Overvoltage surge arrester

Overvoltage surge arrester

Overvoltage surge arrester plugs and adapters protect electrical and electronic device from mains voltage that is too high. Overvoltage can arise due to fluctuations in the power grid or natural events such as a lightning strike. Electrically powered devices are designed for a certain rated voltage. But because the mains voltage is rarely constant, they are given a tolerance range that compensates for most fluctuations. However, if there is a voltage spike outside the tolerance values, severe device damage may follow. That is why we recommend our overvoltage protection articles – from simple adapters for home use to modules for direct installation into devices.
