Surge-Trap® Pluggable STPT12 Series - AC Reinforced

Surge-Trap® Pluggable STPT12 Series - 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), in accordance with IEC/EN 61643-11 . 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.

• 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.
