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.
* 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.
