Surge Protective Device (SPD) 3 Phase

FV 20 / 3+NPE three phase surge protective devices / surge protector / surge protection device / SPD are suitable for lightning and over-voltage protection in AC 50/60Hz, 230/400V.

There is a thermal cutoff member inside it, when the device is over-current or over-voltage and the puncture is nonseviceable, the thermal cutoff member will automatically separate from the protector from the electrical network, and the indication window will turn red from green.
