- Wiring Output: Connect the outgoing live wire (to the load) to the 'OUT' terminal at the bottom of the device. Secure the connection firmly.
- Neutral Wire Connection: Connect the neutral wire to the designated 'Connect N wire' terminal, typically a separate wire extending from the device.
- Verification: Double-check all wiring connections for tightness and correctness.
- Restore Power: Once all connections are secure and verified, restore power to the main circuit.

6. Initial Setup and App Pairing
To utilize the smart features, you need to pair the device with the Ewelink app:
- Download Ewelink App: Download and install the Ewelink app from your smartphone's app store (iOS or Android).
- Register/Login: Create an account or log in to your existing Ewelink account.
- Enter Pairing Mode: With the circuit breaker powered on, press and hold the blue control button on the front panel for approximately 5-7 seconds until the 'Signal' indicator light starts blinking rapidly. This indicates pairing mode.
- Add Device in App: Open the Ewelink app, tap the '+' icon to add a new device. Follow the on-screen instructions to discover and connect to the smart circuit breaker. You may need to select 'Quick Pairing' or 'Compatible Pairing' depending on the app version.
- Network Configuration: Select your 2.4GHz Wi-Fi network and enter the password when prompted.
- Device Renaming: Once successfully paired, you can rename the device for easy identification in the app.
7. Operating Instructions
After successful pairing, you can control and monitor your circuit breaker via the Ewelink app:
- Manual Control: Use the blue button on the device to manually turn it ON/OFF. The 'ON' and 'OFF' indicator lights will show the current status.
- Remote ON/OFF: In the Ewelink app, tap on the device to access its control interface. Use the toggle switch to turn the power ON or OFF remotely.
- Energy Monitoring: View real-time voltage, current, active power, and cumulative Kwh consumption within the device's interface in the Ewelink app.
- Scheduling: Set up one-time, recurring, or countdown timers for automatic power control.
- Protection Settings: Access the protection settings in the app to configure thresholds for over-current, over-voltage, max power, and min power. When these thresholds are met, the device will automatically trip to protect connected appliances.
- Data Export: The app allows for downloading energy consumption data for analysis.
8. Maintenance
- Cleaning: Keep the device clean and free from dust. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
- Connection Check: Periodically check the wiring connections to ensure they remain tight and secure.
- Firmware Updates: Check the Ewelink app for available firmware updates for the device to ensure optimal performance and security.
9. Troubleshooting
- Device Not Powering On: Ensure the main power supply is active and all wiring connections are correct and secure.
- Cannot Pair with App:
- Ensure your Wi-Fi network is 2.4GHz. 5GHz networks are not supported.
- Verify the device is in pairing mode (Signal light blinking rapidly). If not, press and hold the blue button to re-enter pairing mode.
- Check Wi-Fi signal strength at the installation location.
- Restart your router and try pairing again.
- Device Trips Frequently: Check the protection settings in the Ewelink app. The circuit may be experiencing over-current, over-voltage, or exceeding power thresholds. Reduce the load or adjust settings if appropriate.
- Remote Control Unresponsive: Check your internet connection and the device's Wi-Fi connection (Signal light should be solid).
