OVR T2 3L 40-320 P U Surge Protective Device
Long Description
Type 4 UL (Type 2 IEC) SPD’s are designed to discharge the currents generated by indirect
lightning strikes causing induced or conducted overvoltages on the power distribution
network.
They are characterized by an 8/20μs waveform (Imax). Higher is the Imax, more powerful
they are.
They are installed in the main distribution switchboard but also in sub-distribution board.
They have a low residual voltage Upoften compatible with the withstand voltage of the
equipment to protect. If this is not the case or the cable length to the equipment is longer
than 10m, another level of coordination with OVR T2 will be needed.
