If the unit keeps resetting, check your U-Hi limit. If your house runs at 240V, don't set the cutoff to 240V; set it to 255V.
After a spike, the power will only turn back on once the voltage drops below this level. 3. Under-Voltage Protection (A3) Display: A3 Range: 140V–210V (Default: 170V)
Features a built-in voltmeter and kWh display with an optional backlight mode for visibility in dark panels.

Dedicated light-emitting diodes indicate whether a trip was caused by an Over-voltage (U>), Under-voltage (U<), or Over-current (I>) event.
I can then calculate the exact parameters you should program into the device. Share public link
The TOMZN TOVPD1-60-EC is an adjustable 230V AC (50/60Hz) relay designed for over/under voltage and over-current protection, fitting standard 35mm DIN rails. It features user-configurable settings, including adjustable voltage thresholds (230V–300V/140V–210V), current limits (1A–63A), and recovery/action time delays. Detailed operational settings and troubleshooting codes are accessible through a menu system holding the "SET" button.
