PSC AC Reinforced

Photovoltaic & Energy Storage SPDs - DIN RAIL - IEC AC Reinforced

PSC AC Reinforced is the series of combined Type 1+2/Class I+II devices intended for discharging lightning currents (10/350 μs) and protecting against induced voltage surges (8/20 μs). Suitable for the AC side protection of inverters or wind turbine generators with a nominal voltage of 800 V AC. The reinforced 3+1 variant ensures safe operation where high withstand voltage peaks are required or where DC offsets are induced in AC side.

Features

  • Lightning impulse current (10/350μs): 5kA per phase.
  • Maximum discharge current (8/20μs): 40kA per phase.
  • Nominal discharge current (8/20μs): 20kA per phase.
  • TNC and IT networks.
  • Un(L-L): 800 V
  • Voltage peak withstand up to 1,7kV.
  • DIN-rail mountable, plug-in format.
  • Visual and remote end of life indicators.
  • Reversible chassis to allow cable entry from above or below.
  • Mechanically coded cartridges to avoid replacement errors.
