Surge-Trap® Pluggable STPT2 Series - AC Reinforced

Surge-Trap® Pluggable STPT2 Series - AC-Reinforced is the series of type 2 /class II devices intended for discharging 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 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.

• 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.
