OVR T2 1N 40-440 P TS QS Surge Protective Device

Descripción

Type 2 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 Up often 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-T3, OVR T3 will be, needed.
