OVR WT surge protective devices - Wind turbine networks

Due to their height, wind turbines have especially high exposure to lightning, they need high
capacity and reliable lightning and surge protection.
The OVR WT family takes into consideration the specificity of wind installations with 5
a high peak repetitive voltage withstand (Urp up to 3 kV) ensure a safe protection to Wind
applications.
It can be DIN mounted with the OVR.
