200 kA clampsFor classes of LPS I and II

According to the IEC 62561-x standard series, connection compo-nents must meet certain mechanical and electrical requirements. In tests according to IEC 62561-1, they are subjected to ageing and an electrical test with three lightning current impulses of 10/350 s wave form each*. Depending on the lightning current carrying capability, a distinction is made between Class N: 50 kA (normal duty) and Class H: 100 kA (high duty).

Connection components tested according to this standard can be used for class III/VI lightning protection systems and if the lightning current is distributed in a meshed lightning protection system.

In case of class I/II lightning protection systems, the lightning current is poorly distributed or not distributed at all if air-termination rods are connected to existing mesh systems. If an air-termination rod is con-nected to a mesh/roof parapet by means of a single conductor, 100% QHVJGNKIJVPKPIEWTTGPVYKNNQYHTQOVJGCKTVGTOKPCVKQPTQFXKCVJGconnection components. The case is similar for HVIConductors or HVIpower Conductors without current distribution used for class I/II lightning protection systems. When conducting the lightning current from the high-voltage-resistant, insulated down conductor to the existing lightning protection system, the clamps/connectors are exposed to 100% of the lightning current. This would be 150 kA in case of a class II lightning protection system and 200 kA in case of a class I lightning protection system.
