- Metering Function: Displays real-time current, voltage, and total kWh consumption.
- Adjustable Protection Parameters: Over-voltage, under-voltage, over-current, and leakage current protection thresholds can be set manually on the device.
- Automatic Reconnect: Features an adjustable delay for automatic reconnection after a protection trip.
- Durable Construction: Made with high-quality insulating and flame-retardant materials for long-term durability.
- Wide Voltage Compatibility: Operates with L N 110V and 220V systems.
Installation Guide
This device is designed for DIN rail mounting. Ensure proper ventilation around the device.
Wiring Diagram
The device has clearly marked input (IN) and output (OUT) terminals for Neutral (N) and Live (L) lines. The product is designed to cut off the Live (L) line only.
- Power Disconnection: Before starting any wiring, ensure the main power supply to the circuit is completely disconnected. Verify with a voltage tester.
- Mounting: Mount the circuit breaker securely onto a standard DIN rail within an electrical panel or enclosure.
- Input Wiring: Connect the incoming Neutral (N) wire to the 'N IN' terminal and the incoming Live (L) wire to the 'L IN' terminal at the top of the device.
- Output Wiring: Connect the outgoing Neutral (N) wire to the 'N OUT' terminal and the outgoing Live (L) wire to the 'L OUT' terminal at the bottom of the device.
- Secure Connections: Ensure all screw-type terminals are tightened securely to prevent loose connections, which can cause overheating or arcing.
- Verification: Double-check all wiring connections for correctness and polarity before restoring power.

Operating Instructions
The TOMPD-63S features a digital display and physical buttons for operation and setting adjustments.

Image: Front view of the TOMPD-63S circuit breaker, displaying real-time voltage, current, and power readings. The buttons for control and settings are visible below the screen. Note: The device shown in the image is labeled TOMPD-63SW, but the display and button layout are similar for TOMPD-63S.
Display Readings
The digital display cycles through various parameters:
- Voltage (V): Real-time voltage of the circuit.
- Current (A): Real-time current flowing through the circuit.
- Power (kW): Real-time power consumption.
- Total kWh: Accumulated energy consumption.
Manual Settings
The device allows manual adjustment of protection thresholds using the physical buttons (typically 'SET' and arrow buttons).
- Accessing Settings: Press and hold the 'SET' button to enter the setting mode.
- Navigating Parameters: Use the arrow buttons (e.g., 'V>' or 'A>') to cycle through different adjustable parameters such as:
- Under-voltage protection (80V-210V, default: 170V)
- Over-voltage protection (120V-300V, default: 270V)
- Over-current protection (1A-63A, default: 40A)
- Leakage current protection (if applicable to this model, check device specific menu)
- Reconnect time (delay on time: 1s-500s, default: 30s)
- Voltage/current/kW calibration (-20% to 20%)
- Action time (1-30s, default: 1s)
- Adjusting Values: Once a parameter is selected, use the arrow buttons to increase or decrease its value.
- Saving Settings: Press the 'SET' button again to confirm and save the adjusted value, then proceed to the next parameter or exit setting mode.
Refer to the specific on-screen prompts and button functions of your device for precise navigation and adjustment.
Maintenance
The TOMPD-63S circuit breaker requires minimal maintenance. Regular checks can help ensure its longevity and reliable operation.
- Periodic Inspection: Annually inspect the device for any signs of physical damage, discoloration, or loose connections.
- Cleaning: If necessary, gently clean the exterior of the device with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure power is disconnected before cleaning.
- Terminal Check: Periodically check the tightness of the terminal screws to ensure secure electrical connections.
- Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent premature failure.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on / Display is blank. | No input power; Incorrect wiring; Internal fault. | Verify input power supply. Check wiring connections (N and L IN). If power is present and wiring is correct, the device may be faulty; contact support. |
| Device trips frequently. | Over-current, over-voltage, under-voltage, or leakage protection activated; Protection thresholds set too low. | Check the load connected to the circuit. Verify actual voltage and current. Adjust protection thresholds to appropriate values if they are too sensitive for your application. Investigate for actual electrical faults (e.g., ground fault, short circuit). |
| Incorrect readings on display. | Calibration error; Sensor issue. | Access the calibration settings and adjust voltage/current/kW calibration if you have a known reference. If the issue persists, the device may require service. |
| Device does not reconnect after tripping. | Persistent fault; Reconnect time set too long or to manual reset. | Ensure the fault condition has cleared. Check the 'Reconnect time' setting. If the fault is persistent, the device will not reconnect until the fault is resolved. |
