Wi-Fi Three Phase Energy Meter Pakistan
PDF FILE : User's Manual
This advanced device combines precise Three-Phase Energy Metering with essential circuit protection in one compact unit. With direct wiring up to 100 Amps per phase, it is ideal for apartments, small factories, and commercial buildings in Pakistan. The integrated Wi-Fi Smart capability allows you to monitor real-time consumption (kWh), current, and voltage remotely via a mobile app, giving you actionable data to reduce your electricity bills

Over voltage limit
120V-300V 275V
If the over voltage limit is set at 300V, when the voltage is over 300V, the device will automatically switch off.
Under voltage limit
80-210V 175V
If the under voltage limit is set at 80V, when the voltage is under 80V ,the device will automatically switch off.
Under &over Voltage protection delay
1-9999Second(S) 3S
If the voltage is over or under the set value,the device will automatically switch off after the set delay time.
Over & under voltage protection recovery time
1-9999Second(S) 20S
If the voltage is over or under the set value ,the device will automatically switch off and when the voltage returns to normal value it will recover after the set delay time.
Over current limit

Leakage funtion
1. How to use it (Wiring)
On the bottom of the device, you will see two small orange/yellow terminals (separate from the main L1, L2, L3, N power terminals).
-
The CT Connection: Connect the two small wires from the red ring into these two orange ports.
-
The Power Wires: You must pass all three Phase wires (L1, L2, L3) AND the Neutral (N) through the center of the ring together.
-
Why? For leakage protection, the magnetic fields of all four wires should sum to zero. If electricity "leaks" out somewhere (like through a person or a faulty appliance), the field becomes unbalanced, and the ring senses it.
-
2. How to use it (Settings)
Once the ring is connected and the wires are through it, you can control its behavior via the Tuya Smart / Smart Life App:
-
Leakage Protection: In the app settings, you can set the "Leakage Current" threshold (usually adjustable from 10mA to 100mA).
-
Auto-Reclosing: If the device detects a leak, it will trip the power. Note that for leakage, many of these devices are programmed to lock out after 3 consecutive trips for safety—you may have to reset it manually if this happens.
-
Real-time Monitoring: The app will show a specific value for "Leakage Current" (mA). If this value is high (e.g., 20mA+) while your appliances are running, it means you have a slight insulation fault in your home wiring.
3. Troubleshooting your "uEr 112" Error
Regarding the photo you shared earlier:
-
Because your voltage is at 95V, the device has likely tripped the internal relay.
-
Important: When the relay is "OFF" (tripped), the CT cannot sense leakage because no power is flowing to the house.
-
You must wait for your main voltage to return to the normal range (above ~180V) before the CT and the app will show any data.
