4. Setup and Installation
Before proceeding with installation, ensure all power is disconnected at the main supply.
4.1 Mounting
- The TOB1S-63M is designed for DIN rail mounting.
- Attach the circuit breaker securely to a standard 35mm DIN rail within an appropriate electrical enclosure.
4.2 Wiring
Refer to the wiring diagram printed on the device for correct connections. Use appropriate gauge wiring for the rated current.
- Connect the incoming power supply (Line and Neutral) to the 'Power N' terminals at the top of the device.
- Connect the load wiring to the 'Load N' terminals at the bottom of the device.
- Ensure all screw-type terminals are tightened securely to prevent loose connections and overheating.
- Connect the external WiFi antenna to the designated port on the device.
5. Operating Instructions
5.1 Manual Operation
The circuit breaker can be manually switched ON or OFF using the red toggle levers on the front of the device. Push the levers up for ON and down for OFF.
5.2 Smartlife/Tuya App Pairing
- Download the 'Smartlife' or 'Tuya Smart' app from your mobile device's app store.
- Register or log in to your account.
- Ensure your mobile device is connected to a 2.4GHz WiFi network.
- Power on the circuit breaker. The 'Signal' indicator light should be blinking. If not, press and hold the 'Press 10s network' button for 10 seconds until it blinks rapidly.
- In the app, tap '+' to add a device, then select 'Electrical Engineering' > 'Circuit Breaker (Wi-Fi)'.
- Follow the on-screen instructions to connect the device to your WiFi network.
5.3 Remote Control and Parameter Settings
Once paired, you can use the Smartlife/Tuya app to:
- Remotely switch the circuit breaker ON or OFF.
- Monitor real-time voltage, current, and power consumption.
- Adjust the over-voltage protection range (250-300V).
- Adjust the under-voltage protection range (150-200V).
- Set the current limiting protection (1-63A).
- View historical data and set schedules.
6. Maintenance
The TOB1S-63M circuit breaker requires minimal maintenance.
- Periodically inspect the device for any signs of physical damage or loose connections.
- Ensure the ventilation openings (if any) are clear of dust and debris.
- Clean the exterior with a dry, soft cloth. Do not use liquid cleaners or solvents.
- For any internal issues, contact qualified service personnel.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | No incoming power; incorrect wiring. | Check main power supply. Verify wiring connections according to the diagram. |
| WiFi indicator not blinking or connecting. | Incorrect pairing mode; WiFi signal too weak; wrong WiFi frequency. | Press and hold the network button for 10 seconds to enter pairing mode. Ensure device is within WiFi range. Confirm your router is broadcasting a 2.4GHz network. |
| Circuit breaker trips frequently. | Overload; short circuit; over/under voltage condition. | Reduce load on the circuit. Check for short circuits in wiring or connected appliances. Review and adjust over/under voltage and current limit settings in the app. |
| Remote control not working. | No internet connection; app issue. | Check your home internet connection. Ensure the device is connected to WiFi. Restart the Smartlife/Tuya app. |
