OVERVOLTAGE PROTECTION
Our portfolio consists of different types of Surge Diverters for various applications:
LIGHTING ARRESTERS CLASS I / T1/ B
So-called lightning arresters are Surge diverters used against direct lightning strikes. The special feature of these SPDs is their lightning current capacity, which has been tested in accordance with the international standard SPD Class I (IEC61643-1). Unlike other Surge diverter types, these SPDs are tested with the curve form 10/350 μs (this curve form meets the requirements for energy and charge). Critical parameters: peak current (limp), specific power, and charge.
For sensitive end devices, it is necessary to use a coordinated equipment fine protection in addition. These SPDs, marked as T3 or III (former classification “D”) is validated by means of a hybrid generator and
