PSM AC Reinforced
Photovoltaic & Energy Storage SPDs - DIN RAIL - IEC AC Reinforced
PSM AC Reinforced is the series of type 2 /class II devices intended for discharging induced voltage surges (8/20 μs). Suitable for the AC side protection of inverters or wind turbine generators with a nominal voltage of 690 and 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
- Maximum discharge current (8/20μs): 30kA per phase.
- Nominal discharge current (8/20μs): 15kA per phase.
- TNC and IT networks.
- Un(L-N/L-L): 400/690V & 800 V.
- Voltage peak withstand up to 2,2kV.
- 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.
