Tomzn Tovpd1-60-ec Manual -
For the TOVPD1-60-EC (1 Pole), the wiring is straightforward:
To protect a sensitive refrigerator, set P1=255V, P2=185V, P3=120s.
Widen the delta between the Trip Value () and Recovery Value ( A3/A6 ). Persistent over-current trips The load demands more amperage than configured.
The device trips when line voltage exceeds the set threshold.
Range 230V–300V or OFF (Default: 270V).
This sets the maximum voltage your appliances can handle. If the grid spikes above this number, the device cuts power instantly. 2. Over-Voltage Recovery (A2) Display: A2 Range: 225V–295V (Default: 250V)

Connect the incoming hot/phase wire from your main breaker to the terminal marked IN L . Connect the incoming neutral wire to the terminal marked IN N .
The device allows voltage reading adjustment to match a reference meter.
Use or ▼ to match the maximum safe load capacity of your circuit. Press SET to save and move to the next option. 4. Recovery Delay Time
AC 230V–300V (Default: 270V)
If the display shows "oFF" and the load has no power, the unit has either been manually shut down or has tripped due to a fault, but the power has not yet recovered.
