DC surge arrester FV25B/3-500PVS is for photovoltaic (PV) solar protection 500VDC, Iimp25ka, 3poles.
1. DC surge arrester for photovoltaic system Characteristic FV25B/3-500PVS
-DC surge arrester specially used for photovoltaic system 500Vdc.
-The core parts are metal oxide vristor components with high discharge capacity.
-With Reliable control thanks to Thermo Dynamic Control disconnector.
-With remote signaling contact for control device.
-Fault indication via red mark in the inspection window.
2. Features of photovoltaic DC surge arrester FV25B/3-500PVS:
There is a thermal cutoff member inside the photovoltaic DC surge arrestor, when the protector is over-current or over-voltage and the puncture is nonseviceable, the thermal cutoff member will automatically separate from the photovoltaic DC surge protector from the electrical network, and the indication window will turn red from green.
3. APPLICATION of DC surge arrester FV25B/3-500PVS
Solar Panel, Photovoltaic (PV) System.
