Parameters

Impulse current (Iimp)

This is the peak current that the SPD can withstand without failing. The wave-

form of the applied current is normalised as 10/350 μs, used in Class I SPD.

Maximum discharge current (Imax)

This is the peak current it can withstand in a single pulse without failing. The

waveform of the applied current is normalised as 8/20 μs. Used in Class II SPD.

Nominal discharge current (In)

This is the current that the device is capable of shunting to ground at least

20 times without failing.

Level of protection (Up)

This is the parameter that characterises the action of the protection device

against surges by limiting the voltage between its terminals. It must be less

than the surge withstand capacity given by the category of the equipment

to be protected. However, if the protector is far from the equipment to be

protected it may be necessary to use additional protectors.

Maximum continuous operating voltage Umax (Uc)

This is the maximum AC or DC voltage which may be continuously applied

to the terminals of the SPD.
