Overvoltage protections

Overvoltage protection devices are intended for the protection of appliances, electrical installations and living creatures in a building. Lightning current arresters (T1) safely arrest extremal lightning currents. Surge voltage arresters (T2, T3) limit surge voltages arising from switching processes in a network or in lightning stroke. Application for low-voltage networks 230/400 V AC and up to 1 000 V DC.
