Product Details

CAU4-100T Surge Protective Device 

Application
The combined devices are applicable to arrest high energy current impulses (10/350¦s waveform) which can appear in one- or three-phase overhead lines by lightning and/or discharge overvoltage occurred by switch-type (8/20¦s wave-form) over-currents. These arresters have compact (block type) mounting form. The type 1 + 2 lightning arresters must be installed into the main distribution box of the building right after the first main current limitation device and before the power meter.
Attention! The discharge capability of combined devices cannot reach the discharge capability of single devices!
These devices can also be used in properly planned photovoltaic (DC) systems as well.
