Modular surge protective devices of T2 class are dedicated to protect LV power supply installations against induced and switching overvoltages.
They should be installed as the second level of protection in floor boards, sub-switchboards.
Surge protectors should be installed in the places where electrical installations enter the building.
In buildings without lightning protection system and with cable line connection, surge protectors of this type provide sufficient protection, without the need to install T1 class surge protectors.
A surge arrester, lightning arrester or surge protector is a device designed to protect electrical apparatus against transient overvoltages, limiting the duration and frequency of the consequent current.
Overvoltages can arise, for example, when switching on or off an unloaded overhead line, or when lightning strikes an overhead line, they can damage the insulation and other network components.
