ОМ-163 is designed to protect (disconnect) the equipment (load) connected to it in the following cases:
− exceeding the threshold value of the controlled parameter;
− deviation of the mains voltage from the set values;
− excess of the temperature of the contact group (85 °С).

ОМ-163 can be used as:
− power consumption limiting relay;
− voltage relay;

— current overload relay;

− energy meter (indication of total, active, reactive power, current consumption and mains voltage).

ОМ-163 is powered by the circuit that feeds the load. ОМ-163 displays the value of the parameters and the status of the relay using LED indicators and display.
