An overvoltage is an increase in the rms value of ac According to IEEE 1159 Classification of overvoltage voltage greater than 110 percent or 0.11pu at the power frequency for a duration longer than 1 min.

Trigger voltage: 230, 275 V. The VP range of products protect electrical equipment and installations against transient overvoltage that may arise in the electrical supply. Besides, the VP range can be classified into 3 different types (C, B, B+C) which provide the A relay, normally connected, which breaks connection when the voltage goes over a threshold. You find this is Voltage Regulators used for Refrigerators and similar devices in countries that have wildly fluctuating power. When the Voltage Regulator can no longer keep the voltage below 270 volts (in a 240 volt system), then the relay breaks connection.
