Glossary

Surge protective devices exclusively designed for installation between the N and PE conductor.

The nominal discharge current is the peak value of a 8/20 μs impulse current for which the surge protective device is rated in a certain test programme and which the surge protective device can discharge several times.

The nominal load current is the maximum permissible operating current which may permanently flow through the corresponding terminals.

The nominal voltage stands for the nominal voltage of the system to be protected. The value of the nominal voltage often serves as type designation for surge protective devices for information technology systems. It is indicated as an r.m.s. value for a.c. systems.
