12 New Energy Horizons Opportunities and Challenges EN – Power frequency Overvoltage Protectors (POP) EN Published March The standard includes the following table: Objective: To mitigate the effects of power frequency overvoltages between phase and neutral conductor caused by breakage of neutral. 255V 275 V 300 V 350V400V Maximum breaking time No tripping 15s5s0.75s0.20s Minimum non-actuating time3s1s0.25s0.07s Standard values of break time and non-actuating time at a voltage (U a ) equal to POP Protector equipped with MCB, to complement Transient overvoltage protection solutions (SPD). Integrated Device Advantages: 1.Progressive Voltage/Time tripping curve. The tripping time depends on the magnitude of the overvoltage, ensuring quick tripping in the case of severe disturbances while avoiding unwanted activation in the event of small voltage increases. 2.Prohibition on using ground leakage or current differential as operating principles.
