FV25B/3- 320(S) is used for photovoltaic (PV) solar panel system protection.
CHARACTORS of photovoltaic surge protection device FV25B/3- 320(S):
1. Consist of a base part and plug-in protection component, for using in the lightning protection zones concept at boundary 1-2
2. Core parts are metal oxide vristor components with high discharge capacity
3. Low residual voltage and quick response
4. Thermal cut off control thanks to Thermo Dynamic Control disconnector
5. Photovoltaic surge protective device without remote signaling contact for control device
6. Window indication via red mark in the inspection window
7. Photovoltaic surge protective device with low residual voltage, can be multi-parallel connected for different distribution systems
