4-pole, 3-phase class C surge protector.
A surge arrester, also known as a lightning arrester or surge protection device, is specialist equipment that effectively protects electrical apparatus against transient overvoltages. Its purpose is to limit the duration and frequency of follow currents, significantly improving installation safety and durability. Surges may occur, among other situations, when an unloaded overhead line is switched on or off, or as the result of a direct lightning strike. They can seriously damage insulation and other network components, which is why suitable arresters are a key element in protecting electrical and photovoltaic installations.
