Function

Surge protection devices (SPDs) connect all active and protection wires at the site where they are installed. They constantly monitor the voltage between active wires, and between active wires and the earthing.

In case of voltage surges they create a short-circuit between the concerned conductors. This short circuit reduces the voltage surge to an acceptable value.

SPDs employed as part of the structure's fixed installation are classified according to the requirements and loads on the installation sites as surge protective devices Type 1, 2 and 3 (or class I, II, III) and tested according to IEC 61643-1.
