnect the main power supply and operate after confirming there is no voltage with a tester.

2. Installation StepsChint NXC series small contactors

1. **Fixing the Circuit Breaker**

   - Snap the circuit breaker onto the 35mm rail of the distribution box, ensuring that the clips on both sides are fully fastened to avoid loosening.

   - The spacing between adjacent circuit breakers should be ≥ 20mm to ensure heat dissipation.

2. **Wiring Requirements**

   - **Incoming Line Terminals**:

     - Connect the live wire (L) to the 1P terminal on the left side, and the neutral wire (N) to the N terminal on the right side.

     - Strip the wire about 10mm in length, insert it into the terminal and tighten the screw to ensure there is no looseness.

   - **Outgoing Line Terminals**:

     - Connect the live wire of the load to the 1P outgoing terminal, and the neutral wire to the N outgoing terminal.

     - In the case of a three-phase circuit, ensure that the neutral wire is connected synchronously with other phase wires.

3. **Residual Current Protection Test**

   - After the installation is completed, press the **Test Button (TEST)**, and the circuit breaker should trip immediately.

   - After restoring the power supply, test again to confirm the normal function.

3. Precautions

- **Neutral Wire Connection**: The neutral wire must be connected through the N terminal, and it is prohibited to disconnect or bypass it.

- **Load Matching**: Avoid overloading (long-term load ≤ 27A), otherwise it may lead to misoperation.

- **Environmental Requirements**: Keep away from high-temperature, humid or corrosive environments to avoid affecting performance.

 III. Application Scenarios and Selection Suggestions

1. **Typical Applications**

   - **Residential Power Distribution**: Socket circuits in wet areas such as kitchens and bathrooms, and high-power equipment such as electric water heaters and air conditioners.

   - **Commercial and Light Industry**: Lighting and socket systems in small offices and convenience stores.

   - **New Energy Field**: Protection of the AC side of photovoltaic inverters and energy storage systems (DC compatibility needs to be confirmed, and it is recommended to contact technical support).

V. Fault Troubleshooting and Maintenance

1. **Common Problem Handling**

   - **Frequent Tripping**:

     - Check if the load is overloaded or if there is leakage in the circuit.

     - Confirm whether the neutral wire connection is firm to avoid poor contact.

   - **No Action**:

     - Check if the test button is normal or if the residual current module is damaged (it needs to be returned to the factory for repair).

   - **Contact Heating**:

     - Check if the wiring terminals are loose or if the load exceeds the rated current.

2. **Regular Maintenance**

   - Clean the dust in the arc extinguishing chamber every quarter and measure the contact resistance of the contacts (≤ 50mΩ).

   - Calibrate the tripping characteristics with a test bench every year (the action time should meet the standard).

VI. Accessories and Extended Functions

- **Optional Accessories**:

  - **Auxiliary Contacts (AX-X1)**: Used for remotely monitoring the status of the circuit breaker.

  - **Shunt Trip Device (SHT-X1)**: Trips by an external signal (such as a fire alarm system).

  - **Alarm Contacts (AL-X1)**: Sends out audible and visual alarms in case of a fault.

- **Customized Requirements**:

  - DC voltage compatibility (contact Chint's technical team).

  - IP55 protection level enclosure (suitable for outdoor or dusty environments).

VII. Safety Warnings

1. **Prohibited Operations**:

   - It is strictly prohibited to disassemble or modify the circuit breaker while it is live.

   - It is prohibited to mix the neutral wire with the ground wire, which may lead to equipment damage or electric shock.

2. **Emergency Situations**:

   - In case of a short circuit or leakage, cut off the main power supply immediately and have it repaired by a professional electrician.
