1. Introduction
This manual provides essential information for the safe and effective use of the NGDOLAOV TO-Q-SY1-JWT Intelligent Circuit Breaker with Metering. This device is designed as a thermal circuit breaker with optional power metering functionality, suitable for DIN rail mounting in electrical systems.
Please read this manual thoroughly before installation and operation, and retain it for future reference.
2. Safety Information
WARNING: Electrical shock hazard. Installation and maintenance should only be performed by qualified personnel. Always disconnect power before working with electrical circuits.
- Ensure the main power supply is turned off before any installation or wiring.
- Verify that the voltage and current ratings of the circuit breaker match your electrical system requirements.
- Do not operate the device if it appears damaged.
- Adhere to all local and national electrical codes.
- The power supply must enter from the top and must be live wire + neutral wire (L+N). Live wire + live wire (L+L) cannot be used.

Figure 2: Side view and key specifications of the TO-Q-SY1-JWT Intelligent Circuit Breaker. This image illustrates the device's dimensions (18mm width, 82mm height, 50mm depth) and lists important specifications such as component type (WiFi Smart Switch), poles description (1P+N), control type (Manual, Remote), maximum current (63A), operating environment (IP20), accuracy (±2%), working voltage (AC90-240V, 50/60Hz), and communication protocol (Wi-Fi 2.4GHz).
4.3 Installation Steps
- Power Disconnection: Before starting, ensure the main power supply to the circuit where the breaker will be installed is completely turned off at the main distribution board.
- Mounting: Mount the TO-Q-SY1-JWT circuit breaker onto a standard DIN rail within your electrical panel. Ensure it is securely fastened.
- Wiring:
- Connect the incoming power supply to the top terminals labeled "Power" (L for Live, N for Neutral). Important: The power supply must be Live wire + Neutral wire (L+N). Live wire + Live wire (L+L) connections are not supported and will cause malfunction or damage.
- Connect the load (e.g., appliances, lighting circuits) to the bottom terminals labeled "Load" (L for Live, N for Neutral).
- Ensure all wire connections are tight and secure to prevent loose contacts and overheating.
- Verification: Double-check all wiring connections for correctness and security.
- Power Restoration: Once installation is complete and verified, restore power to the circuit.
5. Operating Instructions
5.1 Manual Operation
- Power ON/OFF: Use the main power button on the front panel to manually switch the circuit breaker ON or OFF.
- Signal Light: Observe the signal light for operational status.
- Metering Display (Black Models Only): The display will show real-time values for Watts (W), Volts (V), Amperes (A), and accumulated Kilowatt-hours (kWh).
5.2 Remote Operation (Wi-Fi)
The device supports remote control via a Wi-Fi (2.4GHz) enabled application. Refer to the specific application's user guide for pairing and remote control instructions.
Note: The current and voltage settings of the circuit breaker cannot be adjusted via the mobile application. The application primarily provides remote ON/OFF control and access to metering data (for black models).
6. Maintenance
- Cleaning: Periodically clean the exterior of the device with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure power is disconnected before cleaning.
- Inspection: Regularly inspect the wiring connections for any signs of loosening or damage. Check the device for any physical damage or discoloration.
- Professional Check: For any internal issues or complex repairs, contact a qualified electrician. Do not attempt to open or repair the device yourself.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | No power supply; incorrect wiring (L+L instead of L+N); tripped upstream breaker. | Check main power supply. Verify wiring is L+N. Reset upstream breaker. Consult a qualified electrician if issues persist. |
| Metering display is blank (black models). | No power to the device; device is a white model without metering; internal fault. | Ensure device is powered on. Confirm you have a black model with metering. If so, contact support. |
| Cannot connect to Wi-Fi. | Incorrect Wi-Fi password; router too far; 5GHz Wi-Fi network. | Ensure correct 2.4GHz Wi-Fi network and password. Move router closer or use a Wi-Fi extender. |
| Device trips frequently. | Overload on the circuit; short circuit; faulty appliance. | Reduce load on the circuit. Inspect connected appliances for faults. Consult a qualified electrician. |
