How to Use RCCB : Examples, Pinouts, and Specs
Design with RCCB in Cirkit DesignerIntroduction
A Residual Current Circuit Breaker (RCCB) is a critical safety device designed to protect individuals and equipment from electrical hazards. It works by detecting an imbalance between the live and neutral wires, which typically indicates leakage current due to insulation failure or accidental contact with live parts. When such an imbalance is detected, the RCCB quickly disconnects the circuit, preventing electric shock and reducing the risk of electrical fires.
The AR-008/NL1 RCCB 2 pole with Auto Reset, manufactured by Zhejiang CHINT Electrics Co., Ltd., is a high-quality RCCB with an automatic reset feature, making it ideal for applications where uninterrupted power supply is critical.

Usage Instructions
How to Use the RCCB in a Circuit
Preparation:
- Ensure the power supply is turned off before installation.
- Verify that the rated voltage and current of the RCCB match the circuit requirements.
Wiring:
- Connect the live input wire to the L (Line) terminal and the neutral input wire to the N (Neutral) terminal.
- Connect the live output wire to the L (Load) terminal and the neutral output wire to the N (Load) terminal.
- Ensure all connections are secure and properly insulated.
Testing:
- After installation, turn on the power supply.
- Press the Test Button on the RCCB to simulate a fault condition. The RCCB should trip immediately.
- If the RCCB does not trip, check the wiring and ensure the device is functioning correctly.
Operation:
- The RCCB will automatically reset after tripping if the fault condition is cleared.
- Regularly test the RCCB using the test button to ensure proper functionality.
Important Considerations and Best Practices
- Always follow local electrical codes and regulations during installation.
- Do not exceed the rated current or voltage of the RCCB.
- Avoid installing the RCCB in areas with excessive moisture or dust without proper enclosures.
- Periodically inspect the RCCB for signs of wear or damage.
- Use a compatible enclosure for outdoor installations to protect the RCCB from environmental factors.
Troubleshooting and FAQs
Common Issues and Solutions
