They form the second protection level in a three-level surge protection design. SPDs of type 2 must be able to protect against surge voltages from indirect lightning strikes or switching operations. Following our tradition, this year the product range of OEZ overvoltage protection devices has also been extended with another, technically more advanced  Most power supplies offer some form of overvoltage-protect (OVP) circuit. The OVP circuit's purpose is to detect and then quickly pull down the overvoltage  The Thyristor or SCR, Silicon Controlled Rectifier can be used to provide overvoltage protection in a power supply circuit. By detecting the high voltage, the circuit  Power frequency overvoltage protection devices are used in combination with circuit breakers, RCCB (Residual-Current Circuit Breaker) or RCBO (Residual  Our overvoltage protection solutions provide reliable fuse protection against high voltages for electrical equipment and systems (e.g., Varistor terminal blocks).

Surge Protective Devices are the devices that are used to protect the system from voltage spikes. It is an umbrella term that is used to represent any protective device used for overvoltage protection. SPD is designed to limit transient over volt age and divert current waves to earth, to limit the amplitude of this overvoltage to a value which is not dangerous for the electrical installation s 8 Guide to Surge Protection Devices Surge protection devices are classified according to their standard into different types • Type 1 - SPD which can discharge partial lightning current with a typical waveform 10/350 μs.
