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.
