Surge protection for photovoltaic applications
14 October 2024
THE NEW surge protective devices in the Valvetrab SPP product family from Phoenix Contact offer forward-thinking installation and safety features. They are therefore also suitable for PV applications.

The new disconnection feature responds even more quickly in the event of an overload, which provides additional safety. The main and auxiliary circuits are now fitted with double insulation. The air clearances and creepage distances are achieved by extended screw shafts and insertion funnels on the product. This measure also provides touch protection. A major installation advantage is the reduced tightening torque of just 3 Nm instead of 4.5Nm. In addition, the status display on the individual protective plugs has been optimised. Here, a clear red-green display makes it possible to read the plug status on site.
The PV products in the Valvetrab SPP product family are available as pure type 2 surge protective devices for various voltage levels from 600 to 1500V DC. In addition, a type 1 lightning current arrester for 1000V DC is also available. The surge protective devices are available with and without remote indication contact.
